How Bin Laden met his end

The nail-biting moment, the period when absolute disaster loomed, came at the very start.

About two dozen Navy SEALs and other U.S. commandos were supposed to rope down into a Pakistani residential compound from a pair of specially modified Black Hawk helicopters in the predawn hours Monday, race into two buildings, and capture or kill Osama bin Laden. One chopper stalled as it hovered between the compound's high walls, unable to sustain its lift, and thudded into the dirt.

Half a world away in the White House Situation Room, the president and his war council crowded around a table covered with briefing papers and keyboards and watched nervously as video feeds streamed in. The Special Forces team needed a rescue chopper. Gunfire was blazing around them. No one wanted another "Black Hawk Down" debacle.

"A lot of people were holding their breath," recalled John Brennan, the president's counter-terrorism advisor.

The extraordinary drama surrounding the killing of Bin Laden encompassed the White House, the CIA and other arms of America's vast national security apparatus. The tale is part detective story, part spy thriller. But the decade-old manhunt for the Al Qaeda leader ultimately came down to a three-story building on a dirt road in the Pakistani army town of Abbottabad, north of Islamabad.

If the raid went wrong, President Obama would bear the blame. He had vetoed a plan to obliterate the compound with an airstrike. Obama wanted to be certain he had Bin Laden, and there was no guarantee that a smoking crater would yield proof. He had asked for a bolder plan, one that would allow the U.S. to take custody of Bin Laden or his body. It posed far more risk.

As reports flowed into the White House, the commando team methodically swept through the compound. Bin Laden and his family lived on the second and third floors of the largest structure, U.S. intelligence indicated. Officials said that when the commandos found him there, he was armed and "resisted." They shot him in the head and chest.

There were conflicting reports Monday about whether Bin Laden had fired at the Americans, or whether he had tried to use a woman as a human shield. His wife, who called out Bin Laden's name during the fight, was wounded in the leg during the battle and may have tried to interpose herself between the troops and her husband, but Bin Laden was not hiding behind her, a senior U.S. official said.

Within 20 minutes, the fighting had ended. In 20 more, the military had flown in a backup helicopter. The commandos questioned several people in the compound to confirm Bin Laden's identity, detonated explosives to destroy the crippled Black Hawk and then departed. As they flew off, they carried with them the bloodied corpse of the tall man with a thick beard. Continued…
