Friends of Padre Steve’s World,
In September 1914 most naval experts held the submarine was not much of a threat. The submarines of the day were limited in range, diving depth, speed, armament and endurance. The U-9 was powered by kerosine engines on the surface which charged batteries which were used when the boats were submerged. Later submarines would be powered by diesel engines.
U-9 was small, displacing only 543 tons on surface and 674 submerged. She was just 188 feet long and had a beam of just 19.7 feet. As such, the living conditions for her crew of 4 officers and 25 enlisted men were less than spartan. She was armed with four 20 inch torpedo tubes, two forward and two aft and carried six torpedoes, four in the tubes and two reloads for the forward torpedo tubes.
The boat was commissioned in April 1910 and on the outbreak of the First World War she was commanded by Kapitänleutnant Otto Weddigen. On September 22nd 1914 with enormous battles raging on the Western Front and the High Seas Fleet in port the soon to be famous submarine was patrolling in the North Sea. The U-9 was about 18 miles off the Dutch Coast near the Hook of Holland when she encountered three ships of the Royal Navy’s 7th Cruiser Squadron.
The squadron was composed of four obsolete Cressy Class Armored Cruisers, the HMS Cressy, HMS, Aboukir, HMS Hogue, and HMS Euryalus. each displacing 12,000 tons and mounting two 9.2” and 12 6” guns. Manned primarily by recently called up reservists the ships were derisively known as the “Live Bait Squadron” and on that September morning they would unfortunately live up to that title. However, Euryalus had been detached from the squadron on September 20th to return to Harwich to coal. The squadron commander, Rear Admiral Christian aboard Euryalus was prevented from transferring his flag due to high seas and command passed to Captain John Drummond of Aboukir. Adding to the approaching tragedy was the fact that First Lord of the Admiralty Winston Churchill had sent a commander to the First Sea Lord, Sir Louis Battenberg that the ships should be removed from that duty because of “the risks to such ships is not justified by the services they render.” Battenberg initially agreed but was persuaded by his Chief of Staff, Admiral Charles Sturdee to keep them on station because they were better than nothing. Churchill assumed that his order had been obeyed and never followed up and the rest was history.
The ships were steaming in a line ahead formation when Weddigen on the U-9 spotted them about 0600. They were not zig-zagging to lessen the chance of submarine attack and thought they had posted lookouts had no idea that U-9 was stalking them.
Weddigen on worked the boat into what he felt was a better firing position and launched his first torpedo at the center cruiser, the Aboukir at 0620 from a distance of just 550 yards. The torpedo struck her midships and broke her back. She began to sink and within 25 minutes capsize taking 527 of her crew of 760 down with her. Weddigen described the scene:
“There was a fountain of water, a burst of smoke, a flash of fire, and part of the cruiser rose in the air. Then I heard a roar and felt reverberations sent through the water by the detonation.”
Thinking that Aboukir had struck a mine the Cressy and Hogue moved in to rescue survivors. Weddigen had surfaced to observe the British and then fired two torpedoes into Hogue from a range of just 300 yards and then dived as Hogue opened fire. The torpedoes struck the ancient armored cruiser causing massive damage, which was compounded by the fact that her watertight doors were still open. Thus, within 15 minutes of being hit Hogue capsized and sank.

The British now knew that a submarine was responsible for the attack and the last ship and after reloading his forward tubes attacked Cressy at 0720 firing two torpedoes from her stern tubes. Weddigen then surfaced in order to bring his bow tubes, now reloaded, into action and fired another shot. As he did so the British cruiser opened fire and attempted to ram the surfaced U-9. But Cressy was unable to avoid the fate of her sisters, struck by two torpedoes she capsized and then sank at 0755.
In little more than an hour and a half U-9 had sunk three cruisers with a loss of 1459 British sailors. Only 837 crew members from all three ships survived.

Weddigen then moved off as he knew that the British would be looking for the U-9. When the boat returned to port Weddigen and his crew were hailed as heroes. Weddigen was awarded the Iron Cross First Class and the boat was one of only two ships of the Imperial Navy awarded the Iron Cross, the other being the Light Cruiser Emden.
The plucky U-9 would survive the war, sinking another cruiser, the HMS Hawke on October 15th 1914, less than a month after sinking Aboukir, Hogue, and Cressy. She would also sink 13 other merchant ships or fishing boats for a total of over 50,000 tons. She was withdrawn from front line service in 1916 and assigned to training duties. Weddigen was killed on March 18th 1915 when his new command the U-29 was sunk.
The U-9 Returns to Wilhelmshaven on September 24th 1914
Future First Sea Lord Dudley Pound then serving on the Battleship St. Vincent wrote: “Much as one regrets the loss of life one cannot help thinking that it is a useful warning to us — we had almost begun to consider the German submarines as no good and our awakening which had to come sooner or later and it might have been accompanied by the loss of some of our Battle Fleet”.
Submarines would go on to be one of the most feared and effective weapons developed for naval warfare. German U-Boats nearly brought Britain to its knees in both World Wars and the submarines of the US Navy’s Pacific Fleet decimated the Japanese merchant fleet and inflicted great losses on the Imperial Japanese Navy. While the US Navy replaced its losses in early 1942 it was the submarine force that according to Admiral Chester Nimitz “held the lines against the enemy.”
Today the most deadly submarines ever built prowl underneath the surface of the world’s oceans. Nuclear powered and advanced diesel electric boats armed with torpedoes and cruise missiles, and giant nuclear powered ballistic missile submarines armed with long range nuclear intercontinental ballistic missiles provide an invisible deterrent.
Unlike 1914 today all navies take the submarine threat seriously. Should any significant naval war be fought in the Persian Gulf or the Pacific submarines will certainly have an impact not only at sea but in strategic strikes on enemy installations and land based units.
In 1914 no one would have thought that the success of the tiny U-9 would eventually lead to such a dominating weapon.
