Light cavalry, the primary tool
During the Napoleonic era, reconnaissance primarily relied on light cavalry: hussars, chasseurs à cheval, and then lancers from 1811. These fast and manoeuvrable units were tasked with scouting ahead of columns, locating the enemy, and reporting intelligence on their positions, strength, and movements.

In-depth organization
The reconnaissance system was structured on several levels:

• Vedettes: Isolated horsemen posted as observers, ahead of the lines, forming a first alert screen.
• Outposts: Small detachments responsible for the immediate security of an army corps, controlling passage routes.
• Reconnaissance parties (or "scouting parties"): Larger groups, sometimes an entire squadron, sent on specific missions to probe a precise area, a ford, a defile, or the presumed enemy position.
• Grand reconnaissance: A larger operation, sometimes conducted by several squadrons or even an entire brigade, intended to force the enemy to reveal themselves (then referred to as "reconnaissance in force" or "offensive reconnaissance").

The role of staff officers
Napoleon attached considerable importance to organized intelligence. Staff officers, often from the corps of engineer-geographers, were sent on reconnaissance to sketch terrain, assess enemy positions, and verify the reliability of available maps—which were often inaccurate or outdated.

Complementary intelligence
Beyond cavalry, several sources fed the situation picture:

• Interrogation of prisoners and deserters, systematically after each contact
• Local intelligence obtained from inhabitants, sometimes by coercion
• Spies and secret agents, particularly in enemy territories, attached to the Emperor's cabinet
• The topographical bureau, a sort of embryonic general staff, which centralized maps, reports, and information to establish the strategic situation

A method, not improvisation
Napoleon insisted that his cavalry generals not be content with skirmishes: he wanted precise, dated, localized reports on the strength and composition of enemy units. This demand for rigor partly explains the effectiveness of the Grand Army in its campaigns of rapid movement, where knowledge of the terrain and the enemy dictated manoeuvres.


And in HistWar...
There is a specific order to perform reconnaissance.

However, depending on the options chosen, the entire enemy army may be visible, so reconnaissance missions can be ignored.

Conversely, the Conditional with or without delay options allow units not visible to the Commander-in-Chief to be hidden. Thus, it is necessary to send troops to scout the terrain and receive messages specifying the type and positioning of enemy troops.

These dispatches, sent by reconnaissance troops, are accessible immediately or not depending on the Conditional with or without delay option.

The reconnaissance unit advances towards the designated sector. In case of contact with the enemy, the unit reacts in 3 ways:

• Stop progression and await a possible engagement if the enemy wishes to fight
• Continue progression to push back the enemy
• Retreat because the enemy is judged too strong.
• In all cases, a message is sent to headquarters.

A reconnaissance unit therefore has 2 missions:

• Scout the area in front of the Army
• Prevent the enemy from reconnoitring their army.

In conclusion, just like in that era, reconnaissance is a critical mission that should not be forgotten at the beginning of a battle.
