train to ports on the Mediterranean Sea, where ships brought them to Palestine. Most of the ships had names such as Lo Tafchidunu ("You can't frighten us") and La-Nitzahon ("To the victory") designed to inspire and rally the Jews of Palestine. Some were named after prominent figures in the Zionist movement, and people who had been killed while supporting Aliyah Bet. More than 70,000 Jews arrived in Palestine on more than 100 ships. American sector camps imposed no restrictions on the movements out of the camps, and American, French, and Italian officials often turned a blind eye to the movements. Several UNRRA officials (in particular Elizabeth Robertson in Leipheim) acted as facilitators of the emigration. The British government vehemently opposed the movement, and restricted movement in and out of their camps. The British set up armed naval patrols to prevent immigrants from landing in Palestine. History Over 100,000 people attempted to illegally enter Mandatory Palestine. There were 142 voyages by 120 ships. Over half were stopped by the British patrols. The Royal Navy had eight ships on station in Palestine, and additional ships were tasked with tracking suspicious vessels heading for Palestine. Most of the intercepted immigrants were sent to internment camps in Cyprus: (Karaolos near Famagusta, Nicosia, Dhekelia, and Xylotymbou. Some were sent to the Atlit detention camp in Palestine, and some to Mauritius. The British held as many as 50,000 people in these camps (see Jews in British camps on Cyprus). Over 1,600 drowned at sea. Only a few thousand actually entered Palestine. The pivotal event in Ha'apala program was the incident in 1947. Exodus was intercepted and boarded by a Royal Navy patrol. Despite significant resistance, passengers from Exodus were forcibly returned to Europe, and eventually put in camps in Germany. This was publicized, to the great embarrassment of the British government. One account of Aliyah Bet is given by journalist I. F. Stone in his 1946 book Underground to Palestine, a first-person account of traveling from Europe with displaced persons attempting to reach the Jewish homeland. Some 250 American veterans, including Murray Greenfield (of the ship Hatikva), from World War II volunteered to sail ten ships ("The Jews' Secret Fleet") from the United States to Europe to load 35,000 survivors of the Holocaust (half of the illegal immigrants to Palestine), only to be deported to detention camps on Cyprus.
