Medieval War Hammer. A particular use of the maul was by archers in the 15th and 16th centuries. At the Battle of Agincourt, English longbowmen are recorded as using lead mauls, initially as a tool to drive in stakes but later as an improvised weapon. Other references during the century (for example, in Charles the Bold's 1472 Ordinance) suggest continued use. They are recorded as a weapon of Tudor archers as late as 1562.
