  • In the Battle off Samar in the Battle of Leyte Gulf, destroyers USS Hoel and Heerman launched three Mark XV torpedoes at two different Japanese cruisers and missed. The torpedoes went on to advance on the battleship Yamato, the Japanese force flagship. Yamato’s evasive action took the force commander, Admiral Takeo Kurita, so far from the action that he effectively lost his ability to command the battle and likely contributed to his ultimate decision to break off the engagement and withdraw his force. ww2dbase [Philippines Campaign, Phase 1, the Leyte Campaign | Mark XV | Hoel | Yamato | Takeo Kurita | Philippine Sea | DS]
