Thus, the Luftwaffe=s contribution to victory could involve attacks on an enemy's air forces, his army, his fleet, or even the destruction of his resources and armament industry. The conditions of the general situation and overall national strategy would determine in what form one would wage the air battle (Murray 7-8).

The Second World War actually began with Germany's invasion of Poland in 1939, and Hitler used a staged incident as his excuse. The war started with an attack by the Luftwaffe on bridges over the Vistula River at Dirschau (Jablonski 21). Richtofen claimed that the methods he had used in Spain would be effective elsewhere, and while there were some in the high command who doubted this, he was allowed to create a special air division that would embody his ideas of tactical air power. His task in Poland was to punch holes in the Polish fortifications along the border so the army could enter, and a variety of planes made the attacks on airfields inside Poland. Other planes of the Luftwaffe were flying up and down the length of Poland to destroy the life lines of the Polish ground armies, pulverizing the roads and railways in the region. In some cases, incendiary bombs known as flambos were dropped on Polish troops (The Luftwaffe 20-24).
