Adolf Hitler's Proclamation to the German Army (1 September 1939)
The Polish State has refused the peaceful settlement of relations which I desired, and has appealed to arms. Germans in Poland are persecuted with bloody terror and driven from their houses. A series of violations of the frontier, intolerable to a great Power, prove that Poland is no longer willing to respect the frontier of the Reich.
In order to put an end to this lunacy, I have no other choice than to meet force with force from now on. The German Army will fight the battle for the honour and the vital rights of reborn Germany with hard determination. I expect that every soldier, mindful of the great traditions of eternal German soldiery, will ever remain conscious that he is a representative of the National-Socialist Greater Germany. Long live our people and our Reich!
