By the end of May 1940, the best-equipped French armies had been sent north and lost in Fall Gelb and the evacuation from Dunkirk, which cost the Allies 61 divisions. Weygand was faced with the prospect of defending a 965 km (600 mi) front from Sedan, along the Aisne and Somme rivers to Abbeville on the Channel, with 64 French divisions. The 51st (Highland) Infantry Division and a few British divisions being sent to French ports south of the Somme to form the "2nd BEF" were the only British contribution.
