When war was declared on June 18, 1812, Captain Benjamin Forsyth's company of the regiment was stationed in New York City. In July 1812, Forsyth led his company to Sacketts Harbor, New York from which, on September 20–21, 1812, he, his company and supporting militia attacked British stores at Gananoque, Upper Canada. Forsyth surprised the Canadian militiamen and was able to capture muskets, ammunition and prisoners. Forsyth's party set fire to stores they could not carry and returned safely to Sackets Harbor from the raid. Forsyth's losses were one man killed and one wounded.
