Battle of Saint-Omer

The battle of Saint-Omer was a large action fought in 1340 as part of King Edward III's summer campaign against France launched from Flanders in the early stages of the Hundred Years' War. The campaign was launched in the aftermath of the battle of Sluys but proved far less successful for the English than this previous action and resulted in little change of situation for either side. The battle of Saint-Omer was the culmination of the northern fork of Edward's campaign and resulted in a tactical stalemate but forced a strategic withdrawal for the Anglo-Flemish forces.
