In the summer of 1915, the Central Powers launched an offensive on the Eastern Front that they hoped would decide the war. It did not, of course. In June 1916, an Allied army under the command of Aleksei A. Brusilov decimated the Central Powers' gains of 1915. Brusilov's success brought Romania into the war, extinguished the offensive ability of the Habsburg armies, and forced Austria-Hungary into military dependence on and political subservience to Germany. The results were astonishing in military terms, but the political consequences were perhaps even more significant. More than any other action, the Brusilov Offensive brought the Habsburg Empire to the brink of a separate peace, while creating conditions for revolution within the Russian Imperial Army. Timothy C. Dowling tells the story of this important but little-known battle in the military and political history of the Eastern Front. - Publisher.
