First details about the massive project

Mon Général!

The new title was announced a few days ago. We're still amazed how well the announcement was received - thanks to every one of you, who dropped comments, encouragement, and re-posted to spread the word! It is really humbling to see such support!

Already, a lot of questions have been posted about this title. For this first devblog, where the imperial cat is finally out of the bag, we'll give a rough idea of our massive project, hopefully answering many of the pending questions in rough detail. Like said, we're early in the development and all details are not yet set in stone.


When will it be released? Will there be an Early Access release?

We're still early in the development, pre-alpha, so to say. At this point we have no exact release date in mind. The situation is similar to what it was when we first announced Grand Tactician: The Civil War (1861-1865). We know this project is massive. So, how to eat an elephant of this size?

Of course the answer is in pieces. Our approach is to utilize Early Access. Like when developing GT1, we're still a very small team of developers: the core team is just three people - though unlike when starting working on GT1 basically from zero experience, we've now worked together for almost 10 years, and learned a lot.

This said, the development roadmap is built in three parts: pre-release, Early Access, and post-release. At some point we'll drop some details about the first part, but in the grand scheme of things, the concept is a bit different from what we had with GT1. With that game, we tried to push every feature into the EA release, which resulted in quite a rough start, with a lot of bugs and features that didn't work properly.

We have learned from that, and as such, Napoleonic Wars Early Access will contain already properly playable content, but not all the scenarios, nations or campaign features. These we will keep adding during the EA period. The first campaign we are working on is Italy 1796-1797, with two major nations: Revolutionary France and Austria (units of these armies can be seen in the announcement trailer video). This is one of the theatre-specific focus campaign, as mentioned in the game's store page. It will not be a simple quick campaign like many know from Total War, but with proper army hierarchies, historical game play and 1:1 scale in troops.

While creating this campaign, we are at the same time building the grand campaign map that will cover the whole of Europe. In the Italian campaign diplomacy will not yet be an issue, so this campaign feature will be added later during the EA. The EA period will end, when all the intended feature modules, different nations and campaigns are ready. It'll take time, but in the end the elephant shall be fully consumed.


The scale is larger than before, how is the performance?

We are rebuilding the game engine from ground zero. This is because during the development of GT1, we learned a lot, and at the same time development tools and technology took many big steps. Napoleonic Wars is coded in a different way, which now allows us to gain full advantage of today's technical environment.

Improving performance has been one of the key points in rebuilding the engine. At the same time, we wanted to have as big a scale as possible. With the detailed combat simulation we have, it's of course a balancing act between performance and scale. But we can safely say already, that the performance is much better than in GT1 - getting double the FPS on average, with large armies. With a high spec computer, the difference is more pronounced.


What will be the main differences compared to The Civil War (1861-1865)

This is written with the assumption that the reader is well aware of what GT: TCW contained and how it worked technically.

First of all, as mentioned above, the code is re-written from top to bottom. This means many concepts and the vision may be shared, but at the same we will do our best to improve the technical implementation. The aim here is better performance, less "clunkiness", a more challenging AI opponent and in some areas (like UI) some streamlining, but without sacrificing the complexity of the simulation. As specific examples, the supply system and economy will receive an overhaul, especially from an understandability point of view, and there will be a diplomacy layer.

Unlike GT1, Napoleonic Wars contains a built-in localization infrastructure. This allows translating all the game's text elements. The game will be released with a number of localizations. With the tools available, the community may also add their own localizations.

Moddability is higher than in GT1. Many of the game's elements are exported to an external data -library, from where the engine then reads them. This will allow modding unit textures, sounds, commanders, units and their formations, and also maps, to name a few. Switching mainly to editable data files makes modding a lot easier, as different data files, still containing hundreds to thousands of lines of info, will also contain the descriptions.


Will there be a multiplayer option?

This is not part of the pre-release or Early Access roadmaps, and for this reason we will not promise it in the Steam store page. This time it's highly likely we will look into this in detail at one point, but multiplayer mode will not be a simple topic to implement with the complex systems and datasets we have in this game.


Could I become a beta-tester?

Thank you for the many offers received. It's heartening so many people are willing to help! At this point, beta testing is not yet topical. We will let you know when things have developed further and if such public beta testing would take place. We are also planning on using a Steam beta option during the Early Access period, where players could, if they want, run the latest beta version of the game (contributing to bug hunting), or stick to the most recent public version.


En Avant

As development progresses, we will keep answering further questions in these devblogs, and releasing more detailed information about the game. Blogs are aimed to be released approximately each month for now, on the game's Steam page. Some further information may drop on the forums.


