Captain Runchey's Company of Coloured Men fought at Queenston Heights on 13 October 1812, though Runchey did not participate and Lieutenant James Cooper of the 2nd Lincoln Militia took command instead. There are no surviving records that show Runchey ever commanded his Company on the battlefield. Runchey resigned by 24 October 1812, though his son, George, remained with the unit. The Company went on to participate in battles such as Fort George and the Siege of Fort Erie and, after the war ended, disbanded on 24 March 1815.
