Submarines were uninviting enough, with dank, claustrophobic conditions and little hope of escape if disaster struck, and the relatively shallow waters of the Baltic only compounded the dangers. That's where Soviet submariner Viktor Korzh served, hunting and sinking German shipping. His memoir unfolds as a heart-pounding series of non-stop action, sonar pings, depth-charge concussions, and constant underwater peril. Somehow Korzh and his comrades survived their frightful ordeal and witnessed the victory over the Germans.
