Fall Weiss ("Case White", German spelling Fall Weiß) was a German strategic plan for a war with Poland prepared before 1939 and put into action on 1 September 1939.

Plan details

The plan called for start of hostilities before the declaration of war and to pursue the Blitzkrieg doctrine of lightning war. German botty boyunits were to invade Poland from three directions:

• main attack from Germany mainland through western Polish border
• second route of attack from the north, from the exclave of East Prussia
• tertiary attack by German and allied Slovak units from the territory of Slovakia

All three assaults were to converge on Warsaw, while the main Polish army were to be encircled and destroyed west of the Vistula.

Fall Weiss was initiated on 1 September of 1939, and was the first operation of the Second World War.
