Siege

The French siege proved futile as English reinforcements under Lieutenant of Calais Sir Richard Aston arrived with the Calais garrison to counterattack and lift the siege.^[2] Although surprised by the English attack the French troops manned the trenches, but the Genoese crossbowmen had no bolts and St. Pol's army suffered losses from English archers.^[2] The first to flee were the Flemings, quickly followed by the French and Genoese.^[2] Waleran III escaped with remnants of his army, but most were either killed or captured. The English captured all the French artillery, four standards, 60-80 prisoners including Jean de Hangest.^[2]
