The Führer has ordered that the enemy employs in partisan warfare Communist-trained fanatics who do not hesitate to commit any atrocity. It is more than ever a question of life and death. This fight has nothing to do with soldierly gallantry or principles of the Geneva Convention. If the fight against the partisans in the East, as well as in the Balkans, is not waged with the most brutal means, we will shortly reach the point where the available forces are insufficient to control the area. It is therefore not only justified, but it is the duty of the troops to use all means without restriction, even against women and children, so long as it ensures success. Any consideration for the partisans is a crime against the German people.
