A former Navy attorney who helped lead the military investigation of the 1967 Israeli attack on the USS Liberty that killed 34 American servicemen says former President Lyndon Johnson and his defense secretary, Robert McNamara, ordered that the inquiry conclude the incident was an accident. Retired Capt. Ward Boston said Johnson and McNamara told those heading the Navy's inquiry to conclude that the attack was a case of 'mistaken identity' despite overwhelming evidence to the contrary." Boston was senior legal counsel to the Navy's original 1967 review of the attack. He said in the sworn statement that he stayed silent for years because ... "when orders come ... I follow them." The USS Liberty was an electronic intelligence-gathering ship that was cruising international waters off the Egyptian coast on June 8, 1967. Israeli planes and torpedo boats opened fire on the Liberty. It was "one of the classic all-American cover-ups," said Ret. Adm. Thomas Moorer, a former Joint Chiefs of Staff chairman who spent a year investigating the attack as part of an independent panel he formed with other former military officials. The panel also included a former U.S. ambassador to Saudi Arabia, James Akins. David Lewis of Lemington, Vt., was on the Liberty when it was attacked. In an interview, he said Israel had to know it was targeting an American ship. He said a U.S. flag was flying that day and Israel shot it full of holes. The sailors on the ship, he said, quickly hoisted another American flag, a much bigger one, to show Israel it was a U.S. vessel.
