By the evening of June 8, the Liberty -- which was armed with only a handful of .50-caliber machine guns -- was nearly sunk. A barrage of torpedoes slammed into the ship's hull as Israeli aircraft dropped napalm and strafed her deck repeatedly. The attack lasted two hours, according to Bowen.
Dozens of Americans were dead, and the questions of why and how hung over the survivors, and public and defense officials in the wake of the attack and the brief war.
Barely 20 days later, the Navy said it had an answer to what had happened or, rather, a partial one: The Liberty was doing its duty, the attack was unprovoked, Israel had "ample time" to identify the ship, but the U.S. could not identify the reason for the attack, according to a 1967 Department of Defense press release. The U.S. government has never publicly blamed Israel for anything other than an accident.
The Liberty's survivors say that Israel had to have known that the vessel was American -- flying an American flag -- and the attack was made without warning or justification.
Frank Spicher, a 56-year-old Maryland resident, was at Arlington on Wednesday in remembrance of his father, Petty Officer 2nd Class John C. Spicher, a Navy postal clerk who was killed during the attack.
Though the younger Spicher was approaching two years old at the time of the attack, he says his first memory was of burying his father at Arlington; he was on his grandfather's shoulders, his small head sliding under the canopy that protected the ceremony from the rain that day.
"For 10 or 12 years, the last thing that I heard when I fell asleep at night was this crack, and I had no idea what it was," he said. "Years went by before I realized, when I had seen it on TV on Memorial Day, it was actually a 21-gun salute somewhere in the cemetery."
