On June 8, 1967, the fourth day of the Six-Day War, the Israeli high command received reports that Israeli troops in El Arish were being fired upon from the sea, presumably by an Egyptian vessel, as they had a day before. The United States had announced that it had no naval forces within hundreds of miles of the battlefront on the floor of the United Nations a few days earlier; however, the USS Liberty, an American intelligence ship under the dual control of the Defense Intelligence Agency/Central Intelligence Agency and the Sixth Fleet, was assigned to monitor the fighting. As a result of a series of United States communication failures, whereby messages directing the ship not to approach within 100 miles were not received by the Liberty, the ship sailed to within 14 miles off the Sinai coast.