Thank you for following us! Cheers,

Line Infantry during the Italian Campaign (1796-97)




Mon Général!
Napoleonic combat and tactics emphasize battalions, squadrons and batteries as the main tactical units. In Grand Tactician: Napoleonic Wars (1792-1815) they are the playable units - a bit like brigades are in GT:CW (GT1). During the timeline there are big changes in both tactical and operational levels. Battles in 1810- look different from those in the 1790s.

This first unit type preview will focus on Line Infantry, the main tool of the Napoleonic battlefield. As mentioned in the previous dev blog, the first campaign we are developing is Italy 1796-97, so we'll focus on the main belligerents and tactics of that theater. In later blogs, we will look at the other unit types in similar fashion, while we are developing the campaign layer in the background.


Tactical Development and Firepower

During this era we see Line Infantry battalions march and fight in tightly packed formations, soldiers forming shoulder-to-shoulder to maximize the density of muskets firing per meter of frontline. The main enabler of this was the development of flintlock muskets. A quick recap of how we got here:

During the rise of the musket, which can be observed taking place during the Thirty Years War (1618-1648), matchlock muskets were used. Matchlocks were slow to reload (when compared to flintlocks) and required spacing in formation, as soldiers maneuvered holding burning matches, which could ignite a neighbour's weapon by accident. Early muskets were so heavy, that a musketeer needed a rest to be able to fire the weapon.

At the beginning of the 17th Century, infantry formations still heavily relied on the pike, a ~5 meter long spear, that could be used to defend against enemy cavalry. Musketeers (or arquebusiers/calivermen – "shot") were mixed into blocks of pikemen to form pike and shot infantry units, commonly called battles, cuadros, squadrons, battalions... To maximize the shock effect of the "push of pike", the formations were deep (a Spanish Tercio of 3000 men with pike and shot ratio of 1:1, formed into a tactical "square of terrain", would have its 1500 pikemen in ~27 ranks deep square). The shot were usually deployed around the pike block to provide firepower. In case of cavalry attack, the shot would seek shelter under the lowered pikes, inside or behind the pike square.

With development of tactical firing systems, reformers started to maximize/optimize firepower. A drill called "countermarch" had musketeer sleeves perform a rotation of ranks, where the front rank fired, and then retired to the rear of the sleeve to reload, while the next rank moved up and fired in turn, etc. Initially with 10 ranks deep formations, this enabled continuous volley fire. During the 30YW, these firing systems developed further, with up to three ranks firing simultaneously to maximize the shock of the volley, or "salvo", as it became known: the first rank kneeled, second stooped, and third fired standing.

With this development, along with the introduction of rapid-firing and mobile small caliber regimental guns (and later battlefield mobility for larger caliber artillery), firepower became the dominant factor in infantry tactics. Checkerboards of deep squares/oblongs were replaced with wider linear formations, use of armour diminished and all but disappeared. Bit by bit, we saw the ratio of shot to pikemen increase, with 3:1 or even higher, and lower number of ranks, usually six, being the norm at the end of the 30YW. With the invention of the bayonet, effectively turning each musket also into a "pike" (in a tactical sense), we see pikes disappearing (again) from the battlefield during the Great Northern War (1700-1721)...


Contemporary Line Tactics

Fast forward to the mid-18th Century, and we find infantry armed with flintlock muskets and bayonets. Infantry battalions are formed into thin lines, shoulder to shoulder. Firepower is maximized with controlled volley firing, with the three-rank volley being dominant. Reloading a flintlock is still a complex drill, but much easier and faster than reloading a matchlock: the average rate of fire during combat is already up to one volley a minute, with best drilled troops being able to fire multiple rounds a minute. With the tightly packed ranks, countermarch or other kind of rotation of ranks during combat is no longer used. The peak of this purely linear combat and well drilled professional soldiers sees the Seven Years War and the rise of Prussia.

While "war never changes", tactics do. Entering the starting point of GT: Napoleonic Wars, the main tactical unit, Line Infantry battalion, is fighting in three ranks. (The rather conservative Austrians are some of the last ones to remove the fourth rank.) This maximizes firepower, with all guns potentially firing, none held behind as a reserve. The Line battalion is a multi-purpose unit: firepower is the main thing, but the bayonet provides offensive shock action against a fragmented enemy line or a tightly packed wall of pointy steel, that charging cavalry will not dare to brave.

Cohesion and form are important. Maneuvers and evolutions are rigorously drilled, as a broken formation is fragile. Movement is slow, as maintaining the line requires constant dressing, a uniform cadence, and standardized movements of individual soldiers.

