Ypres, Flanders. The BEF had held Ypres, as they continued to do until the end of the war despite repeated German assault; the Allies also held a salient extending 6 miles into German lines. The cost had been huge on both sides. British casualties were reported at 58,155, mostly pre-war professional soldiers, a loss the British could ill-afford. French casualties were set at around 50,000, and German losses at 130,000 men.
