Tomorrow is the 60th anniversary of D-Day. Our veterans who participated were the bravest of the brave, as are the troops in Afghanistan and Iraq. Take a moment tomorrow to remember the sacrifice these men and women made:

"Now and then, construction work unearths bones and skeletons from soldiers. This happens fairly often," said Fritz Kirchmeier, a spokesman for the German organization that tends the 80,000 graves for German soldiers in Normandy.

Casualty estimates for Allied forces vary, but range from

2,500 to more than 5,000 dead on D-Day. Adding to the confusion is that D-Day books and histories often count wounded, missing and troops taken prisoner.

On its Web site, the D-Day Museum in Portsmouth, England, says an estimated 2,500 Allied troops died. The U.S. Army Center of Military History in Washington, D.C., numbers 6,036 American casualties, including wounded and missing. The Heritage Foundation in Washington estimates 4,900 dead.

"It's very difficult to get accurate figures. People get buried. Bodies disintegrate. Evidence of the deaths disappeared. People drowned," said John Keegan, author of "Six Armies in Normandy: From D-Day to the Liberation of Paris."

He estimates 2,500 Americans and 3,000 other Allied troops died on D-Day.

Peggy Noonan says it better than anyone.
