Russia had lost a great deal of territory to Germany and Austria in 1915, and they wanted to gain it back. Russian General Alexei Brusilov put together a plan in April 1916 to launch a major offensive against Austria. It ended up being Russia's greatest feat of arms during World War I, and among the most deadly military offensives in world history. Brusilov hoped to take pressure off France and Britain and hopefully knock Austria out of the war. The plan was to attack along a broad front, preventing the Austrians from using reserves and minimizing the distance between Russian and Austrian lines. The result of the Brusilov Offensive was a terrible Russian blow against Austria-Hungary, which took 1,000,000 casualties. Russia could not hold onto its land gains, but it demonstrated its military capability on the eve of the Bolshevik Revolution.
