There were also resistance movements fighting against the Allied invaders. In Italian East Africa, after the Italian forces were defeated during the East African Campaign, some Italians participated in a guerrilla war against the British (1941–1943). The German, Nazi resistance movement ("Werwolf") never amounted to much. The "Forest Brothers" of Estonia, Latvia and Lithuania included many fighters who operated against the Soviet occupation of the Baltic States into the 1960s. During or after the war, similar anti-Soviet resistance rose up in places like Romania, Poland, Bulgaria, Ukraine, and Chechnya.
