Throughout World War II and in the aftermath, persecuted Jews tried to find their way into the British Mandate of Palestine, often deemed illegally by British authorities, as the Royal Navy tried to stop them. On December 14, 1945, the ship Hannah Senesh, carrying 252 refugees, evaded British patrols and beached itself at Nahariya in Palestine. The passengers came ashore via a rope bridge and evaded capture. Large-scale Jewish immigration to Palestine increased regional tensions, which would explode into war in 1948 with the invasion of the newly established State of Israel by its Arab neighbors. Truman was the first US president to be faced with trouble in the Middle East; he would not be the last.