While small-arms have developed since the bulky arquebuses and matchlock muskets, some rules remain: the weapons are inaccurate (and aiming poor or non-existent when the closely packed mass of men releases a coordinated volley) and produce a thick milky smoke that hinders visibility during battle. Firing beyond 300 paces is not recommended. Real effect is seen when the target is within 150 paces and the men well disciplined. But still, even hundreds of muskets firing may result in a rather limited number of casualties (as can be seen in the video's Firepower Demonstrations.) Some nations, like Russia, still preferred shock action over musketry.

While the drill manuals contained a wide variety of formations, not nearly all of them were seen commonly used in the actual field of battle. To generalize, the main formations are the line, square and column. Line brings all the weapons to the fight, to fire, or when charging, to break the enemy line. In square the battalion is virtually immune to cavalry charges (if cohesion and morale are maintained!), but vulnerable to artillery fire, and the column provides fastest movement with limited firepower. To screen the battalion's main formation or to scout the way ahead, part of the men can be detached to act as skirmishers. In this role, the men use open order and loose formation, usually in pairs or threes, using terrain as cover and harassing the enemy with fire. The aim is to disrupt the enemy formation or to intimidate the enemy to open fire before the battalion is within range. Infantry battalions are still commonly reinforced with regimental cannons to bolster their firepower, following the practice from the latter half of the 30YW.


Organization and National Flavour

In the game, the units of different nationalities are not identical and contain different organizational and tactical flavours. The French and Austrian Line Infantry may appear quite similar, but they also have differences – and the commanders tend to use them differently, depending on tactical school. Let's take a closer look:


France

Entering the Revolution, the French military was in the middle of a tactical debate: which one is superior in contemporary battle, the line or the column? Using battalions in columnar formations provide weight and pressure in a narrow front, while making maneuvering much faster. Line provides superior firepower. In 1791 the main drill manual (which was to serve through the Napoleonic Wars with minor adjustments) described a line oriented, but hybrid approach. But the tactics would evolve not thanks to a manual, but out of necessity, when the quickly formed and ill-trained revolutionary battalions adapted their tactics to overcome their professional but rigid opponents.

To spread experience among all of the army, the French conducted a series of amalgamations, where old regiments were disbanded and new "demi-brigades" (to avoid using the word that resembled the cursed old regime) were formed from one battalion of regulars and two of volunteers, later the mixing taking place on the lowest levels as well. The resulting organization is what we see in Italy: a demi-brigade with three battalions, each (in full strength) slightly over 1000 men strong.

While professional training is back in the picture in 1796, experience from the early revolutionary wars has formed the French battalion tactics into something quite flexible. While line is still the main fighting formation, battalions can also deploy in open order to skirmish en masse, or use different column formations for fast mobility or even shock action with cold steel. The rigid three rank firing drill has made way to a more flexible two rank fire, where kneeling of the first rank is no longer practiced – it is commonly known, that once the rank knelt it usually tended to remain down, unwilling to stand up again to move. Also, the third rank firing can result in casualties among the other ranks, or at least a major distraction for those few trying to actually aim their fire. The third rank continues to fire if the battalion is firing by rank.

The French line battalion is organized into nine companies, eight of fusiliers and one of grenadiers. The grenadiers are the tallest, the most experienced and capable fighters of the battalion, many units already sporting the later much more common tall bearskin hat. When preparing for battle, the companies, which are administrative units and can have uneven strength between them, are formed into Platoons (Pelotons) - one per company. The platoons are to have equal strength, as they form the building blocks of the formations and firing systems. The grenadier company may remain with the battalion, or detach to form composite, elite grenadier battalions with companies from other battalions – a practice that became common during the Italian campaign.

A line battalion, if the soldiers are sufficiently trained, can detach one of the platoons to form a line of skirmishers. The skirmishing tactics are not yet formalized, so the formation is usually a loose line of men working in pairs, with a small group of leaders and drummers for signals slightly behind, to maintain communication between the skirmish line and the battalion main body. It's only later, the voltigeur company will be added to the infantry battalion organization.


Austria

The Austrians have been slower to adapt – probably because there has been no need to, at least not yet. Their tactical guidelines come from the 1760s manuals. They follow the strict Prussian ordre mince, "thin order", ie. deploying into long lines for battle. The French "clouds of skirmishers" and columnar tactics have already caused some disruption, but no change yet.

The Austrian Line Infantry is divided into "German" and "Hungarian", depending on the region where the regiment comes from. While Hungarian battalions are slightly larger, tactically there are no major differences. A fusilier (line) battalion has six companies. The regiment's two grenadier companies will always form separate grenadier battalions with companies of other regiments. While a battalion's strength is on paper well over a 1000 men, normal campaign strength is, like with the French, usually around 500 men.

