Lawrence Colburn returned to My Lai on Saturday and found hope at the site of one of the most notorious chapters of the Vietnam War.

On the 40th anniversary of the massacre of up to 500 unarmed Vietnamese villagers, the former helicopter gunner was reunited with a young man he rescued from rampaging U.S. soldiers.

On March 16, 1968, Colburn found 8-year-old Do Ba clinging to his mother's corpse in a ditch full of blood and the bodies of more than 100 people who had been mowed down. Nearly all the victims were unarmed women, children and elderly.

Seymour Hersh, the journalist who exposed the massacre, said he sees parallels between My Lai and a more recent story that he has he reported on, the 2005 images of torture from the Abu Ghraib prison in Iraq. But he says the public furor unleashed by My Lai was far greater.
