A company was present at the Battle of York but was able to play little part, as they were misdirected by the commander of the Upper Canadian militia. Another company suffered severe losses at the Battle of Fort George, trying to prevent American troops landing on the lake shore to outflank the fort. Yet another company was present at the Battle of Sackett's Harbor, where troops under Prevost and Baynes withdrew after failing to drive American troops from buildings and hastily constructed defences.
