From the review:
In 1812 – The Invasion of Canada, players take on one of the roles of the major factions that took part in the War of 1812. On the British side these are represented by the British Regulars (Redcoats), Canadian Militia and Native Americans; and the American Regular Army and American Militia comprise the American players. Players for each side will cooperate with each other in order to plan and conduct their campaigns. Each side will attempt to capture Objective Areas on the map. When a truce is called, the side that controls the most enemy Objective Areas wins.
