"In Germany Ascendant, Buttar examines the critical year of 1915, when Germany launched the great Gorlice-Tarnow Offensive, lead by Field Marshal Mackensen. The move, which started as a minor German operation to relieve their Austro-Hungarian allies, ultimately resulted in the utter collapse of Russian forces from all of Poland and Gallacia, and came tantalizingly close to knocking Russia out of the war altogether. Next the Germans led the invasion of Serbia, leading Britain and France to intervene with ground troops, an operation that ultimately failed." -- from backcover.
