Alfred Käärmann (14 September 1922 in Hargla – 4 February 2010) was an Estonian resistance fighter, also known as Forest brother, as the Estonians call their guerrillas, and author. In 2007 he was decorated with a military honour in recognition of his service. According to the New York Times, Alfred Käärmann's life is "a monument to man's astounding ability to endure the unbearable".
Alfred Käärmann has written many books about his life as a resistance fighter. The The Girl Guide of Udumäe (Udumäe kodutütar) is about his relationship with his beloved Kleina.
In 1941 he enrolled in a local technical school, where he met and fell in love with a girl named Kleina. Conscripted by the Nazis in February 1944, Käärmann was among those who fought the Red Army until Estonia was occupied by the Soviets seven months later. At the end of the war, the Soviets conducted extensive sweeps to arrest and deport the many Estonians who had served in the German occupation Army. Wanting to avoid the fate of his brother, who was arrested and sent to Russia's most dreaded Arctic prison camp near Vorkuta, Käärmann returned home to his family farm on October 4, 1944. After a rest period, he went into hiding in the forest and joined up with fellow Estonian and Latvian Forest brothers, in the belief that it was "better to die in the forest with a weapon in your hands than in a Soviet camp".
On October 17, 1945, he was shot and wounded in a skirmish with Red Army forces. Evading capture by hiding in a swamp, then moving house to house, he was given refuge in the home of an elderly lady. Ten days later, after a message was sent via a Latvian Forest brother, a nurse from Latvia came secretly to the house and amputated his badly injured arm. After recovering from this near death experience, he was to spend another seven years in the forest. Eventually captured in 1952 by the KGB, he was sentenced to 25 years' hard labour and spent the next 15 years in various prison camps in the Ural mountains and in Mordovia, eventually being released in 1967. Returning to his home village, he found his beloved Kleina still waiting for him after 23 years.
Three months later he was given 72 hours' notice and expelled from Estonia. His internal passport was stamped "annulled", effectively making him homeless within the Soviet Union, nor was he permitted to take a job until 1972. Drifting from place to place, Käärmann was eventually permitted by the Soviet government to return to Estonia in August 1981. Again returning to his village, he found Kleina still waiting for him, where they spent 11 years together before she died in 1992.
Alfred Käärmann was elected a member of the Congress of Estonia in 1990.
