Moyne Assassination
In 1944, the leaders of Lehi decided to assassinate Lord Moyne, the British Minister of State for the Middle East. Yitzhak Shamir originally planned the assassination, and chose Eliyahu Bet-Zuri and Eliyahu Hakim to carry it out. Cohen was picked to train the two assassins for their mission, and traveled from Tel Aviv to spend several weeks training the two in Jerusalem. After the assassination, Cohen became "a legend" within Lehi, and a reward was once again offered for his capture.
After the attack, Cohen was also involved in planning an attack on Harold MacMichael that failed. Shortly thereafter, Cohen was apprehended by the British and sent to a detention centre in Africa. On July 6, 1948, the British released Cohen, along with a large number of other detainees in response to Israel's independence.