While the Austrian Line Infantry is drilled to use many different formations, tactically in battle they use the line as the main formation. Columns are used for long distance movement only. This makes the Austrian Line Infantry seem less flexible than their French opponents.

The six companies each form four platoons (Züge), that are the main building blocks of the different formations. In wars against the Ottomans, the Austrians have adapted a blocky square formation that is quick and simple to form from the platoons. Adapting attack column formations, or masses as they will become known, will happen later, with the need for larger reforms forced on the Austrians after painful defeats in the hands of Napoleon. The main firing method is the three-rank volley, fired either as a battalion, or in a sequence of sub-units.

But, there is some flexibility in the Austrian tactics. The third rank soldiers are the best trained and most capable ones, and the third rank may form 12 additional ad-hoc platoons. These platoons can be used to extend the line, if strength is low, or they can be detached to skirmish. Unlike the French, the Austrian skirmishing tactics are already formalized, with the skirmish line fighting in open order in pairs or threes, supports deployed behind the skirmish line to rotate men, and reserve behind the supports. This means 1/3 of the battalion's men form the skirmishing element (as opposed to 1/9 in case of the French), which provides further resilience in prolonged engagements, even if the number of actual skirmishing soldiers is similar.

Cavalry during the Italian Campaign (1796-97)

Mon Général!
Historically and in Grand Tactician: Napoleonic Wars (1792-1815) "cavalry is useful before, during, and after the battle." – Napoleon Bonaparte.*

During the Napoleonic era, cavalry played an important role in battle and during campaigns. Much of the image of Napoleonic cavalry comes from scenes of French cuirassiers charging during a field battle, usually Hollywood-style, with broken formation and each individual eager to get into some slashing action... probably not that accurate a depiction.


Roots and Role

The mounted knight, heavily armoured and highly trained, charging in with a lowered lance, was in a way the peak of European medieval warfare. With the weight of formation and unwavering determination, they were almost an unstoppable force, especially in open field battles (with dry ground). As discussed in the previous unit preview, with the introduction of infantry pike tactics, cavalry charges became a much more dangerous business.

If we look into the beginning of the 17th Century and the early years of the Thirty Years War, European cavalry had already adapted to the realities of pike and shot warfare. Heavy cavalry, most famously the cuirassiers ("black knights"), had switched their lances to a number of wheellock pistols. Lightly armoured harquebusier cavalry provided supporting firepower from further back, while irregular cavalry, hussars, Cossacks and Croats preyed on weak or unprotected flanks. The role of armour was still relevant, as higher velocity muskets able to penetrate armour from a distance were still rare.

Cavalry commonly formed into squadrons, deep formations resembling squares (the word "squadron" deriving from "square"). Depending upon the school of tactics used by an army, this was usually from 150 men in 5-8 ranks in Flanders (where battlefield cavalry operations were hampered by the terrain) to up to 1,000 men in 10 or more ranks in central Europe, especially among the Catholic forces aligned with the Holy Roman Emperor. These squadrons formed knee to knee in the charge, creating a proper battering ram that was difficult to resist – except with a cohesive and determined pike formation.

The tactic to engage intact pike blocks was called the caracole (from "snail" in Italian). In its most elegant form, one rank at a time would ride forward toward the pike block, turn left just outside the reach of the pikes, and fire their pistols into the infantry, then riding back to the rear of the squadron to reload. This was a rather ineffective tactic when it came to casualties inflicted, but it did immobilize the targeted unit and prevent own casualties. And with sufficient attrition, the infantry formation may have lost its cohesion, and then it would be the moment for a well-timed charge to break the formation. Whether the caracole tactics, as such, were still intentionally used during the first half of the Thirty Years War, or did aborted cavalry charges just resemble them, remains a favourite dispute among historians.

As the Thirty Years War continued, tactics and weapons evolved. In the battle of Breitenfeld (1631), the Swedish cavalry formed into thin lines, only 3-4 ranks deep, with "commanded" musketeer infantry deployed between the cavalry squadrons. When the imperial cavalry charged, the musketeers fired salvoes to break their formation, forcing them to abort the charge, and then the Swedish cavalry countercharged, firing their pistols and charging home with cold steel.

Fast forward a decade, and most cavalry operated in smaller, thin squadrons (usually 100-300 men in three ranks), wore little to no armour, and preferred charging home, firing their pistols as they went. They usually formed the "wings" of a field army, fighting the enemy cavalry wings and trying to outflank the enemy center, where the infantry would be posted. As lighter muskets with improved penetration power were developed, armour no longer provided protection, but became an expensive burden. Speed became more important, which also led to disbanding the commanded musketeers that slowed down cavalry, hampering its tactical flexibility. Instead, the infantry-cavalry hybrid arm, the dragoons, gained importance. Starting as pure infantry using second-rate horses to move fast, but fighting dismounted with their muskets, dragoon tactics steered more toward that of other cavalry especially after the Thirty Years War.

