The case of Pat Tillman, millionaire football player turned volunteer U.S. Army Ranger who died under fire in Afghanistan, became the stuff of myth. And as a Washington Post investigation has found, the military did what it could to keep it that way.

An excerpt from part one of In The Kill Zone: The Unnecessary Death of Pat Tillman:

Dozens of witness statements, e-mails, investigation findings, logbooks, maps and photographs obtained by The Washington Post show that Tillman died unnecessarily after botched communications, a mistaken decision to split his platoon over the objections of its leader, and negligent shooting by pumped-up young Rangers -- some in their first firefight -- who failed to identify their targets as they blasted their way out of a frightening ambush.

The records show Tillman fought bravely and honorably until his last breath. They also show that his superiors exaggerated his actions and invented details as they burnished his legend in public, at the same time suppressing details that might tarnish Tillman's commanders.

Army commanders hurriedly awarded Tillman a posthumous Silver Star for valor and released a nine-paragraph account of his heroism that made no mention of fratricide. A month later the head of the Army's Special Operations Command, Lt. Gen. Philip R. Kensinger Jr., called a news conference to disclose in a brief statement that Tillman "probably" died by "friendly fire." Kensinger refused to answer questions.

Friends and family describe Pat Tillman as an American original, a maverick who burned with intensity. He was wild, exuberant, loyal, compassionate and driven, they say. He bucked convention, devoured books and debated conspiracy theories. He demanded straight talk about uncomfortable truths.

After his death, the Army that Tillman served did not do the same.

Here's part two: In The Kill Zone: Managing Facts:

An April 30 Army news release about Tillman's death was a  stirring tale and fitting eulogy for the Army's most famous volunteer in the war on terrorism, a charismatic former pro football star whose reticence, courage and handsome beret-draped face captured for many Americans the best aspects of the country's post-Sept. 11 character.

It was also a distorted and incomplete narrative, according to dozens of internal Army documents obtained by The Washington Post that describe Tillman's death by fratricide after a chain of botched communications, a misguided order to divide his platoon over the objection of its leader and undisciplined firing by fellow Rangers.

The Army's public release made no mention of friendly fire, even though at the time it was issued, investigators in Afghanistan had already taken at least 14 sworn statements from Tillman's platoon members that made clear the true causes of his death. The statements included a searing account from the Ranger nearest Tillman during the firefight, who quoted him as shouting "Cease fire! Friendlies!" with his last breaths.

Army records show Tillman fought bravely during his final battle. He followed orders, never wavered and at one stage proposed discarding his heavy body armor, apparently because he wanted to charge a distant ridge occupied by the enemy, an idea his immediate superior rejected, witness statements show.

But the Army's published account not only withheld all evidence of fratricide, but also exaggerated Tillman's role and stripped his actions of their context. Tillman was not one of the senior commanders on the scene -- he directed only himself, one other Ranger and an Afghan militiaman, under supervision from others. And witness statements in the Army's files at the time of the news release describe Tillman's voice ringing out on the battlefield mainly in a desperate effort, joined by other Rangers on his ridge, to warn comrades to stop shooting at their own men.

The Army's April 30 news release was just one episode in a broader Army effort to manage the uncomfortable facts of Pat Tillman's death, according to internal records and interviews.
