The day the Kaiser Sank the Entire Liberian Fleet

Some 105 years ago today, a German submarine, SM U-154, under the command of Kplt. Hermann Gercke, appeared off the Liberian capital of Monrovia and bombarded the city then sank the West African republic’s sole naval vessel.

U-154 was one of the big German Type U 151 merchant submarines built to run the British blockade in the Great War. Converted for use by the Kaiserliche Marine, she mounted two large 5.9″ L/45 deck guns, and another pair of 3.5″ L30s, and carried 18 torpedos.

The event was live-streamed by Richard Bundy, U.S. Chargé in Liberia, as told in three cables:

Monrovia , April 10, 1918 .
[Received 9.07 p.m.]

German submarine now in harbor of Monrovia. Commander sent President, Liberia, following letter this morning:

Sir: I have not the wish to do unnecessary damage to the Liberian people, being sure that you were driven into the war against your true interest; therefore I send you back those prisoners I made beating your armed ship President [ Howard? ]. In the same time I want to draw your attention to the fact that the capital of Liberia is at present helpless under German guns. Like many other allies of England and France you are not being supported by them in the moment of the most critical danger. If the wireless and cable station of Monrovia do not at once cease their work I shall regret being obliged to open fire on them. If you wish to avoid this you will have to send on to me a boat under a flag of truce and declare that you consent to stop them yourself. [Your obedient] servant, Gercke, Kapitan Lieutenant and Commandant S.M.U. Kreuzer U.

Liberian Government has not yet given its final answer to these demands but in any case it looks as if the wireless and cable stations at Monrovia will be put out of commission accordingly. This is probably the last message I will be able to send the Department. It [Page 741]is urgently requested that assistance be sent at earliest possible moment.

Monrovia , April 10, 1918 .
[Received 9.17 p.m.]
Liberian Government agreed to stop operation of wireless and cable stations and in reply to its communications commander of submarine makes following demands:

Extreme urgence, dernier ultimatum. Have the honour to acknowledge the receipt of your answer to my note from this morning. Being sure of your earnest good will to comply with my demands I will not open fire on the cable and wireless stations which I was in the act of doing when just in time your boat was sent out. I am glad to be able to do so because my gun fire might have hurt innocent people. In answer for this I must put to you the following demands:

(1) The French flag is to be removed from its place shown to your commissioners;
(2) Fire is to be set on all houses belonging to the wireless and cable stations, the apparatus of each station to be destroyed;
(3) One and two to be executed within one hour after your commissioners have reached the shore.

I have the honor to be, Sir, your obedient servant, Gercke, Kapitan Lieutenant and Commandant S.M.U. Kreuzer U.

Liberian Government has not yet given its final answer to these demands but in any case it looks as if the wireless and cable stations at Monrovia will be put out of commission accordingly. This is probably the last message I will be able to send the Department. It is urgently requested that assistance be sent at the earliest possible moment.

Monrovia , April 10, 1918 .
[Received April 11, 4 a.m.]
Liberian Government’s final reply to demands of submarine commander was considered unsatisfactory by him. At about 4 this afternoon submarine bombarded French wireless station rendering it inoperative. As result bombardment two Liberian persons killed and two wounded. Submarine is now engaging merchant steamer off Monrovia, result as yet not known. No public disorder. Believe submarine will return to complete demolition of cable and wireless station.

The naval combat between the Germans and Liberians saw U-154 easily dispatch the former I. W. West trading schooner R.L.S President Daniel E. Howard. The 73-ton converted gunboat took 26 of her crew to the bottom (although German accounts say the crew was paroled and not harmed).

The arrival that afternoon of an armed British merchantman, the 3,800-ton SS Burutu, which soon started firing at U-154, drove the German away. Two members of the Burutu’s crew were killed in the surface action. 

What triggered the U-boat onslaught was Liberia’s declaration of war on Imperial Germany the previous August. Prior to that event, the republic had a good relationship with Berlin, as the country was one of the four guaranteers of a $1.7 million load handled by a New York bank in 1912. Pre-war, the port facility at Monrovia was largely run by German firms, and something like 75 percent of the country’s overseas trade went back and forth to Hamburg.

Following the raid, Gercke was wired that he was promoted to Korvettenkapitän on 28 April for his performance, which besides the Liberian affair had seen him sink four other ships.

Two weeks later, U-154 was found and sunk by HM Submarine E-35 off the coast of West Africa, taking all 77 hands, KKpt Gercke included, to the bottom.

As far as Burutu, the Captain, Henry A. Yardley, was awarded the Distinguished Service Order and Seaman Edward Jones was given a gold medal by the passengers. The Dempster Lines cargo vessel would be sunk in a collision with the 7,000-ton City of Calcutta in the Irish Sea during a convoy mix-up in October 1918. She went down with all 160 aboard.
