England certainly began using cannons in the early 14th century. Field artillery was deployed by King Edward III at the Battle of Crecy in 1346 but equipment which may have been an artillery piece was listed as captured on a French ship by the English, at Sluys, as early as 1340. Inverted 'keyhole' gun loops at Bodiam Castle, Cooling Castle and Westgate Canterbury have all been identified as for firing heavy handguns. These defences are dated 1380–1385. Initially used as defensive weapons primitive bombards began to be used as siege weapons in the later 14th century. Henry IV, Henry V, and James II won battles with the use of bombards. Henry V captured Harfleur with bombards in 1415. King Henry's army later came under artillery fire at the Battle of Agincourt. James II destroyed many castles with his one and a half ton cannon named "The Lion".
