At 0031, Rear Admiral (later Vice Admiral) Aaron S. Merrill (former CO of INDIANA, BB-58) intercepts the Japanese with his Task Force 39's CruDiv 12's radar-equipped light cruisers USS CLEVELAND (CL-55), COLUMBIA (CL-56), MONTPELIER (CL-57) and DENVER (CL-58), Captain (later Admiral/CNO) "31 knot" Arleigh Burke's destroyers USS STANLY (DD-478), CHARLES F. AUSBURNE (DD-570), CLAXTON (DD-571) and DYSON (DD-572) and Cdr B. L Austin's CONVERSE (DD-509), FOOTE (DD-511), SPENCE (DD-512) and THATCHER (DD-514).
At 0040, HAGURO's floatplane spots several American warships 20 mile S of Omori's force. At that same time, Captain Burke's four van destroyers launch 25 Mark-15 steam torpedoes at Omori's force.
At 0045, lookouts on SHIGURE spot the American destroyers at 7,500 yards. SHIGURE turns hard starboard and launches eight torpedoes towards them. SENDAI also turns hard starboard, but bears down on SHIGURE. SHIGURE barely avoids a collision with SENDAI, but the following SAMIDARE side-swipes SHIRATSUYU and crushes her hull portside.
At 0050, all four of Merrill's cruisers take SENDAI under radar directed 6-inch fire. They hit her with their first salvo and more thereafter setting her afire.
About 0100, Omori's flagship MYOKO collides with HATSUKAZE and the destroyer loses her bow. At 0108, American destroyer FOOTE is hit by a torpedo and damaged heavily, but does not sink.
At 0115, MYOKO and HAGURO are straddled by American shells. Both cruisers open fire blindly and launch 24 torpedoes in the direction of Merrill's forces. In the next 20 minutes, HAGURO takes about ten hits from 5-inch and 6-inch shells, but most are duds and the damage is minor.
At 0134, Vice Admiral Omori orders the withdrawl of the remaining Japanese forces. He signals Rabaul and requests a submarine be dispatched to rescue survivors. At 0200, SENDAI is abandoned. ComDesRon 3 Rear Admiral Ijuin enters the water. 236 other SENDAI crewmen are rescued by destroyers.
Burke's destroyers finish off HATSUKAZE by gunfire. She goes down with all 240 hands.
SENDAI remains afloat until 0430 when she sinks at 06-10S, 154-20E. Captain Shoji and 184 crewmen go down with her.
Captain Shoji is promoted Rear Admiral, posthumously.

Removed from the Navy List.
 On 12 June 2002, Dutch divers of the International Association for Handicapped Divers locate the wreck of O-20 about 35 miles NE of Kota Bharu, Malaysia at a depth of 144 feet.
 Dubbed "Bloody Ridge", it is later renamed "Edson's Ridge" in honor of LtCol (later MajGen/MOH) Merritt A. Edson, CO of the First Marine Raider Battalion that held the ridge against repeated assaults by MajGen Kawaguchi Kiyotake's 6,000-man Brigade attempting to retake Henderson Field.
 On 3 Nov 43, Rear Admiral Ijuin and 75 survivors from SENDAI are rescued by LtCdr Shoda Keiji's submarine RO-104.
Special thanks for assistance in researching the IJN officers mentioned in this TROM go to Aldert Gritter/"Adm. Gurita" of the Netherlands and Mr. Jean-François Masson of Canada.
