The Battle of Leyte Gulf: Sinking the Musashi

IJNS Musashi

This is the second in a series of articles about the Battle of Leyte Gulf.  The first article in the series is liked here and is entitled

The Battle of Leyte Gulf: Introduction and the Battle of Palawan Passage

Following the loss of Atago, Maya and Takao Vice Admiral Takeo Kurita’s Center Force had an uneventful rest of the day on the 23rd as his ships kept a watchful eye and ear for more US Navy submarines.  At about 0800 on 24 October the Center Force was spotted by 3 B-24 Liberator bombers which promptly reported them.

TBF Avenger dropping its “fish” 19 would hit Musashi

One of the ships in the Center Force was the IJNS Musashi, sister ship of the mighty Yamato which was also in the force. The two battlewagons were the largest battleships ever built.  With a full load displacement of 72,800 tons and an armament of nine 18.1 inch guns, the largest battery ever mounted on a warship the two behemoths also had massive anti-aircraft batteries and the Japanese were counting on them leading the Center Force to a miraculous victory during the battle.  Admiral Kurita addressed his commanders prior to the battle:

“I know that many of you are strongly opposed to this assignment.  But the war situation is far more critical than any of you can possibly know.  Would it not be shameful to have the fleet remain intact while our nation perishes?  I believe that the Imperial General Headquarters is giving us a glorious opportunity.  Because I realize how very serious the war situation actually is, I am willing to accept even this ultimate assignment to storm into Leyte Gulf.  You must all remember that there are such things as miracles.”

Musashi or Yamato under attack October 24th 1944

At 1000 the Musashi’s radar picked up approaching aircraft.  These were from the USS Intrepid and the USS Cabot which were assigned to Rear Admiral Gerard Bogan’s Task Group 38.4. The anti-aircraft crews and damage control teams prepared as the ship’s bugle sounded the alarm.  As the aircraft came closer the main guns of the Musashi fired but ceased fire as the aircraft drew closer.  Helldiver dive bombers plunged downward at the ships of the Center Force and F6F Hellcat fighters unopposed by enemy fighters conducted strafing runs as TBF Avenger torpedo bombers dropped their deadly loads at the Musashi.  The big ship avoided two of the “fish” but a third struck causing little damage and the first wave few away.  Musashi reported that she had sustained a hit and continued on.  The Japanese sailors knew that this would not be the last attack.  Though Musashi had weathered the first strike the American fliers hit the battleships Nagato, Yamato and severely damaged the heavy cruiser Myōkō.

Musashi hit

At 1140 the Musashi’s radar picked up the next wave of attackers and at 1203.  These were from the Intrepid, Essex and Lexington.  Hitting the Center Force in two waves a half hour apart these aircraft delivered punishing blows on Musashi. She was hit by 3 torpedoes and 2 bombs. The torpedoes caused damage that caused a 5 degree list and was down six feet by the bow. The torpedo damage was concentrated midships and one torpedo flooded her number 4 engine room. One of the bombs hit an engine room and disabled her port inline propeller shaft.  With her speed reduced she proceeded on.

Musashi

Thirty minutes following this attack at about 1330 Musashi was attacked again by Helldivers and Avengers. She is hit by 4 1000 pound bombs and 4 torpedoes.  She was now so badly damage that she could no longer keep up with the fleet and dropped behind to fend for herself.  At 1350 this attack ends with her speed reduced to 20 knots and with her down 13 feet by the bow and nearly all of her trim and void tanks full. There is now little room for any more damage forward.

Separated from the fleet Musashi was now attacked by aircraft from the Enterprise, Cabot, Franklin and Intrepid that score hits with 11 bombs including the deadly 1000 pounders and 8 torpedoes.  During the course of these attacks which ended after 1530 Musashi sustained 19 torpedo and 17 bomb hits and taken 18 near hits close aboard. At 1620 her skipper Rear Admiral Toshihira Inoguchi began desperate damage control measures to control the increasing list which had reached 10 degrees to port.  Dead in the water she continued to list further and when the list reached 12 degrees at 1915 Inoguchi ordered preparations to abandon ship.  The surviving crew assembled on the deck, the battle flag and the Emperor’s portrait were removed.  Admiral Inoguchi gave his personal notebook to his Executive officer Captain Kenkichi Kato and directed then him to abandon ship. Admiral Inoguchi retired to his cabin and was not seen again.  At 1930 with the list now 30 degrees Captain Kato gave the order to abandon ship and soon with the list increasing further men began to slide across the decks being crushed in the process.  Panic broke out among the crew which had been assembled by divisions and Captain Kato ordered “every man for himself.”  At 1936 the ship capsized and port and went down by the bow sinking in 4,430 feet of water in the Visayan Sea at 13-07N, 122-32E.

The destroyers Kiyoshimo, Isokaze and Hamakaze rescued 1,376 survivors including Captain Kato, but 1,023 of Musashi’s 2,399 man crew were lost including her skipper, Rear Admiral Inoguchi who was promoted Vice Admiral, posthumously.