This development was not universal, though, not even in Europe. The Eastern European steppes were a different kind of battlefield, and there, hussars, Cossacks and other light or irregular cavalry types reigned, most famously the Polish winged hussars, who still preferred their long lances over firepower.

While the battlefield role of cavalry saw quite dramatic change, the operational role saw even bigger ones. Cavalry was always good for scouting ahead, raiding, and of limited use during sieges (the main form of combat during this era!) As the countryside became devastated and couldn't support large field armies of infantry, the proportion of cavalry increased drastically. And with this, their tactical and operational uses became more apparent and developed further.

Fast forward to the time of the earlier quote (*often attributed to Napoleon, but most likely part of aphorisms written a bit later), where cavalry's role is becoming more specialized than before. Before the battle, cavalry would scout ahead of the armies and provide them with a screen that masked the army's movement and intent, leaving the enemy commanders guessing. During the battle light cavalry usually formed on the flanks to screen or to outflank the enemy army, while the heavy cavalry was used to provide shock action and exploitation of breached lines. The true source of victory (turning a tactical victory to an operational or even strategic one) was in the pursuit, which was one of the key tasks for the light cavalry. A well-executed pursuit could often turn retreat into rout and prevent the enemy army from reorganizing.


Cavalry Organization and Tactics in Italy 1796-97

The century plus after the Thirty Years War, cavalry armament and battlefield tactics had not changed drastically. Three ranks remained the main depth of cavalry squadrons until around the mid-18th Century, when the prevalent view started to shift toward reducing the number of ranks to just two. While the third rank did add to the "weight" of the formation, it usually failed to contribute much in combat. The conservative Austrians still stick to the old school of three ranks. The squadron is the main tactical formation, as the battalion is to infantry. Squadrons are usually formed from two companies (forming the left/right wings), with a strength of between 100 and 250 troopers each. Light squadrons usually are slightly larger. Cavalry regiments form a number of squadrons, usually 4-8.

The cavalry types can be classified roughly into heavy and light cavalry, following the logic of operational uses described above. The "hay-day" (pun intended) of cavalry, with the use of large independent formations, with supporting horse artillery, is still in the future in 1796. Instead, it is common to form cavalry brigades to be attached to infantry divisions, to support the infantry's battle, or even to attach single squadrons of cavalry to infantry brigades. Forming light and fast moving vanguards or rearguards from light infantry, light cavalry and horse-artillery is common.


Heavy Cavalry

Cuirassiers (with only breast- and backplates remaining from the full-body armour) were the main heavy cavalry till the 18th Century. By the time of the Seven Years War (1756-63), dragoons had evolved from horse-mounted infantry to heavy (or "medium") cavalry. During the 18th Century, most nations abandoned the cuirass armour to emphasize speed (and to cut costs).

In 1796, Austrian cuirassiers have a fierce reputation, that of the premier heavy cavalry in Europe. They are some of the few still wearing armour, though a breastplate only. Two elite regiments of carabiniers are similarly armed. The French heavy cavalry regiments (Cavalerie) and elite carabiniers are unarmoured, but their tactical use is similar to their Austrian counterparts - the heavy cuirass was too royalist, or too cumbersome, for the fast- moving style of the Republic (one regiment, the old Cuirassiers du Roi, still retain their cuirasses, though, and are hence called "cuirassiers" in the game). While the name "carabinier" comes from the cavalry firearm "carbine," and they most certainly are armed with them along with pistols, heavy cavalry do not use their firearms in battles for ranged skirmishing, as they are all about shock action.

Austrian dragoons are formed with the cuirassiers as part of the heavy cavalry arm, and their skirmishing and dismounted days in battles are long gone. Staff dragoons provide the escorts to field commanders. The French dragoons, on the other hand, have retained the training to fight dismounted when needed (as the Spanish front will later highlight).

As the Italian theater is secondary to that of the Rhine, especially the French have mainly light cavalry and dragoons in Italy.


Light Cavalry

Light cavalry are the eyes and ears of an army. They are more useful outside of a battle than during it, moving fast to reconnoiter, screen, harass the enemy and to raid. They wear no armour, ride slightly less significant horses than their heavier counterparts, and some retain the training to skirmish with their firearms from the saddle.

