Before dawn, the floatplane of Japanese submarine I-10 conducted a reconnaissance mission over Diego-Suárez harbor, Madagascar, spotting British battleship HMS Ramillies, a tanker, a freighter, and an ammunition ship. At 1740 hours, I-16 and I-20 launched midget submarines M-16b and M-20b 10 miles from Diego-Suárez. M-20b fired her torpedo at 2025 hours, damaging HMS Ramillies and putting her out of action for a year. At 2120 hours, corvettes HMS Genista and HMS Thyme counterattacked with depth charges but failed to hit the Japanese midget submarines. Shortly after, M-20b fired her second torpedo, sinking British tanker British Loyalty. ww2dbase [Madagascar Campaign | Japanese Midget Submarine Warfare in World War II | Type A-class | Diego-Suárez | AC, CPC]
