The Tunnellers of Holzminden (with a side-issue)

An eyewitness account describes life inside a prisoner-of-war camp and the meticulous planning, excavation, and execution of a mass tunnel escape. The narrative weaves daily routines and the camp's oppressive atmosphere with technical descriptions of the shaft, tools, and concealment, and sketches of the men who took part and their accomplices. It records immediate reprisals and partial recaptures, follows the subsequent attempts to reach safety, and outlines the practical measures that enabled some to make good their escape, all illustrated and supported by plans and firsthand testimony.
