"The Führer felt obliged to strike back only after Polish troops had crossed the German border at several places. The German fight is a defensive fight. We fight because we were forced to fight by the insults and demands against us, because of the brutal suppression of ethnic Germans in Poland, and because of the open announcements that they would do everything in their power to strangle National Socialist Germany through military or economic means." -- Die Wehrmacht (1939, Nr. 19, p. 2, available online)
