Vilna Ghetto
Glick managed to flee when the Vilna Ghetto was being liquidated in October 1943, but got captured. Later he was deported to a concentration camp in Estonia. During his captivity he continued to compose songs and poems. In July 1944, with the Soviet Army approaching, Glick escaped. He was never heard from again, and was presumed captured and executed by the Germans (reportedly in August 1944).
