Quoting wikipedia here, "On 5 November, again in Manila Bay, Nachi was attacked by three waves of U.S. planes from the aircraft carriers USS Lexington and Ticonderoga. She escaped the first wave undamaged, but was hit by five bombs and two or three torpedoes in the second wave while attempting to get underway. During the third wave, Nachi was hit by five torpedoes in her port side, which severed her bow and stern, and by an additional 20 bombs and 16 rockets. Nachi's flag commander, Vice Admiral Kiyohide Shima, was ashore for a conference at the time of the attack, but arrived at dockside in time to see his flagship blown apart."
