Phoney War

The Phoney War was a name for the eight months during World War II from Poland being invaded in September 1939 to France being invaded in May 1940.
During that time, there were no major military operations in Europe. The United Kingdom and French declared war and a blockade against Nazi Germany, which did likewise by declaring war and blockade. The Battle of the Atlantic had begun in which German submarines destroyed many British ships. The British Royal Air Force dropped propaganda leaflets on Germany, and Canadian troops began to arrive in Britain.
In April 1940, Germany invaded Denmark and Norway. Both the Allies and the Axis began to fight each other strongly again. Britain and France needed many weapons quickly and so they began to buy them from American weapon companies. The Americans remained neutral but helped Britain and France by selling weapons cheaply and then by the Lend-Lease program of military equipment and supplies.
