From Thriller Picture Library #347, January 1961.
It is early 1945 and the Germans are near collapse. It is learned that a noted tank battalion commander, currently out of favor with Hitler, might be brought back into command which would lengthen the war. He is currently the commandant of a POW camp in Poland. The British have a plan to keep him from retaking control of the mechanized forces but it needs John Steel to let himself be taken prisoner in that region to get it started.
