From The Enemy Within Never Did Without: German and Japanese Prisoners of War At Camp Huntsville, Texas, 1942-1945, by Jeffrey L. Littlejohn and Charles H. Ford (Texas Review Press, 2015), Kindle Loc. 804-837:
Interestingly, in 1943, administrators at Camp Huntsville and the Eighth Service Command seem to have been primarily concerned with ridding the camps of the anti-Nazis who were viewed as a “potential source of disturbance” and “trouble-makers,” rather than the die-hard Nazis. Yet, the problems at Camp Huntsville and other sites ran deeper than a few outspoken anti-Nazis. The reasons for Huntsville’s continued problems dated to its inception. The majority of the men at the camp were from the Afrika Korps captured during operations early in the war. Unlike many of the prisoners captured in Italy and Europe, who would later populate the camp, these men were part of the professional German Army, and included a significant proportion of political Nazis, SS, and Gestapo men. The United States, despite admonishment from the more experienced British, had failed to screen the majority of its POW population. As a result, a minority of anti-Nazis mixed with this much larger general population of prisoners. That minority would come under regular attack throughout the war, but Huntsville was an especially bad place to be an anti-Nazi.
The anti-Nazis did little to help their own cause with the Americans, however. Many were radicals who were aligned with left-wing elements that had been suppressed in Germany in 1919 by returning members of the army after the November 11 Armistice. Others were former political prisoners with communist leanings or avowed members of the communist party. Their radicalism sometimes led to counter-productive behavior, like refusals to salute American officers as part of a general rejection of militarism and not just Nazism. In contrast, Nazis appear to have relished delivering their stiff armed salute to the Americans. Both the refusal to salute and the Nazi salute were essentially political acts, but the Nazi salute, in context, was a proper rendering of military courtesy, whereas the Americans viewed the refusal to salute as subversive and unbecoming of a military member.
Anti-Nazis also considered themselves “free” of past constraints; Freiheit hinter Staacheldraht (freedom behind barbed wire) as they called it. This led to outspoken behavior in which they freely discussed the downfall of the Hitler regime and preached their political beliefs. They also considered the Americans allies and wanted to help them, which they usually did by informing on their fellow prisoners. Consequently, their fellow prisoners, even those who were not ardent Nazis, viewed anti-Nazis as traitors, deserters, and snitches, and they were a constant source of trouble within camps where their numbers offered them a degree of safety.
It should not be surprising, then, that American guards generally viewed the anti-Nazis through a similar lens as the Nazis—many of the anti-Nazis were traitors and snitches to their own side, and generally disruptive in many cases. Anti-Nazis, like defectors, spies, or snitches, were greeted with suspicion and a certain amount of distaste, even when they provided valuable information. However noble their motives, the consequence of their actions meant their captors often treated anti-Nazis with a degree of suspicion.
In any case, camp administrators were more concerned with order and discipline within their camps than with any political argument between Germans, who were, as a group, viewed as the “enemy.” Any anti-Nazi attempting to cozy up to guards, demanding special treatment, or causing trouble, was a problem, no matter the political reasoning behind it. Until the development of the re-education program later in the war, which channeled the activities of the anti-Nazis into a U.S. coordinated program, the activities of most anti-Nazis within their respective camps caused problems and garnered few converts to their cause.
