Convoy SC-118 was the 118th of the numbered series of World War II Slow Convoys of merchant ships from Sydney, Cape Breton Island to Liverpool.[1] The ships departed New York City on 24 January 1943[2] and were met by Mid-Ocean Escort Force Group B-2 consisting of V class destroyers Vanessa and Vimy, the USCG Treasury Class Cutter Bibb, the Town class destroyer Beverley, Flower class corvettes Campanula, Mignonette, Abelia and Lobelia, and the convoy rescue ship Toward.[3]


As western Atlantic coastal convoys brought an end to the second happy time, Admiral Karl Dönitz, the Befehlshaber der U-Boote (BdU) or commander in chief of U-Boats, shifted focus to the mid-Atlantic to avoid aircraft patrols. Although convoy routing was less predictable in the mid-ocean, Dönitz anticipated that the increased numbers of U-boats being produced would be able to effectively search for convoys with the advantage of intelligence gained through B-Dienst decryption of British Naval Cypher Number 3.[4] However, only 20 percent of the 180 trans-Atlantic convoys sailing from the end of July 1942 until the end of April 1943 lost ships to U-boat attack.[5]

On 2 February U-456 sank three ships from convoy HX 224. A survivor of one of the sunken ships was picked up by U-632 and told his rescuers a slower convoy was following behind HX-224.[6]


A careless merchant seaman of convoy SC-118 accidentally fired a pyrotechnic snowflake projector aboard SS Annik in the pre-dawn darkness of 4 February.[6] U-187 observed the snowflake display, reported sighting the convoy, and was promptly sunk by Beverly and Vimy after Bibb and Toward triangulated her location from the sighting report, using High-Frequency radio Direction-Finder (HF/DF or Huff-Duff).[3] The destroyers rescued 44 of the submarine's crew.[7] The Polish freighter Zagloba was torpedoed on the unprotected side of the convoy by U-262 and U-413 torpedoed the straggling American freighter West Portal.[3]

On 5 February the convoy escort was reinforced by the USCG Treasury Class Cutter Ingham and the Wickes class destroyers Babbitt and Schenck from Iceland.[3] The reinforced escort damaged U-262 and U-267.[8]

In the pre-dawn hours of 7 February, U-boat Ace Kapitänleutnant Siegfried von Forstner's U-402 torpedoed the British freighter Afrika, Norwegian tanker Daghild, Greek freighter Kalliopi, American tanker Robert E. Hopkins, American cargo liner Henry R. Mallory, and Convoy rescue ship Toward.[9]

Henry R. Mallory was capable of 14 knots but had been straggling well astern of the convoy for several days and was not zig-zagging in that exposed position.[10] Mallory would normally have been assigned to one of the faster HX convoys, but there had been no Iceland section of the preceding convoy HX-224.[10] No commands came from the bridge after Mallory was torpedoed, no flares were sent up, no radio distress message was sent out, and no orders were given to abandon ship.[11] There were heavy casualties from Mallory's crew of 77, 34 Navy gunners, and the 136 American soldiers, 172 American sailors, and 72 American Marines she was transporting to Iceland.[12]

U-614 sank the straggling British freighter Harmala[9] while Lobelia sank U-609.[3]

B-17 Flying Fortress J of No. 220 Squadron RAF sank U-614 on 7 February.[3] U-402 sank British freighter Newton Ash that night. On 9 February Kapitänleutnant von Forstner was awarded the Knight's Cross of the Iron Cross for ships sunk by U-402 from this convoy and from Convoy SC-107 on the previous patrol. SC-118 reached Liverpool without further loss on 12 February.[2]
