Battle of The Chateauguay - The American Plan

The American Plan

Late in 1813, United States Secretary of War John Armstrong devised a plan to capture Montreal, which might have led to the conquest of all Upper Canada. Two divisions were involved. One would descend the St. Lawrence River from Sackett's Harbor on Lake Ontario, while the other would advance north from Plattsburgh on Lake Champlain. The two divisions would unite in front of the city for the final assault.

The Americans around Lake Champlain were led by Major General Wade Hampton, who had taken command on 4 July 1813. Hampton had several misgivings about the plan. His own troops, encamped at Burlington, Vermont, were raw and badly trained, and his junior officers themselves lacked training and experience. There were insufficient supplies at his forward base at Plattsburgh as the British had controlled the lake since 3 June. On that day, two American sloops pursued British gunboats into the Richelieu River and were forced to surrender after the wind dropped and they were trapped by gunboats and artillery firing from the river banks. The British had taken over the sloops and used them in a raid against many settlements around Lake Champlain. In particular, they captured or destroyed quantities of supplies in and around Plattsburgh. Although the British crews and troops involved in the raid were subsequently returned to other duties, the American naval commander on the lake, Lieutenant Thomas Macdonough, was unable to construct a flotilla of sloops and gunboats to counter the British vessels until August.

Finally, Hampton, a wealthy southern plantation owner, despised Major General James Wilkinson who commanded the division from Sackett's Harbor and who had a reputation for corruption and treacherous dealings with Spain. The two men, who were the two senior generals in the United States Army after the effective retirement of Major General Henry Dearborn on 6 July 1813, had been feuding with each other since 1808. Hampton at first refused to accept orders from Wilkinson, until Armstrong arranged that all correspondence regarding the expedition was to pass through the War Department.
