ブルシーロフ攻勢
Although the Brusilov Offensive was initially successful, it slowed down considerably. An inadequate number of troops and poorly maintained supply lines hindered Brusilov's ability to follow up on the initial victories in June. The Brusilov Offensive is considered to be the greatest Russian victory of the First World War. Although it cost the Russians half a million casualties, the offensive successfully diverted substantial forces of the Central Powers from the Western front, and persuaded Romania to join the war, diverting even more Central Powers forces to the East.
