Civil War breakout

"Civil War, 1863. Virginia. Union soldiers Colonel Thomas Rose and Major A. G. Hamilton were captured by the Confederate Army and taken to Libby Prison--one of the most horrific prisons ever run. Few ever made it out of the overcrowded, vermin-infested prison alive. But neither fear, nor darkness, nor squealing rats could keep Rose and Hamilton from freedom. They and other POWs would fight against the odds to attempt the largest prison escape in American history"--Provided by publisher.
