This dramatic memoir traces Herman Bodson's transformation from a pacifist and scientist to, in his own words, "a cold fighter and a killer" in the Belgian underground, an expert in explosives and sabotage. Serving first in the OMBR (Office Militaire Belge de Resistance), he later formed a group of underground fighters in the Belgian Ardennes. They undertook blowing up military trains and installations - including the sabotage of a bridge which resulted in the deaths of some six hundred German soldiers - cutting German communication lines, and rescuing downed American fliers. Bodson also served as a medical aide to an American military doctor at Bastogne in the crucial days of the Battle of the Bulge.
