The controversy revolves around Operation Anaconda, a March 2002 attempt to surround and destroy a large Al-Qaeda force. It took place in eastern Afghanistan and cost the lives of eight Americans, seven of them on Takur Ghar. Chapman was among the dead. Using Predator drone footage and other evidence, the Air Force has argued that a SEAL Team 6 unit mistakenly left him for dead while retreating under heavy fire. Afterward, the Air Force claims, Chapman fought on for an hour, badly wounded and alone, before Al-Qaeda militants killed him as he provided cover for an approaching helicopter.

The SEALs, however, reject the claim that Chapman was alive when they fled. “The SEALs did not want to be told—officially—that they left a comrade on that mountain alive,” says a former defense official, who, like most sources mentioned in this story, requested anonymity for security reasons or to describe sensitive high-level discussions about members of classified units.
