The Commando Order (Kommandobefehl) was issued by the OKW, the high command of the German armed forces, on 18 October 1942. This order stated that all Allied commandos captured in Europe and Africa should be summarily executed without trial, even if in proper uniforms or if they attempted to surrender. Any commando or small group of commandos or a similar unit, agents, and saboteurs not in proper uniforms who fell into the hands of the German forces by some means other than direct combat (by being apprehended by the police in occupied territories, for instance), were to be handed over immediately to the Sicherheitsdienst (SD, or Security Service) for immediate execution.
According to the OKW, this was to be done in retaliation for their opponents "employing in their conduct of the war, methods which contravene the International Convention of Geneva". The German high command alleged that they had ascertained from "captured orders" that Allied commandos were "instructed not only to tie up prisoners, but also to kill out-of-hand unarmed captives who they think might prove an encumbrance to them, or hinder them in successfully carrying out their aims", and that commandos had been ordered to kill prisoners.
This order, which was issued in secret, made it clear that failure to carry out its directives by any commander or officer would be considered an act of negligence punishable under German military law. This was in fact the second "Commando Order", the first being issued by Generalfeldmarschall Gerd von Rundstedt on 21 July 1942, stipulating that parachutists should be handed over to the Gestapo. Shortly after World War II, at the Nuremberg Trials, the Commando Order was found to be a direct breach of the laws of war, and German officers who carried out illegal executions under the Commando Order were found guilty of war crimes and sentenced to death, or, in two cases, extended incarceration.
The Commando Order mentioned violations of the Geneva Conventions by Allied commandos and cites these violations as justification for its directives.
