- Twenty-two miles northwest of Amami-O-Shima, submarine USS Spearfish detected a Japanese destroyer of a previously unknown type. Spearfish fired three Mark 18 electric torpedoes with no hits. As the torpedoes were still making their run, the destroyer turned and counter-attacked Spearfish. Spearfish went deep and endured a very well executed depth charge attack involving 18 depth charges. Spearfish sustained moderate but repairable damage. ww2dbase [Spearfish | East China Sea | DS]

- In the East China Sea, submarine USS Spearfish detected a Japanese convoy of about ten cargo ships with three escorts. Spearfish fired four torpedoes into the pack of ships and four more at the merchant ship Toyoura Maru, whose cargo of high explosives disintegrated the ship with a brilliant flash. The first torpedo salvo also damaged the munitions ship Mamiya. Spearfish then endured a depth charge attack that considerably shook the boat with each of the eleven explosions. Once Spearfish evaded the counter-attack, she circled back to find Mamiya dead in the water. Spearfish executed another torpedo attack that further damaged the ship and subjected Spearfish to another boat-jarring depth charge attack. ww2dbase [Spearfish | East China Sea | DS]
