The book explains how these brave men battled Taliban forces back into the stronghold city of Mazar-i-Sharif, only to find themselves outnumbered by attackers posing as POWs.

Horse Soldiers will work from a non-fiction novel by Doug Stanton, which pit a small band of Special Forces soldiers against Taliban forces on the ground in Afghanistan.
