This sailor earned the Medal of Honor for saving his crew from an Israeli attack

The officers of the USS Liberty were sunbathing on the decks of their ship on June 8, 1967, just outside of Egypt's territorial waters. Not too far away, Egypt was in the middle of the Six Day War with the Israelis, who would occupy the Sinai Peninsula by the war's end.

The peaceful day aboard the intelligence-gathering ship was destroyed when Israeli Mirage and Mystere jets tore through the air – and dropped ordnance that ripped through the Liberty's hull.

Commander William McGonagle was severely wounded as the Israelis fired rockets, dropped napalm on the bridge, and then strafed his ship. He still managed to call his crew to quarters and take command of the Liberty from the bridge. The ship was on fire, men were dead and wounded, and McGonagle himself was burned by napalm and losing blood.

The Liberty was not a warship but a lightly-armed, converted freighter — a holdover from World War II. Her mission was to collect signals intelligence and radio intercepts on the war between the Arabs and Israelis but not to get involved in the fighting or violate Egyptian sovereignty.

With his ship still in range of the U.S. 6th Fleet, Cmdr. McGonagle radioed the USS Saratoga, which sent 12 fighters to assist. Those fighters were recalled on orders from Washington. The Israeli fighters eventually let up and disappeared on their own. But that wasn't the end of the attack. When they were gone, three Israeli torpedo boats opened up on the American ship and blew a 40-foot hole in the Liberty's hull.

The armaments on the USS Liberty were totally outmatched. The ship was carrying only four .50-caliber machine guns, a far cry from the Egyptian ship Israelis claim shelled the coastline that morning. The Liberty was a sitting duck.

Of the ship's 294 men, 34 were killed in the attack and 171 were wounded.

With his ship burning and flooded, McGonagle directed the maneuvering of his ship for 17 hours while critically wounded. He refused medical treatment until he was convinced more critically wounded members of his crew were treated. He didn't give up command until the Liberty encountered a U.S. destroyer.

For his gallantry and determination, McGonagle was awarded the Medal of Honor.

Israel maintained that its attack on the Liberty was a mistake, that the planes were looking for an Egyptian ship, the El Quseir. Some find this troublesome, considering the El Quseir was a very different size than the Liberty and had a very different profile. Still, The IDF's own inquiry says the Israeli Chief of Naval Operation did not know the Liberty was in the area. The captains of the torpedo boats maintained that closer identification was impossible because the Liberty was "enveloped in smoke."

McGonagle's official account of the incident corroborates the Israeli account, but the crew of the Liberty aren't so certain. A 2002 BBC Documentary includes interviews with the Liberty's crew, Israeli officials, and even Robert McNamara, the U.S. Secretary of Defense at the time.

"I was never satisfied with the Israeli explanation," then-Secretary of State Dean Rusk said of the Liberty Incident "Their sustained attack to disable and sink Liberty precluded an assault by accident or some trigger-happy local commander. ... I didn't believe them then, and I don't believe them to this day. The attack was outrageous."

There are numerous conspiracy theory-related sites, some even run by Liberty crewmembers, that call into question some of the actions of the Israeli forces and of the orders from Washington. Some of these theories include:

• The Liberty was attacked to keep the U.S. from knowing about Israel's upcoming attack on Syria.

• Trying to draw the U.S. into a greater anti-Arab war.

• Hiding Israeli war crimes (alleged massacres of Egyptian POWs).

• Israelis using unmarked aircraft.

• Torpedo boats machine gunning life rafts.

• Jamming radio signals meant that Israel knew the frequency the ships would be on– and thus knew they were American.

Official accounts (including from McGonagle) maintain that the Israeli torpedo ships halted mid-attack and offered assistance once the identity of Liberty was ascertained. The Americans politely declined.

Though Israel has apologized for the incident and paid reparations to the sailors' families, many among the crew of the Liberty believe the U.S. still downplays the attack on their ship to kowtow to their longtime ally.
