During World War II, a number of Frenchmen volunteered for service in the Wehrmacht. For the purposes of this question, these men came from two sources: 1) genuine volunteers (freiwillige or "free willed individuals), and 2) former prisoners of war, who saw service in the Wehrmacht as a "lesser evil" than captivity.
Of the Frenchmen who served in the Wehrmacht,* how many were former POWs who only "volunteered" to escape captivity? The reason for the question is that the Germans were quite successful in getting former Soviet POWs (Hiwis)to enlist. How successful were they with Frenchmen who were under similar duress?
