World War II Axis Military History Day-by-Day: September

September 1

September 1, 1939: Three German Armeegruppen begin the invasion of Poland at 4:45am CET, offically launching the world into what would be the most destructive and deadly war in all of history. Massive strikes by the Luftwaffe destroy vital communications and assembly areas, decimating the Polish air force on the ground. Panzer and motorized divisions make deep penetrations into the Polish defenses, using tactics soon to be known as the Blitzkrieg. Offically, the first shots of the war are fired from the 280mm deck guns of the vintage First World War Battleship Schleswig-Holstein. The ship had survived the ravages of WWI and entered service in the Kriegsmarine in 1935, serving initially as a cadet training ship. Under the guise of honoring the anniversary of the Battle of Tannenburg, the German Battleship, complete with a hidden cargo of Marine Assualt troops, was allowed by the Poles to anchor directly off the strategic island of Westerplatte, located at the mouth of the Vistula River in Danzig. At 4:47am, permission was given to the ship to open fire on the island, a strategic point on the Baltic Coast needed to support the troops advancing to the south. Shortly after 4:47am, the ship opened up its massive main guns, firing at near-pointblank range and zero elevation. Needless-to-say, the shells literally pounded the small island, but although the ships guns devestated the target, they inflicted minimal casualties on the Poles stationed within. When the Marinesturmkompanie hidden within the Battleship disembarked and launched its main assault on the island, it was repulsed after taking heavy casualties. Another assault was launched later in the morning, again by the Marinesturmkompanie, after more shelling from the Schleswig-Holstein, but this assault also ending in heavy German casualties. The Westerplatte would prove impossible to take on the first day of WWII.
