Cannons were soon used at sea, with ships being used as firing platform. Small guns projecting quarrels or lead pellets were used at the 1340 Battle of Sluys, and in the French defense of Tournai in August 1340. Edward III used similar weapons at the Battle of Crécy in 1346, and in the Siege of Calais in 1347. "Ribaldis" were first mentioned in the English Privy Wardrobe accounts during preparations for the Battle of Crécy between 1345 and 1346.
