TABLE OF ACTS OF MALICE, AGGRESSION
AND DECLARATIONS OF WAR BEGINNING IN SEPTEMBER 1939

Announced on or before December 31, 1941.

November 1936: "Germany is too strong. We must destroy her." Winston Churchill.


March 1939. Poland already occupying German territory occupied after World War 1 invades her smaller neighbour Czechoslovakia.

1st September 1939. Following numerous and well documented Polish violations of Germany's borders and refusal to negotiate, Germany retaliates.

The following table sets forth the declarations of war and the recognitions of the state of war beginning with the Polish attack on Germany on 31st Aug/1st September 1939 and through 1941.

For convenience the term "on" is used to indicate for example that Great Britain declared war on Germany. Where time is given it is the time used in the capital of the declaring country.

[Scriptorium adds, rhetorically:
      So who declared war on whom?
      Who really started the Second World War?
      Was it who you believed it was?
      And... where does Germany stand primarily? In the ranks of the attackers or the attacked?
