Führer Directive 21 .
Translation of Directive #21 as written by Adolf Hitler, ordering German forces to prepare an attack on Soviet Russia in 1941, designated Operation Barbarossa. The orders also outline the overall operational goals and considerations in the coming operation for each branch of the armed forces of Germany, as well as those of their allies (primarily Finland and Romania). Launched by Hitler's order on June 22, 1941, Operation Barbarossa became the single largest land battle in history, and the stalemate and eventual defeat that resulted for Germany signalled the beginning of the end for the Third Reich.

Operation Barbarossa (Unternehmen Barbarossa) was the code name for the Axis invasion of the Soviet Union, which started on Sunday, 22 June 1941, during WW2. The operation put into action Nazi Germany's ideological goal of conquering the western Soviet Union so as to repopulate it with Germans. The German Generalplan Ost aimed to use some of the conquered as slave labour for the Axis war effort, to acquire the oil reserves of the Caucasus and the agricultural resources of Soviet territories, and eventually to annihilate the Slavic peoples and create Lebensraum for Germany.

Pre-Barbarossa invasion:

During WW2, the Barbarossa decree was one of the Wehrmacht criminal orders given on 13 May 1941, shortly before Operation Barbarossa, the invasion of the Soviet Union. The decree was laid out by Adolf Hitler during a high level meeting with military officials on March 30, 1941, where he declared that war against Soviet Russia would be a war of extermination, in which both the political and intellectual elites of Russia would be eradicated by German forces, in order to ensure a long-lasting German victory. Hitler underlined that executions would not be a matter for military courts, but for the organised action of the military. The decree, issued by Field Marshal Keitel a few weeks before Operation Barbarossa, exempted punishable offenses committed by enemy civilians (in Russia) from the jurisdiction of military justice. Suspects were to be brought before an officer who would decide if they were to be shot. Prosecution of offenses against civilians by members of the Wehrmacht was decreed to be "not required" unless necessary for the maintenance of discipline.
