Wednesday, September 13, 1939 www.onwar.com
From Berlin... The German Armed Forces High Command (OKW) announces that civilian targets in Poland are being bombed because civilians are involving themselves in the fighting.

In Poland... A small German infantry force begins to cross the Vistula just south of Warsaw. The Bzura battles are now going badly for the Polish forces. The heaviest fighting will be over by September 15th but some engagements will continue until the 19th. Although the Germans will take their largest single haul of 150,000 prisoners in this battle, by September 19th, units of two Polish brigades and elements of others will manage to escape to Warsaw.

From Warsaw... The US ambassador to Poland, Anthony J. Drexel Biddle, Jr., reports that German bombers are attacking the civilian population. He says "they are releasing bombs they carry even when they are in no doubt as to the identity of their objectives.

In Paris... The French Prime Minister, Edouard Daladier, forms a War Cabinet in which he is responsible for foreign affairs as well as retaining the portfolios of war and national defense. The former foreign minister, Georges Bonnet, is appointed Minister of Justice. Raoul Dautry is appointed Minister of Armaments and Georges Pernot is appointed Minister of Blockade, both are new portfolios related to the war effort. Daladier is keen to have a war cabinet that will enable France to put recent divisions aside and fight the war with a spirit of national unity.

In Algeria... The French cruiser La Tour d'Auvergne sinks from an accidental explosion at Casablanca.
