 Stafford carried out a short march north to besiege Blaye with his advance party and perhaps 1,000 men-at-arms and 3,000 infantry of the Gascon lords.Having established the siege he left the Gascons to prosecute it and proceeded to Langon, south of Bordeaux, and set up a second siege.The Anglo-Gascon forces at both sieges could be readily supplied by ship.
