The men of the Bulgarian 9th Pleven Infantry Division, dug into the rocky heights above Lake Doiran in the spring of 1917, called it the Boris position, after the prince in whose name they thought they were fighting. The valley runs west-southwest from the lake toward the Vardar River, between bare hills on what is now the border between Greece and North Macedonia. From late February through May, three British divisions and their supporting Greek and French units threw themselves at the Bulgarian line. They were stopped both times. The British losses ran to 12,000 killed, wounded, and captured, of whom the Bulgarian defenders buried 2,250 on the field. The Pleven Division lost about 2,000 men, half of them to disease and wounds rather than combat. The front then went quiet for sixteen months. It would not break here until September 1918, in the Third Battle of Doiran, when the war was already ending elsewhere.
