The Manx Garrison comprised the paid soldiers who garrisoned the Island's forts under the Lords of Mann, primarily Castle Rushen and Peel Castle, with smaller detachments at Douglas, Ramsey, and Derby Fort on Langness. The garrison soldiers also performed civil duties and acted as turnkeys, with their arms and provisions supplied at the Lord's expense; after the Revestment of 1765, these functions passed to British troops and civilian constables.
