Known as Caldwell's Rangers, after their commander, noted Loyalist and Indian trader William Caldwell. The unit was a rather small one, probably not more than fifty men. Nominally organised as two companies, they often worked in conjunction with the Indian Department and fought dispersed alongside the Indians (chiefly the Ojibwe, Wyandotte and Pottowottomi). The unit, or parts of it, fought at the Battle of Moraviantown, the Battle of Longwoods, the Battle of Lundy's Lane and in several actions on the Niagara peninsula.
