The unit nevertheless served as infantry during the Battle of Fort George, where they suffered a number of losses. Together with 100 men of the 1st Lincoln Militia, a company of the Royal Newfoundland Fencibles and two companies of the Glengarry Light Infantry, the (then) 27 men of the unit attempted to repulse the initial American landing at the mouth of Two Mile Creek () near the property of James Crooks. Under fire from American gunboats (which included built by Crooks and his brother William two years earlier as the trading schooner "Lord Nelson"), the defenders put up a stiff defence for some 15 minutes, the two sides firing at each other from as little as before the superior numbers of attackers made a British withdrawal inevitable.
