Italy joined the Allies in May, but the rest of the year favored the Central Powers. In August the Germans pushed the Russians out of Poland, while in October the Bulgarians joined the War and helped defeat Serbia. The Allies landed in officially neutral Greece in an attempt to save the Serbs, but were only able to rescue part of their fleeing army.
