Following Brock's death, it fought under Major-General Henry Procter at the Battle of Frenchtown in January 1813 and formed the bulk of the attacking force at the Siege of Fort Meigs in April 1813. It then formed part of the crew of the British naval squadron which was defeated at the Battle of Lake Eriein September 1813 and faced defeat again at the Battle of the Thames in October 1813.
