In 1945, Anglo-American Soviet troops began to enter the concentration camps and soon found corpses and bones of the Jewish people. The soldiers had also found many survivors, most of which were dying from starvation and disease. After this liberation, the survivors were fearful of building a new life in Europe because of the anti-Semitism that was still occurring. Thousands of homeless Holocaust survivors migrated westward to other European territories liberated by the western Allies. There they were kept in hundreds of refugee centers and displaced persons camps in Germany. The United Nations Relief and Rehabilitation Administration and the armies of the United States, Great Britain, and France ran these camps. In 1944 the Jewish Brigade Group was formed. Together with former partisan fighters displaced in central Europe, the Jewish Brigade Group created the Brihah, an organization that tried to assist the departure of Jewish refugees from Europe to Palestine. Jews that were already living in Palestine had organized illegal immigration by ship. British authorities cut off and turned back most of these ship. In 1947 the British forced the ship Exodus 1947 to return to Germany. Once the State of Israel had been established in 1948, Jewish displaced persons and refugees began pouring in to Israel. By 1953 almost 170,000 Jewish displaced persons and refugees had immigrated to Israel. Due to President Harry Truman's new restrictions on immigration to the US, 41,000 displaced persons immigrated to the United States and about 28,000 were Jews. Also, In 1948, the US Congress passed the Displaced Persons Act, which provided approximately 400,000 US immigration visas for displaced persons between January 1, 1949, and December 31, 1952. Of the 400,000, 68,000 were Jews.
