In the predawn hours of March 4, 2002, just below the 10,000-foot peak of a mountain in eastern Afghanistan, a fierce battle raged. Outnumbered by Al Qaeda fighters, Air Force Combat Controller John Chapman and a handful of SEALs struggled to take the summit in a desperate bid to find a lost teammate.
