At 1.19 PM, U-28 hits the British merchant ship SS Royston Grange (carrying general cargo and grain) with one torpedo. Royston Grange, sailing from Buenos Aires to Liverpool with convoy SL-8B, sinks about 50 miles southwest of Lands End. The crew are rescued by the trawler Romilly and taken to Swansea. U-28 also lays mines in the Bristol Channel on this patrol, which cause the sinking of the 9,577 ton SS Protesilaus on 21 January 1940.
Between 10 PM and midnight, U-43 repeatedly attacks British steamer SS Uskmouth about 120 miles northwest of Cape Finisterre, Spain. Her first 2 torpedoes malfunction and then U-43 shells Uskmouth with her deck gun. At 11 PM, U-43 fires another torpedo which misses. They continue shelling (firing 149 rounds in total) until Uskmouth sinks at midnight. Two men die but the captain and 22 crew are rescued by Italian merchant vessel SS Juventus and landed at Ramsgate on 30 November.
