Friday 1 September 1939

Old German battleship SMS Schleswig-Holstein opens fire on the morning of 1 September 1939.

Preliminary Fact: The previous night, the Germans had implemented "Operation Himmler." This involved the staging of "provocations" along the German/Polish border, most famously at the radio station at Gleiwitz. Hitler has used this operation to build a propaganda "justification" for an invasion of Poland.

Germany, Air Operations: Case White, the invasion of Poland, begins. At 4:40 a.m., the Luftwaffe attacks the Polish town of Wieluń, causing extensive damage and killing an estimated 1200 civilians and soldiers. Later, air attacks commence against Kraków, Łódź, and Warsaw.

Operation Wasserkante, the air attack on Warsaw, is composed of four bomber groups but is hampered by poor weather. In addition, PZL P.11 fighters of the Pursuit Brigade shot down 16 German aircraft for the loss of 10 of their own. While a major Polish success, the Germans can sustain their losses, the Poles cannot.
Germany, Naval Operations:  SMS Schleswig-Holstein, a pre-dreadnought laid down in 1905 which had participated in the Battle of Jutland, opens fire at about 4:45 a.m. The target is a Polish ammunition depot at Westerplatte by the Port of Danzig. Many consider this the first "official" shot of the war, though an entire war machine was on the move at the time and indications are that other forces were in play before this action. Choosing this as the start was more due to the convenience of cameras being present that recorded the action than reality. The salvo initiates a ground attack on the depot that is initially unsuccessful.

In London, September 1st, 1939. Three  Kennedys - Joe Junior, Kathleen, and Jack - hurry to attend a special sitting of the British House of Commons. Their father, Joe, is the Ambassador to the Court of St. James.

Germany, Army Operations: Shortly before 5 a.m., German forces move across the frontier. The main attack, though, does not begin until 8 a.m., when the Wehrmacht attacks Mokra. Three pincers aim at Warsaw from East Prussia in the north, Slovakia (a German ally) in the south, and straight east from Germany proper.

The primary forces (53 Divisions) entering Poland under Army (Heer) Commander-in-Chief Walther von Brauchitsch:

• Heeresgruppe Nord (Army Group North) (Fedor von Bock);
• Heeresgrupped Sud (Army Group South) (Karl Rudolf von Rundstedt);

The individual armies are:

• 3rd Army (Georg von Küchler)
• 4th Army (Günther von Kluge)
• 8th Army (Johannes Blaskowitz)
• 10th Army (Walter von Reichenau)
• 14th Army (Wilhelm von List).

There are two Luftwaffe forces corresponding to the Army Groups and giving them dedicated support (one for each):

• Loftflotte 1 (Albert Kesselring);
• Luftflotte 4 (Alexander Löhr);

Poland, Army Operations: Polish forces successfully defend against an opening attack on the strategic Dirschau Bridge designed to capture it intact. Elsewhere, though, resistance is light.

Germany, Diplomacy: Chancellor Adolf Hitler announces the invasion to the Reichstag at the Kroll Opera House (the Reichstag building having been burned in the 27 February 1933 Reichstag Fire). Hitler states that the hostilities are a defensive action. He further states, "If anything should befall me in this struggle, then my successor shall be party-member Goering." He does not ask for a declaration of war, but nobody is left in any doubt that war has commenced.

Hitler holds out hope, encouraged by German Foreign Minister Ribbentrop, that Britain and France will not intervene. Unofficial/amateur Swedish diplomat Birger Dahlerus, at the behest of Hermann Goering, phones the permanent undersecretary of the British Foreign Office in London, Sir Alexander Cadogan early in the morning. He wants to broker some kind of understanding. Cadogan tells him that no talks are possible unless and until Germany withdraws from Poland. Around noon, Dahlerus goes to the British embassy in Berlin with the same proposal and is told the same thing.

Germany, Home Front: In sharp contrast to August 1914, when there were wild celebrations upon the outbreak of World War I in Germany and Austria-Hungary, there are few if any public demonstrations in Germany. Crews are busy securing various art treasures and buildings against air attack.

Adolf Hitler addresses the Reichstag on 1 September 1939.

Future History: Lily Tomlin is born on 1 September 1939. She gains fame in the 1960s and thereafter as a television/film/stage comedienne.
