Westerplatte, Gdańsk
At 4:45 on Friday 1 September 1939 the German training battleship Schleswig-Holstein, moored in the Gdańsk harbour channel, opens fire on the Polish Military Transit Depot at Westerplatte, the first shots of the Second World War in Europe.

The moment
The battleship came on a courtesy visit
The Schleswig-Holstein, an old German training battleship, left Kiel on 18 August 1939 and entered Gdańsk on 25 August on what was billed as a courtesy visit. It moored in the harbour channel about 150 metres from Westerplatte. It was meant to be in place for an attack on 26 August; when the invasion was put off, the ship waited six more days.
At four in the morning on Friday 1 September it moved to the channel bend known as the Five Whistles, for a better field of fire. A Kriegsmarine assault company of 229 men had landed in the night near the old Wisłoujście fortress.
At 4:45 the forward turret opened fire; the ship's log gives 4:48. Shells weighing 330 kilograms blew in the depot's railway gate and stretches of its brick wall. These were the first shots of the Second World War in Europe.
A depot meant for 88 soldiers
Westerplatte, a wooded spit at the mouth of the port, lay in the Free City of Danzig. In 1924 the League of Nations agreed to hand it to Poland, and in 1925 the city leased it to Poland free of charge as a Military Transit Depot. The League's Council limited its garrison to 88 men.
By September 1939 the depot held 182 soldiers, including five officers and a doctor, under Major Henryk Sucharski; some sources give over 200. They had five reinforced concrete guardhouses, modern barracks and field positions dug that August. The plan assumed they would hold for twelve hours.
Seven days and thirteen assaults
The first German assault was beaten back after about ninety minutes. On the evening of 2 September nearly sixty Stuka dive bombers attacked, and at least six defenders died when Guardhouse No. 5 was hit.
At 10:15 on 7 September Sucharski ordered the surrender, citing the losses, the exhaustion of his men, the condition of the wounded and an enemy almost twenty times stronger. The defenders had repelled thirteen assaults. Between fifteen and twenty of them had been killed and some fifty wounded. German losses, once put at 300 dead, are now estimated at 30 to 50.
What happened inside the depot is still argued over. Some accounts say Sucharski broke down after the air raid and that his deputy, Captain Franciszek Dąbrowski, quietly took over; a disputed thesis speaks of a mutiny among officers.
Why Poland marks 4:45
Westerplatte is the Polish symbol of the start of the Second World War, and the anniversary is marked there every 1 September at 4:45. The 25-metre Monument to the Coast Defenders, unveiled in 1966, carries the words "Never again war".
It is not exactly the ground of 1939. When the harbour channel was widened in 1967, Guardhouse No. 1 was moved on rails in one piece. Remembrance here has been politically contested too: in 2020 the state took over the city-owned land around the monument, a step the Supreme Administrative Court ruled unlawful in 2021. In November 2022 ten of the defenders were buried in a new military cemetery on the peninsula.
