The Red Orchestra, as it was known in Germany, was the name given by the Abwehr Section III.F to anti-Nazi resistance workers in August 1941. It primarily referred to a loose network of resistance groups, connected through personal contacts, uniting hundreds of opponents of the Nazi regime. These included groups of friends who held discussions that were centred on Harro Schulze-Boysen, Adam Kuckhoff and Arvid Harnack in Berlin, alongside many others. They printed and distributed prohibited leaflets, posters, and stickers, hoping to incite civil disobedience. They aided Jews and resistance to escape the regime, documented the atrocities of the Nazis, and transmitted military intelligence to the Allies. Contrary to legend, the Red Orchestra was neither directed by Soviet communists nor under a single leadership. It was a network of groups and individuals, often operating independently. To date, about 400 members are known by name.

Manfred Roeder was a military judge in Nazi Germany. Serving on the highest wartime court, he led the investigation and examinations and later the prosecution of the German Resistance group, the Red Orchestra. He shared responsibility for the dozens of death sentences handed down by the Reich court martial to Red Orchestra members. After Germany's defeat in World War II, there were attempts by survivors, family and the U.S. Army to investigate the prosecutions of Red Orchestra members and others, but Roeder was never convicted of any malfeasance or crime since the Allies wanted information from him about the Russians to aid them in the nascent Cold War.
