Infantry combat formations in the Napoleonic era.

In Histwar, formation management is at the heart of tactics. Each formation radically alters the unit's statistics (firepower, morale, speed, shock resistance, and vulnerability).

Here is a detailed presentation of the different infantry formations and their tactical use.

The Line
This is the classic deployment formation for fire combat.

* Characteristics:
* Firepower: Maximum. All muskets can fire.
* Movement: Slow and difficult to maneuver.
* Vulnerability: Very vulnerable to cavalry charges (especially on the flanks) and difficult to move on uneven terrain.
* Tactical Use:
* Defense: Ideal for waiting for the enemy and breaking them with musketry volleys.
* Firefight: Essential against an enemy column or another line.
* Against Artillery: Presents a thinner target than a column (fewer losses per cannonball), but remains vulnerable to shells.
* Historical Note: The British excel in this formation (rank firing).

The Column
The maneuver and assault formation, favored by French doctrine.

• Characteristics:
  * Firepower: Low. Only the front ranks can fire.
  * Movement: Fast and easy to direct.
  * Shock (Melee): Significant bonus in hand-to-hand combat due to density and momentum.
  * Morale: More resilient when moving.
  * Vulnerability: A prime target for artillery (cannonballs pass through several ranks) and vulnerable to flanking fire.
  * Tactical Use:
  * Approach: To quickly bring troops to the front.
  * Assault: To break through an enemy line weakened by artillery or skirmishers.
  * Reserve: Allows troops to be kept compact and ready to intervene.
  * Tip: Never remain in column under sustained artillery or musketry fire without moving. Change to line to return fire or to square if cavalry approaches.

The Attack Column prioritizes shock but starts with a volley before charging.

The Square
The survival formation against cavalry.

* Characteristics:
* Defense: Immunity (or near-immunity) to cavalry charges.
* Firepower: Medium (360° firing), but less effective than a line against infantry.
* Movement: Almost none. The square is static.
* Vulnerability: Perfect target for artillery (compact mass) and infantry in line.
* Tactical Use:
* Emergency: Must be formed immediately when a cavalry charge is imminent and you are unsupported.
* Static Defense: To hold a key point when encircled.
* Risk: If the unit's morale is too low ("Shaken" or "Routed"), it may refuse to form a square and be massacred by cavalry.

The Skirmishers
The dispersed order, used by light infantry or detached elite companies.

* Characteristics:
* Protection: Difficult to hit by artillery and musketry (dispersion).
* Terrain: Ignores movement penalties in woods, villages, or uneven terrain.
* Firepower: Constant harassment, but no massive volleys.
* Vulnerability: Extremely weak in hand-to-hand combat and against cavalry.
* Tactical Use:
* Screen:** Place in front of your lines to hinder the enemy and absorb the initial fire.
* Harassment: Weaken the morale and numbers of an enemy column before an assault.
* Difficult Terrain: Fight in forests or urban areas.

Advanced Tips for Histwar

Disorder: Changing formations takes time and creates disorder. A disorganized unit fights poorly.
* Do not change formation under enemy fire* unless absolutely necessary (cavalry).
* Plan your formation changes (Column -> Line) before coming within firing range.
The Mixed Order: This is the quintessential Napoleonic tactic. Place regiments in Line in the center and two regiments in Column on the flanks.
* The line provides firepower.
* The columns protect the flanks against cavalry and provide a shock threat.
Morale and Fatigue:
* A tired unit will take longer to form a square.
* A unit whose morale drops may refuse to obey the order to form a line (it will remain in column to flee or regroup).
Artillery:
* If you see enemy artillery: Line or Skirmishers.
* If you have to cross a field under fire: **Column** (to move quickly) but by zig-zagging or using changes in elevation.

In summary: March in Column, Fight in Line, Survive in Square.
