      In World War I, from October to December 1916, Serbian forces were caught between German and Bulgarian forces. After losing the Serbian mainland, the Serbian army continued to fight back on the few remaining islands of Koruk. Serbs were massacred, and relatives of Serbian women stopped by the bodies to autopsy them in search of their immediate relatives.

　Serbia was a British ally and resisted Austro-Hungarian attacks early in World War I. In October 1915, Serbia was overrun in October 1916 by a central alliance of Austrian, German, and Bulgarian forces. The Serbian army retreated through the mountains of Montenegro into Albania, losing about 200,000+ Serbian soldiers in the winter snows. The surviving Serb soldiers took refuge on the island of Corfu to regroup.

　On December 6, 1916, when the Bulgarians launched their attack after a heavy artillery barrage, French and British units repulsed several Bulgarian attacks. Lacking sufficient artillery, the French and British forces retreated to Salonika in northeast Greece. The Germans prevented the Bulgarians from advancing into Greece, and in 1916, they built a fortification line in the hills around Salonika. 1916, French, Serbian, Russian, and Italian troops captured the western part of the front, and Serbian troops occupied Monastir. 1918, September, Allied troops attacked Do Iran and broke through the front line. The Bulgarian army withdrew after a hard struggle against the Allied forces. The Bulgarian army was defeated, liberated Serbia, and rallied with strategic exposure of the Austrian army and Turkey. Bulgaria signed the Allied armistice on September 28, 1918.
