The Siege of Calais occurred when an English army under the command of King Edward III of England successfully besieged the French garrison of Calais. It was an important engagement early in the Edwardian phase of the Hundred Years' War.
During 1346 the English army attempted to take Calais by assaulting it and although the English had surrounded the port, their siege lines were not tight and the French were still able get supplies into Calais usually by sea. Once it became clear to Edward that assault was unlikely to be successful he tighten the investment including the sea approaches. This tactic proved successful and due to the lack of provisions the town surrendered on 3 August 1347.
