The French had suffered 5,000 casualties and up to 49,000 troops went into captivity, along with several hundred guns and machine-guns; German casualties were 1,100–5,000 men. The garrison had withstood bombardment by heavy and super-heavy artillery, air raids and infantry attacks for fifteen days, longer than any other besieged fortress in Belgium or France, leaving the German 2nd Army short of troops as it pursued the Franco-British Armies southwards towards the Marne.
