U-boats were still in their infancy in 1914, and most naval officers looked down on the fleet. At best, they were considered defensive weapons that could help hold an enemy fleet away from the coasts in naval warfare. But then, on Sept. 22, 1914, a German U-boat saw a cluster of three British warships and managed to sink them all in under 90 minutes without suffering damage.
The September engagement took place while the war was less than two months old. The three British cruisers were old and considered unreliable. They were so fragile, in fact, that many naval leaders had argued they shouldn’t be assigned to the North Sea at all, but they were overruled. The three vessels and their escorts became known as the “Livebait Squadron.”
Despite the ships’ flaws, though, the crews did know how to mitigate their risk of submarine attack, mostly through zigzagging and posting lookouts to watch for periscopes or surfaced vessels, but they didn’t take those precautions.
The seas were rough, too rough for their destroyer escort, and so the British officers assumed they were too rough for submarines. This wasn’t entirely off base. Submarines rode close to the surface or even above it most of the time, and the water tossed around the boats quite easily. America’s future Fleet Adm. Chester Nimitz, who spent a lot of time on submarines early in his career, would complain about how badly the boats were battered by the waves.
But for the crew members of the German boat U-9, it was just a cross they had to bear. It wasn’t like they could slip back to Germany every time the waves got bad. So, on September 22, they were still in their assigned zone, riding close to the surface and sucking up any pain, when the Livebait Squadron came into view.
And when they spotted the three British cruisers, none of them zigzagging to make their shot harder, they decided to go ahead and rob the Royal Navy of one of those big, important ships. The captain, Kapitänleutnan Otto Weddigen, ordered two torpedoes fired at the lead vessel, the HMS Aboukir.
One of them struck home, setting off a massive explosion that unquestionably doomed the ship. But no one had spotted the tell-tale stream of bubbles from the torpedo as it had raced to the ship in the rough seas, and so the ship’s captain just assumed he had hit a mine. He signaled to the other ships for assistance.
On the German U-boat, it must have looked like a gift from heaven. If the cruisers had realized they were under attack and set up to sink the U-boat, then the U-9 would have had to choose between bailing on the fight, diving for a few minutes or hours, and risk sinking in the engagement. But since the cruisers just lowered their lifeboats and didn’t prepare for combat, the U-9 could take another consequence-free swing at Livebait.
Weddigen fired next at the HMS Hogue, dooming that ship as well. By this point, the remaining ship, HMS Cressy understood it was under attack and deployed torpedo defense batteries and began to sail in a zigzag pattern, but it stayed in the area to try and rescue more sailors. This was a mistake.
At 7:20 and then 7:30, Weddigen fired torpedoes that sank it, and then watched it drop beneath the waves. Low on ammo and already successful beyond his wildest dreams, Weddigen turned for home.
On the surface, Dutch and English ships raced to save all the sailors they could, including 15-year-old Kit Wykeham-Musgrave of the HMS Aboukir. He had barely survived the suction of the first ship sinking, had been rescued by the crew of the Hogue and made it onboard right before that ship was sank, and then climbed onto the Cressy only to have it shot out from under him as well.
Almost 1,400 enlisted men and 62 officers would not be so lucky, drowning in the rough and cold water of the North Sea instead.
The German sailors were greeted as heroes in their home port. The entire crew received Iron Crosses Second Class, and the captain was awarded that medal as well as the Iron Cross First Class. But in Britain, the people were furious and demanded that senior Navy leadership be held accountable.
For Weddigen, the success would be sweet. He received his medals from the Kaiser personally and wrote a memoir titled The First Submarine Blow is Struck. (His success on September 22, while revolutionary, was not actually the first “submarine blow” as both the German and British navies had already each lost a cruiser to the other side’s submarines.)
But he would not long enjoy his fame. While the U-9 would rack up 18 kills before retiring in 1916, Weddigen was soon re-assigned to U-boat 29. While attacking British ships in March 1915, the boat was spotted by the famous British battleship HMS Dreadnought which proceeded to ram and sink the German submarine, killing Weddigen.
(A final admin note: Weddigen claims in his memoirs to have fired only four torpedoes that day: one at the Aboukir, one at the Hogue, and two at the Cressy, all of which hit. This might have been true, but his memoirs reek of propaganda and were written in the late months of 1914 when his fame was peaking. Naval warfare historians think it is more likely that he fired six and had four hits.)
