For years, Cleland believed he was the one who dropped the grenade, which led to the loss of his right arm and both legs.
Cleland retold the story in 1999 on a History Channel program. Lloyd, who was watching the show at his home in Annapolis, Md., picked up the phone and called Cleland’s office.
The story, Lloyd said, was wrong.
Lloyd said the blast was caused by another soldier’s grenade — not Cleland’s.
Lloyd said he knew because after Cleland was loaded onto the helicopter, another soldier, who had been hit by shrapnel, was crying. Lloyd tried to console the soldier, who said he had dropped the grenade.
The grenade exploded when its cotter pin had fallen out, activating the explosive, said the 57-year-old Lloyd. The soldier told Lloyd that he had straightened the pins so it would be easier to pull them when he had to throw a grenade.
Lloyd’s revelation, which checked out, changed Cleland’s life, Cleland has written. For 30 years, Cleland had blamed himself for his injuries. "
