The Eiserne Division ("Iron Division") was the name of an anti-communist military formation made up of German volunteers that took part in the Latvian War of Independence in the Baltic States in 1919. It was the best-known Freikorps formation in the Baltic States. The unit was deployed against Soviet Russia-backed Soviet Latvia, and later fought against the army of the Republic of Latvia after a defection to Russian monarchist command. The division, which at times numbered up to 16,000 men, was disbanded at the beginning of 1920 due to mutiny.
