SM UC-38

SM UC-38 was a German Type UC II minelaying submarine or U-boat in the German Imperial Navy (Kaiserliche Marine) during World War I. The U-boat was ordered on 20 November 1915 and was launched on 25 June 1916. She was commissioned into the German Imperial Navy on 26 October 1916 as SM UC-38. In 9 patrols UC-38 was credited with sinking 40 ships, either by torpedo or by mines laid.

On 14 December 1917, by 38.25°N, 20.36667°W, under Hans Hermann Wendlandt, UC-38 met a French convoy comprising the fast cruiser Chateaurenault, serving as a troopship, and her escorts Mameluk, Rouen and Lansquenet. UC-38 approached and fired one torpedo on Chateaurenault, which was hit in her middle section at 6:47. UC-38 dived at 38 metres, while the Mameluk and Rouen rushed to the launching position of the torpedo, and Lansquenet started picking up people thrown overboard by the explosion. Chateaurenault requested her escorts to close in and evacuate personnel, which was completed by 07:26. The trawler Balsamine came to the rescue and made attempts to take Chateaurenault in tow.

Back to periscope depth, UC-38 saw Chateaurenault still afloat, and fired a second torpedo, which hit at 8:20; Chateaurenault foundered quickly, but all personnel still alive aboard could be rescued. Lansquenet, in the process of picking up her launches, rushed to the launching point and fired 7 depth charges. One caused a light leak in the submarine; captain Wendlandt ordered a dive to bring his ship below the area targeted by the grenades, but a false manœuvre made UC-38 climb instead, and a second explosion caused a large leak, forcing Wendlandt to crash surface and abandon ship.

UC-38 surfaced briefly and was immediately targeted by the guns of Mameluk, which continued her attack by launching several depth charges. UC-38 surfaced again, and this time both Mameluk and Lansquenet opened fire, hitting her several times and killing several of her crew as they exited. She sank at 8:40, and the French destroyers picked up the survivors.

German sources claim that 25 men were rescued and 9 killed; a sailor of UC-38 claimed that 20 men were saved out of a 28-man crew; French enquiry reports 20 rescued and 5 confirmed dead out of a 27-man crew.
