March 1936
Robert Vansittart, the Permanent Undersecretary of State for Foreign Affairs in Great Britain, writes a memorandum warning that Germany's rearmament program would serve Adolf Hitler's plan to annex Austria, the Sudetenland, the Baltic states, and the Polish Corridor to East Prussia.

The Joint Planning Committee of the Chiefs of Staff in England declares: "We are convinced that Germany would plan to gain her victory rapidly. Her first attacks would be designed as knock-out blows" referring to London being heavily bombed over a few weeks."
