When I was writing my first book, 'In Harm's Way,' I witnessed the sense of sacrifice that those WWII veterans possessed. I was surprised that sometimes their grandchildren hadn't talked to them about the historic events of that night in July 1945, when the USS Indianapolis went down.

When I look at Lake Michigan each July, I imagine the men of the Indianapolis visible on the horizon; dark heads, struggling arms, a cry and whirl of a world being remade. I feel an overwhelming sense of sadness, accompanied by a desire to yell out that they will be rescued.

'Horse Soldiers' is the untold story of how a small band of U.S. Special Forces soldiers secretly entered Afghanistan in 2001, just five weeks after September 11, saddled up on horses, and rode to an improbable victory against a vastly larger Taliban and Al Qaeda army.

Of all the places I've been while talking to audiences about the U.S. Army's 5th Special Forces Group and their story in Afghanistan, one of the most rewarding was an appearance before the 5th Group soldiers themselves at Ft. Campbell, their home, and the place from which they had launched their historic mission in Afghanistan in 2001.

Instead of large-scale occupations, we should rely on small units of Special Forces who have proved it's infinitely more effective to work with a country's soldiers and citizens at eye level.
