Brusilov offensive

1916 Russian offensive during World War I

The Brusilov offensive (Russian: Брусиловский прорыв, romanized: Brusilovskiĭ proryv, lit. 'Brusilov's breakthrough') of June to September 1916 was the Russian Empire's greatest feat of arms during World War I and among the most lethal offensives in world history. The historian Graydon Tunstall called the Brusilov offensive the worst crisis of World War I for Austria-Hungary and the Triple Entente's greatest victory, but it came at a tremendous loss of life. The victory contributed to a morale upsurge among the Russian troops.