The rest of the Center Force under Kurita turned around to get out of range of the aircraft, passing the crippled Musashi as his force retreated. Kurita’s retreat was temporary and Kurita waited until 17:15 before turning around again to head for the San Bernardino Strait hoping to find it empty of American ships.  His force was still battle worthy because the majority of the 259 sorties were directed on Musashi and the Heavy Cruiser Myōkō which retired heavily damaged. The Southern Force which had also been hit by American carrier air strikes also continued its push toward Surigao Strait.  The Battle of Surigao Strait, the revenge of the Pearl Harbor Battleships will be the next article in this series.

The Battle of Leyte Gulf: Introduction and the Battle of Palawan Passage

This is the first of a four article series on the Battle of Letye Gulf. The battle was the largest in history both in terms of the number of ships involved and the amount of area covered. The action was triggered by the American invasion of the Philippines causing the Japanese to initiate their Shō-Gō 1 (Victory Plan 1) to attempt to defeat the Americans.  The plan relied heavily on land based air power which most of unfortunately for the Japanese was destroyed during the American carrier air strikes on Formosa earlier in the month. 

The battle was necessitated by the absolute need for the Japanese to hold the Philippines and defeat the Americans at all costs. As Admiral Soemu Toyoda the Chief of the Combined Fleet explained under interrogation after the war

Should we lose in the Philippines operations, even though the fleet should be left, the shipping lane to the south would be completely cut off so that the fleet, if it should come back to Japanese waters, could not obtain its fuel supply. If it should remain in southern waters, it could not receive supplies of ammunition and arms. There would be no sense in saving the fleet at the expense of the loss of the Philippines.

The battle was comprised of 5 battles, the Battle of Palawan Passage, the Battle of the Sibuyan Sea, the Battle of Surigao Strait, the Battle of Cape Engaño and the Battle off Samar. All told about 70 Japanese warships and 210 American and Australian ships were engaged.  A further 300 Japanese aircraft, mostly land based and 1500 American carrier aircraft took part in the battle.  The Japanese order of battle included 1 Fleet and 3 Light Fleet Carriers with a minimal air group, 9 Battleships including the two largest ever built the Yamato and Musashi, 14 Heavy and 6 Light Cruisers and about 3 destroyers.  They were divided into four task forces, the Northern Force under the command of Vice-Admiral Jisaburō Ozawa which had all of the Carriers including the last surviving carrier of the Pearl Harbor attack the Fleet Carrier Zuikaku plus the converted hybrid Battleships Ise and Hyuga; the Southern Force which was two distinct and independent task forces under the command of Vice Admirals Shoji Nishimura and Kiyohide Shima and was built around the ancient battleships Fuso and Yamashiro and 3 Heavy Cruisers; and the Center Force under the command of Vice Admiral Takeo Kurita which had the Battleships Yamato, Musashi, Nagato, Kongo and Haruna, 10 Heavy and 2 Light Cruisers and 1 destroyers.  The Center force was to pass through the San Bernardino Strait and converge on the American landing forces off Samar with the Southern Force which as to come through the Surigo Strait.  The Japanese also planned for the first use of Kamikazes as part of the action. 

Takao Class Cruiser 1943

Atago

The American fleet was comprised of the 3rd Fleet under Admiral William Halsey which was built around the Fast Carrier Task Forces and Fast Battleships of Task Force 38 under the Command of Vice Admiral Marc Mitscher and the Battle Line Task Force 34 under the Command of Vice Admiral Willis Lee; and the 7th Fleet under Vice Admiral William Kinkaid which was the naval support for the landings.  It had under its control the old Battleships West Virginia, California, Tennessee, Maryland, Colorado and Pennsylvania and 18 Escort Carriers which provided the close air support for the Invasion.  All told the Americans had 8 Fleet and 8 Light Fleet Carriers, 18 Escort Carriers, 12 Battleships, 24 Cruisers and 141 Destroyers as well as submarines, PT Boats, Transports, Landing Ships and Auxiliaries.

Takao

This series will focus on a number of individual battles and decisions in the battle. Part one will focus on the action of the Submarines Darter and Dace against the Center force in the Palawan Passage. The next will be the sinking of the Musashi during the Battle of the Sibuyan Sea, it will be followed by the revenge of the Old Battleships at Surigo Strait. The next will be the great decision of Admiral Halsey to pursue the Northern Force and leave the San Bernardino Strait unguarded, followed by the Battle off Samar and last the death of the Japanese Naval Aviation at Cape Engaño.

The Battle of Palawan Passage

Admiral Takeo Kurita and the powerful Center Force departed their anchorage at Bruneion 20 October 1944.  The task force entered the Palawan Passage on the night of 22-23 October where they were sighted by the American Submarines Darter and Dace which had been posted at the strait for such a possibility.  Darter made radar contact at 30,000 yards at 0018 hours on the 23rd and sent out contact reports.   The two submarines shadowed the Center Force on the surface to gain an intercept position and submerged just before dawn.