Austrian light cavalry came in three forms: the chevauxlegers (literally "light horses," from French "chevaux‑légers"), a multi-role cavalry with the ability to skirmish, like their French counterparts, the Chasseurs-à-Cheval. Hussars and Uhlans have their roots in the Eastern cavalry tradition and tactics. Hussars are the premier light cavalry for speed, ferocity and raiding, while the Uhlans are armed with lances (a practice that would resurface on a larger scale in a few years' time.) The French also have their hussars, but in addition a small elite party of Chasseurs known as the Guides, hand-picked by Napoleon himself. With the formation of Polish legions, in the game the French may also field a small number of lance-armed light cavalry in Italy.


Cavalry Firearms and Skirmishing

The cavalry carbines are short weapons with limited range, and firing from the saddle is inaccurate. Most cavalry is armed with carbines and pistols (at least part of the men in a unit), but firing from the horseback is limited to a few specialist units and the use of pistols in melee. In the game, chevauxlegers and chasseurs-à-cheval (and Guides) can use mounted skirmishing tactics. The other cavalry types reserve the use of their carbines to outpost, picket, vedette and escort or guarding duties, or for foraging or fighting partisans.

Detaching "flankers" (cavalry equivalent of infantry skirmishers, also called vedettes) allow some light and dragoon cavalry units to screen their main formation to harass the enemy with carbine fire, but this too requires sufficient training.


Cavalry Battle Tactics

Heavy cavalry's main role is in battles, where they provide fast-moving and heavy-hitting capability for the commanders, and they are usually held back in reserve to punch a hole in a wavering enemy line or to counterattack on a decisive moment. Heavy cavalry has the largest horses available, and they rely upon the impact of the charge, where riders form knee-to-knee and maintain a solid front. The charge is executed at the trot (or canter), not breaking into Hollywood-style gallop of individuals, at least if the unit is properly trained. During the charge the tightly packed formation is vulnerable to artillery fire. The light cavalry in the game is versatile and fast. Good uses for light cavalry are, for example, threatening the enemy infantry to force them to form squares, effectively immobilizing them and making them vulnerable to artillery fire, fending off enemy cavalry, attacking unprotected flanks of the enemy, and pursuit.

Prolonged Hollywood -style melees are rare. Charging (or being charged by) a superior foe commonly leads to disengaging, even before contact is made. Charging a well formed infantry in the game, as in real life, is ill-advised, even if the infantry is not formed in a proper square. But, once the infantry is demoralized or their formation is broken, a well timed cavalry charge can be deadly, with the target prone to break in panic even before impact. When coming under fire, a cavalry squadron would usually try to countercharge or simply disengage out of range.

The main cavalry formation is the line, for the French in two ranks and three for the Austrians. As with their infantry, the French cavalry is known to experiment with columnar formations for charges, providing pressure against a narrower part of the enemy front. In the game, it's essential to keep the horses fresh for charges, otherwise it's likely the charge falls apart with little effect achieved.

Other commonly used formations are different kinds of columns for fast maneuvering outside imminent contact. While the Austrians are "old school" with their third rank, their light cavalry often use the additional rank to extend the line, for example when engaging in ranged combat or charging. Neither nation uses swarm tactics, such as those commonly employed by the legendary Russian Cossacks.

To maintain the formation and to coordinate maneuvers, officers and senior NCOs are deployed in the front, rear and flanks of the formation. A number of trumpeters relay the commander's orders to the squadron. To improve command and control in the confusion of battle, the officers and trumpeters usually ride white or gray horses, which will stand out from the rest, providing a beacon for the troopers to follow.

The current development situation of the Napoleonic Wars.

Mon Général!

The French Empire was not built in a day. Neither is Grand Tactician: The Napoleonic Wars (1792-1815). In this DevBlog, we'll briefly discuss the current development situation of the Napoleonic Wars.


The Battlefield

The technical features of the re-built battle layer are mostly finished. The biggest differences to GT1 (The Civil War) are the scale, ie. the number of soldiers shown on the battlefield and handled in the simulation model, and the terrain generator, which creates the battlefields from campaign map topography datasets. What remains to be finalized is the "macro-AI", responsible for maneuvers, and establishing the campaign-to-battle link, which is all about data handling in the background.

Audiovisual elements, that you can see and hear in the released videos and screenshots, are not yet final. Most elements will be further looked into, and variation added. The Italian theater specific 3D models, like houses for towns, and variety in the battlefield visuals, are in the works. We intend to add a similar papermap layer as in GT1, though this time around it's technically a bit trickier. As the map is generated, it cannot be hand-drawn as a complete map like before. Audio elements to be added include touches to improve the atmosphere, such as historical drum and trumpet signals and voice commands that can be heard when the units maneuver and fight.

