The Battle of Plattsburgh; Scenario Rules and Order of Battle

The Battle of Plattsburgh, September 11th, 1814; Order of Battle and Scenario Rules
Updated and Corrected April 9th, 2017
*Note that since the land battle of Plattsburgh was called off, this is a "What if?" scenario. What if the British had started their attacks earlier?

I had errors in my original version of this scenario. All maps I have found which show troop movements do not show the main British attack which took place 4km upriver. Also, in "Land of the Free" they made a similar error. The first and third brigade as well as two cannons were crossing at Pike's Ford when the attack was called off. They would have appeared behind the American forts.



This map is from the Plattsburgh Museum, it shows British attempting to cross the river near the mouth of the river. They did attempt it, but the current was to strong. It does not show the main British attack, but it does show most of the troops' positions. The three forts had about half of their guns facing forwards, the other half covered the rear angles of the forts, they did not however, seem to cover the ends of the forts.
Here is a complete map without showing troop movements. The first and third British brigades were crossing at Pike's Ford when the attack was called off. The second brigade was preparing to attack the Lower Bridge when the attack was called off.


Here you can see the naval battle with the American defensive positions to the left. Prevost should have attacked earlier to help the fleet. In addition, better communication with the British fleet may have given them an edge. This shows the forested area in which the British first and third brigades would have emerged from. Note that the forts are not shown accurately in this map.

British / Canadian Scenario Rules

Victory Conditions; The British have to capture the 3 forts before George Downie's fleet arrives. If the forts are captured, the British are assumed to shell the anchored American fleet from shore.

1. British Infantry Shooting in Line Bonus; British / Canadian infantry get +1 to shooting rolls when in line. Militia and Indians do not get this bonus.

2. Crossing the River; The Americans took the boards off of both bridges as they withdrew. A unit which does not move at the edge of a bridge can fix half of a bridge a turn (figures from the unit not touching the bridge can still shoot).  The British had repaired the lower bridge (at the mouth of the river) right before the battle so it does not need boards added. 

3. Artillery Defence; All British artillery starts deployed behind earthworks. Gives them -2 to be hit.

American Scenario Rules

Victory Conditions; The Americans have to keep the British from capturing their forts and turning their own guns on the anchored American fleet awaiting the British fleet.

1. Linear Tactics; Whole brigades have to have the same formation except to go around terrain and other units.

2. Buck and Ball; American Regulars used “Buck and Ball”; a round shot with 3 buck shots, they get +1 to hit at close range.

3. Ammunition Problems; American troops carried less ammunition than their British counter parts, and had logistical problems becoming resupplied during battles. Any American infantry unit which rolls a double one for their shooting roll in any turn but their first turn is at half ammunition (inflicts half casualties). A unit will be at full ammunition that does not move or fire for one turn. *For this scenario, units in forts or blockhouses do not have "Ammunition Problems".

4. Chosen Men; Up to 12 men may be deployed as Chosen Men (Rifles). They roll 2D6 per 4 figures. They can form part of the skirmish screen or operate independently. They do not need to stay within 18 inches of close order units. This unit has a range of 17 inches.

5. Fort Defence; Each Fort has 24 models plus 3 or 4 cannons. The extra troops listed in the army list are combined in a unit outside the forts. Troops moving through the earthworks require ladders to climb the sides of forts and move at half speed charging through the earthworks (all British units are assumed to have ladders). Troops attempting to break a gate roll a D6 each turn they are touching the gate; on a 4,5 or 6 they have taken a hit point off the gate. A gate has two hit points, after that it is removed. Units defending forts and blockhouses get +2 morale, and -2 target modifier (General De Brigade Rules). Troops defending earthworks get +4 to melee, if defending a charge through a broken gate they get +1 to melee. Troops charging defensive positions receive no charging bonus. Up to 12 fort defenders can shoot out of any one side of the fort. If no cannons are in position to fire at oncoming troops, one cannon can be moved to the undefended side. 
Forts can't be damaged by cannon fire. 
*British Brigades can use "Sapper Rules" pg 120 in General de Brigade Rules

Each fort counts as a brigade with average command. The guns for the first two had half facing forward, the other facing backwards. Fort Scott had more of its guns facing the water I suggest that each brigade commander takes a fort to control. Each fort counts as their own brigade.
