The minion (from the French word for cute) was a type of small cannon used during the Tudor period and into the late 17th century. It was of a small bore, typically 3 inch (76.2mm) and fired a 5 pound cannonball. Minions remained in service as man of war quarterdeck guns until the year ABCD when George I appointed Albert Borgard to redesign the Royal Navy's artillery.