The full unit roster for the 1796-97 campaign in Italy is to be augmented with Italian units. This includes one of the main belligerents, the Piedmontese (Kingdom of Sardinia), but some of the minor nations also participated in the fighting, most notably the Papal States and Kingdom of Naples. Also other forces, like those of Venice, were present, even if they did not enforce their nations' neutrality militarily - but maybe they could have in certain conditions?


The Campaign Layer

We decided to re-build also the campaign layer from scratch. The required changes were so numerous, that trying to "bend" the old campaign engine would have been more work, and the end result maybe not as good. The campaign technical infra is well underway, with UI elements being added with the remaining mechanics.

First, the campaign map. In GT1, the campaign maps were fully built in the engine's editor, which made them virtually un-moddable. This time around, the approach is more modular. There are two levels of maps: master maps and campaign maps. Master maps are large, and can contain vast areas like the whole of Europe. Campaign maps are created separately from a master map, either using the whole master map, or only a specified part of one. For us, this allows creating the master map for the Europe-wide grand campaign in parts, with each smaller campaign area populating the master map. For modders, this allows creating completely new master maps, like North America, and then "slice" smaller maps out of it for specific campaign scenarios.

The campaign map is created from multiple datasets, containing elevation (heightmap), terrain, infra, and resource data. From this a 3D mesh is created, terrain types are painted, roads, rivers and cities, etc. drawn. To facilitate different scale of campaigns, the different infra elements can be shown on the campaign map depending on their size. So, even if the Italian theater campaign map has much more details in Northern Italy, the same data set can create the same area with larger scale details for the European campaign. When generating battlefields out of the same data, even the smallest scale elements will be on the map.


The Playable Campaign Map and Military Supply System

From a game play perspective, the logic of how the campaign map infra is built is relevant. In GT1 the map is created from Important Infrastructure Points (IIPs) and cities. This creates a mesh, where each node is linked to its neighbours, and contains ownership, condition and economic data. Ownership is changed according to local military control, which can be established by deploying armies or building forts and manning them with garrisons.

In GT2, we have adjusted this model a bit, again to a more modular direction. Instead of two separate types of infrastructure, the map now contains elements we call "cities," but that can be anything from a small rural village to a large city. Each such "city" can contain different kinds of military, economy, or national buildings. These "cities" can grow, shrink, gather wealth, and be garrisoned. They can be occupied, and as part of treaties annexed, de facto changing ownership. The locations and data are drawn from moddable datasets.

The economy model, which also contains the military supply system, has been adjusted as part of this change. We have a similar supply/demand and production chain systems as in GT1, but how it "flows" on the map, and how the military can exploit it, is handled differently. Now, the goods (incl. military supplies) are moved on the map, along the main land routes and sea trade arteries. This means, military units can intercept them even without the need to capture cities.

Military units are supplied from military magazines with supply trains, and carry only limited number of supplies with them. In Italy 1796-97, an army is the "top supply unit," that contains the supply trains, and connects to available magazines. Subordinate units rely on the army level logistics tail to feed them, except if stationed nearby a magazine. This logistical system is quite heavy, vulnerable and has a limited operational reach. Stretching the supply lines too long means diminishing flow, and losing a line of communication to the base of supply can quickly lead to big difficulties.

Relying on the magazine system and long, heavy logistical tails was established during the age of enlightenment. The memory of the Thirty Years War (1618-1648), with armies like swarms of locusts consuming and destroying everything in their way, was still haunting the societies. But the old ways are still a possibility, and war can feed war. Armies may purchase supplies from the civilian population, but also simply take them, or even demand contributions to pay the soldiers' wages and fill the military coffers. Such "CIMIC" activities of course affect the mood of the population. 


Progress

On the campaign layer, many other mechanics are already in place, like the fog of war. This has been augmented with deployed reconnaissance units (mainly light cavalry) being able to not only spot enemy units farther away, but also to block their recon screens, masking the movement of the army's main body. But more about them later.

We will take a closer look at the different campaign mechanics as we finalize them and populate the map and the UI with visual elements. In the meanwhile, this month's video shows some of the player controls and how order delays work in battles. Maybe GT1 veterans can spot a few improvements here and there?

In this blog, we'll describe some of the unit system related changes vs. GT1.

Mon Général!

The campaign layer features are taking form with the unit system being added along with orders, delays and interaction. In this blog, we'll describe some of the unit system related changes vs. GT1.


Campaign Units & Management

In a campaign, the most important playable elements are the units on the map. As is the case in GT1 (The Civil War), the units and commanders can be managed by the player. While most of the main mechanics are similar as before, there are quite a few changes introduced in the Napoleonic Wars.

