He was exhausted, but he wanted to talk to his daughter, and the only way to do that in Fallujah was to write a letter. "This war is not like the big war—there are no big sweeping maneuvers with hundreds of tanks pouring over the border and so forth," Army Maj. Michael Mundell told his 17-year-old, Erica (nicknamed "Eddie"), on Friday, Oct. 27, 2006. "It's a fight of 10 man squads in the dark, of ambushes and snipers and IEDs. When I go out to fight, it's usually with less than 20 men ... And I go out to fight almost every day."

The pace, he admitted, was punishing.

"We are weary, Eddie, so very weary. I can't tell you how bone tired I am. There are times when we get back in and ... it is all I can do to drag myself from the truck and stagger up here to take off all the junk I gotta wear ... " His tone briefly brightened as he thought of Erica's life back home, where she was a senior at Meade County High School in Brandenburg, Ky.: "Tell all of your friends and your teachers that I said hello from Fallujah. I am doing well and our battalion is considered the best in the brigade. We are fighting the enemy and hopefully winning, though that is difficult to measure." He signed off with a pledge: "Never forget that your daddy loves you more than anything and that I will be home soon." Mundell could not keep that last promise. At a quarter to 2 on the afternoon of Friday, Jan. 5, 2007, he was killed by an IED while on patrol in Fallujah; the casket was closed at his funeral in Kentucky.

Never forget that your daddy loves you: As a soldier, husband, father and casualty of war, Michael Mundell is one of at least 3,230 Americans who have died in the struggle for Iraq. He was 47 years old and left behind his wife, Audrey, and four children, all under 18. By itself, Mundell's story is sad but familiar, even predictable. Wars have always made women widows and children orphans. When Mundell was laid to rest in a hillside cemetery in Irvington, Ky., he joined the solemn company of America's fallen warriors—men and women who become objects of veneration, commemorated, in Lincoln's words, as the "honored dead" who "gave the last full measure of devotion." They are garlanded and buried beneath white marble, revered but silenced.

Yet they still have stories to tell, stories that bear hearing, and remembering. In letters and journals and e-mails, the war dead live on, their words—urgent, honest, unself-conscious—testament to the realities of combat. What do they have to say to us? This special issue of NEWSWEEK is an attempt to answer that question. We have collected the correspondence of American soldiers at war in Iraq, accounts written not for the public but for those they loved—wives, husbands, children, parents, siblings. Each of the warriors whose words are excerpted here died in the line of duty. Each of their families chose to share their stories with us, and with you. "It's become very important to me that these soldiers and Marines are viewed as individuals with lives, dreams, experiences and families," says Terri Clifton, whose son, Marine Lance Cpl. Chad Clifton, was killed by a mortar in Anbar province. "They aren't cardboard cutouts in shades of red, white and blue."

No matter where one stands on the decision to invade or on the conduct of the conflict over the last four years, the Iraq War is indisputably a curious thing. For the first time in the experience of any living American, we have sent an all-volunteer force overseas to advance our interests for a prolonged period, and virtually nothing has been asked of the vast majority of those who do not have loved ones in the line of fire. The bargain is hardly fair. If we take the president at his word, the men and women of the armed forces are fighting and dying over there so that you and I will not have to face mortal danger over here.
