This study examines the relationship between British and American officials and the fifty-five Wehrmacht general officers who were held as prisoners of war in the United States during World War II. This relationship transformed as the war developed and new national security concerns emerged in the immediate postwar era. As largely evidenced by the records of the United States War Department and the British War Office, the transformation of this relationship illustrates two important points. First, despite some similarities, the respective priorities of British and American authorities regarding their POW general officers differed significantly. British officials consistently interrogated and eavesdropped on all of their senior officer prisoners, primarily seeking operational and tactical intelligence to aid the Allied war effort. By contrast, American officials initially had little regard for the value of Wehrmacht general officer POWs. Second, by the end of the war, admiration for the prowess of German officers and the German military tradition in particular, coupled with anxiety about Soviet intentions and the strength of the Red Army, drove Washington into a collaborative relationship with many of the Wehrmacht general officers in its custody. The evolution of America's national security concerns in the years immediately following the end of World War II impacted its policy governing the treatment of high-ranking prisoners of war.