In GT1 the units on the campaign map are hierarchy based. In the main campaign, armies and corps are movable elements, while garrisons are fixed as divisions. Garrisons can only be placed in fortresses (and forts always have a garrison.) Even if Whiskey & Lemons introduced a system where units could be garrisoned, behind the scenes this is handled with the same fort logic, only the fort is instantly "built" and has much less defensive power than proper fortifications. This system is rigid in nature: in case you have an army with three corps, then you will have four units on the map to manage and move.

In the Napoleonic Wars, we've made this a bit more dynamic. Instead of automatically placing hierarchies on the map, units are now built into what we call "containers" (as a technical term.) What such a container contains is not strictly limited. So, a movable element on the campaign map ("container") can be anything from a single unit to a full army, or something in between. In the 1:1 scale Italian campaign the armies are built from battalions/squadrons/batteries, brigades and divisions. Want to move the army commander and two divisions as one element, while the third division operates independently and a few battalions are placed as garrisons? Now it's possible.

Another change is with the commanders. With the battalion scale, you'll have your core team of officers for the higher hierarchies (brigades, divisions, armies) and a limited reserve of available officers to replace them if needed. The pool of replacements will only slowly replenish, which means you will have to make do with the officers you have appointed at the start of the campaign, cherry picking from the nation's whole pool of officers is not possible (in Italy.) But more about commanders later...


Campaign Unit Main Mechanics

Civil War veterans will find the campaign units familiar: there's the commander with his attributes, unit experience, strength, attrition, morale, training, readiness and condition, in addition to upkeep costs and supplies. The quite abstract "intelligence gathering" from GT1 has been beefed up for an easier to understand reconnaissance system for units, while intel is also provided from other sources.

The number of men is not just one figure. First there's the full strength, ie. how many men there should be in a unit. For example a battalion could have a full strength of 1000 men. But then there's the book strength, ie. how many of those 1000 positions are actually manned. This contains also the combat-ineffective men: the wounded, the sick and the ones that are missing. So, while the before mentioned battalion may have a book strength of 700 men, number of effectives, ie. the men actually fighting, is usually much less. During the Italian campaign, among the French and Austrian units, 500 effectives was a common figure, a mere 50% of the full strength. On a good day. On bad days, even without combat, this can drop further, for example due to a spreading disease.

Experience fortifies morale and makes the units more effective in combat. Training increases the skill of the soldiers, but also their fitness and discipline. Condition affects everything, as men in rags and no food will have disciplinary and morale issues and are at risk of failing health. Paid wages allow the men to purchase required equipment that the state does not provide. Issues with payments were very common during this era, so the men probably won't go on a strike over a few months' missed payments, but as arrears accumulate, morale and discipline will falter, which may lead into troubles with the local population and desertion.

Readiness was retrofitted to GT1 as a separate mechanism, with its unique drivers. In GT2 readiness is better embedded in the unit mechanics, and is not as limiting to operations as before, which could be infuriating at times. So, instead of "hard limits" on what you can order your units to do, readiness has a big impact on order delays and ability to react to threats in a timely fashion. As a result, units with low readiness will be less effective, but not unable to perform given tasks. Rather, some order types can be unavailable due to insufficient morale or training.


Reconnaissance & Skirmishing

Reconnaissance is mostly conducted by light cavalry and light troops in general. Recce screens and patrols are automatically dispatched. When your units are ordered to conduct a forced march at the best possible speed, recon units have little time to scout ahead, and will do so mainly along main routes. With orders for a more battle ready tactical movement or screening, reconnaissance is more methodical, covering a wider area and a longer distance.

Specifying engagement orders to your units allows you to have them avoid combat, actively skirmish with the enemies, attempt to commit to a field battle, or to pursue an enemy unit. Fighting is initiated when the recon screens make contact. The initial small unit skirmishes may grow in intensity as more units are committed. A strong reconnaissance screen is able to push the enemy scouts back and to prevent them from gaining eyes on the main body, severely reducing intel the enemy is able to gather.

While there is skirmishing in GT1 on the campaign map, this time around there will be less of a shroud of mystery around what is going on and why. When a skirmish is initiated, details of this action are shown on the map as part of an overhauled information/tooltip system.



IMAGE: A pre-alpha screenshot shows some test units engaging in minor skirmishing near Voltri. Everything shown is subject to change: the map and city element graphics are all placeholders, UI is work in progress.

The development continues on track with the main focus being building the campaign layer features, while artists are working on audio and visual elements focusing on improving the battle layer before moving on to campaign.
