Chronology of World War II
Luftwaffe bombing Warsaw
Monday, September 25, 1939 www.onwar.com
In Poland... The Germans issue a second ultimatum to the Polish Warsaw garrison. Meanwhile, German forces step up their bombardment of Warsaw and add heavy air attacks to it. Some 400 Luftwaffe bombers and Stuka dive bombers make repeated sorties, starting significant fires. Hitler wishes to complete the conquest as soon as possible and since the garrison is fairly strong, it is necessary to force them to submit by terrorizing the civilian population. The bombing continues until the surrender.

In Germany... Bread and flour rationing is introduced. The distribution of food ration cards is completed.

In Berlin... Hitler issues his fourth war directive, ordering increased attacks on Allied shipping a swift conclusion to the war in Poland.

In the North Atlantic... After a near miss in an air attack, German propaganda claims that the British aircraft carrier Ark Royal has been sunk. This is the first of several such false claims during the coming months. The attack also marks the debut of the German Ju88 bomber.
