That time Germany scuttled its own navy in sneaky scheme
In June 1919, the bulk of the German High Seas Fleet was sitting at anchor at Scapa Flow in the Orkney Islands. The cruiser Emden sent out the message, "Paragraph 11; confirm." Then, all 74 of the warships in the natural harbor attempted to scuttle themselves en masse, and 52 successfully destroyed themselves before British sailors were able to beach them or stop their sinking. It's important to remember for this story that wars have two ending points. There's the armistice that stops the actual fighting, and then a lengthy peace process will usually result in a full treaty ending the war. After the armistice ended World War I fighting on Nov. 11, 1918, a large portion of the German navy was interned for the treaty process.
The navy had been largely sidelined during the war thanks to a British blockade, so it was largely intact that November. And the Allied powers, in order to ensure that Germany went through with the peace process, demanded that the nation's most powerful and modern fleet be sequestered at a neutral port.
But, no nearby neutral port agreed to accept the ships, and so 70 of Germany's best vessels were sent to the British harbor at Scapa Flow, a natural harbor that housed one of the British fleets. Four other German ships would later meet them there.
When the German ships were officially handed over on November 21, literally hundreds of ships and thousands of people were present to watch the event. Over 190 Allied ships escorted the first batch of 70 ships from Germany to surrender, making that day the largest concentration of naval power in the history of mankind, even if 70 of the ships had breech blocks in their guns to prevent a sudden return to hostilities.
But the fleet languished there for months. Morale on the German ships was bad during the war and worse while they were confined to ships on short rations in British territory. And the German commander had an order from his superiors to prevent the seizure of the ships by any means necessary.
The German navy seems to have believed that the ships would eventually be returned, Britain wanted to see them scrapped, and the rest of the Allies wanted to divvy them up. But as the negotiations in France made it clear that Germany would not get the ships back, German Adm. Ludwig von Reuter planned for how to destroy his own fleet.
He knew that the deadline for Germany to sign the treaty or face a resumption of hostilities was June 21, 1919. So, at 10:30 a.m., after he saw the bulk of the British fleet at Scapa Flow depart for maneuvers, he sent out the innocuous-sounding signal to scuttle the fleet, "Paragraph 11; confirm."
He didn't know that the deadline had been extended to June 23, but this actually worked out well for him. The British commander had plans to seize the German ships on June 23 if the German diplomats still hadn't signed the treaty by then.
And so the ships suddenly began to sink. The German sailors raised their German navy flags from their masts for the first time since they had arrived in the harbor. British sailors in the harbor quickly alerted their own fleet as to what was happening, and the fleet rushed back to save what it could.
The sight they met when they re-entered the harbor was surreal. As Sub-Lieutenant Edward Hugh Markham David said when he wrote to his mother of the events:
A good half of the German fleet had already disappeared, the water was one mass of wreckage of every description, boats, carley floats, chairs, tables and human beings, and the 'Bayern' the largest German battleship, her bow reared vertically out of the water was in the act of crashing finally bottomwards, which she did a few seconds later, in a cloud of smoke bursting her boilers as she went.
The German admiral proceeded to the British flagship and declared that he had "come to surrender my men and myself. I have nudding else."
British sailors were quickly dispatched to the sinking ships to re-close the valves and pump water out. Some British sailors nearly drowned in this endeavor, but they saved 22 of the ships as 52 settled into the mud at the bottom.
The British sailors were under orders to only kill those Germans who refused to close valves when ordered or who resisted British actions to save the vessels. Nine German sailors were killed, but there is some controversy over whether all these sailors had resisted or not.
Still, it was the single largest loss of naval power in one day in human history, even though it was a calm day and no battle had actually taken place.
Salvage operators bought some of the ships in the later decades. One man, Ernest Cox, successfully ran the salvage of 30 ships before calling it quits. But many of the vessels sunk that day still remain on the harbor floor where they are now popular spots for divers.