USS Darter

Darter struck first at 0524 firing a spread of 6 torpedoes scoring 4 hits on Admiral Kurita’s flagship the Heavy Cruiser Atago. She reloaded and stuck the Heavy Cruiser Takao with 2 torpedoes at 0634.  At 0554 Dace hit the Heavy Cruiser Maya with 4 torpedoes.

Vice Admiral Takeo Kurita

The blow was severe.  Atago was mortally wounded she capsized and sank at 0553 with the loss of 360 crew members. She sank so rapidly that Kurita had to swim and was rescued with his Chief of Staff by a destroyer, but many of his staff members were lost with the ship.  Though Kurita transferred his flag to Yamato he was now without the advice and counsel of officers that might have prevented later mistakes during the Battle off Samar.  Takao suffered heavy damage and though she did not sink she had to proceed crippled to Singapore under the guard of two destroyers. Though she survived the war she never saw action again.   Maya, struck at 0554 by 4 torpedoes suffered much damage and was wracked by powerful secondary explosions.  By 0600 she was dead in the water and sank five minutes later with the loss of 337 crew members.

USS Dace

The attack of the two submarines was significant; the Japanese lost 3 powerful Heavy Cruisers and had to send two of their destroyers away to guard Takao. Likewise the loss of Kurita’s experienced staff hindered his conduct of the battle on the 24th.  The cruisers were a big loss, at 13,000 tons and armed with ten 8”guns they could steam at 35 knots.

Darter and Dace conducted a pursuit of the crippled Takao which had to be broken off when Darter ran aground on Bombay Shoal. Despite the best efforts of her crew and that of the Dace to free her she was hopelessly stuck.  Her crew was unable to scuttle her and the Japanese were able to board her after she was abandoned and for the first time get a look at the details of a Gato class submarine.

Kurita’s force would continue on into theSibuyan Seawhere they would be attacked again.  But that is the subject of the next article.

An Invincible Fleet and a Flawed Plan: The Japanese at Midway

Note: This is the first of a series of articles coming over the next few days about the Battle of Midway, a major turning point of the Second World War.

The Battleship Yamato, Flagship of the Combined Fleet and symbol of Japanese Naval Power

The Imperial Japanese Navy under the command of Admiral Isoruku Yamamoto had been humiliated. On April 18th 1942 16 B-25 bombers under the command of Colonel Jimmy Doolittle were launched from the deck of the USS Hornet and bombed Tokyo.  Though the physical damage was insignificant the psychological impact was massive on the Japanese military establishment. Yamamoto and his deputy Rear Admiral Matome Ugaki had explored the possibility of attacking Midway in the early months of 1942 as the Japanese armed forces competed with each other to determine an overall strategy for the war effort. The Army was insistent on a China strategy while the Navy preferred expansion in the Western, South and Central Pacific.  Yamamoto’s idea envisioned seizing Midway and using it as a forward base from which an invasion of Hawaii could be mounted as well as the bait to draw the carrier task forces of the U.S. Navy into battle and destroy them.

Admiral Isoruku Yamamoto, CinC Combined Fleet

The Japanese certainly had the forces to accomplish the mission outnumbering the U.S. Navy which had taken heavy losses at Pearl Harbor and in the Far East.  Following the Doolittle raid Yamamoto went ahead with the plan to invade Midway. The operation, named MI was coupled with an invasion of the islands of Attu and Kiska in the Aleutians which would form a picket line to prevent future attacks on the Japanese mainland. Fuchida

Yamamoto’s plan was not without its critics, the majority of the Staf of the First Air Fleet embarked on the First Carrier Striking Force was not in favor including the leader of the Pearl Harbor attack Commander Mitsuo Fuchida who considered it “grammar school strategy.”   Despite objections from them as well as his Fleet Operations Officer Yamamoto directed that the plan be implemented.  The plan was to have the First Carrier Striking Force attack Midway and reduce its defenses so that the Invasion Force could undertake the task of invading and occupying Midway.  Supporting these forces was the Main Body built around Battleship Division One included Yamamoto’s flagship the 72,000 ton behemoth Yamato.  Another strong force was assigned to the Aleutian operation. The task forces were spread out across the North Pacific and would not able to provide mutual support to each other in a timely manner.

Japanese Forces were organized in the following manner.

It was Yamamoto’s plan to use this force to polish off U.S. Forces that would only enter the fight after he had taken Midway. Despite the success of his carrier task forces at his heart Yamamoto was still a Battleship Sailor and believed that his battleships would be the deciding factor in the final destruction of the U.S. Navy forces in the Pacific.  This force could be augmented by the Aleutian Guard Force, detached from the Main Body under the command of Vice Admiral Shiru Takasu and was composed of the following fleet units:

The force that was the true heart of the Japanese Navy in early 1942 was the First Carrier Striking Force which at Pearl Harbor and in the months following had run roughshod over all Allied opposition.  Initially composed of 6 flattops the force was reduced to four when the Shokaku was heavily damaged and Zuikaku’s air group decimated at the Battle of the Coral Sea on 8 May 1942.  Nevertheless it was still a formidable and experienced force in its own right.  Commanded by Vice Admiral Chuichi Nagumo it was composed of the following units:

Note all Japanese Fleet information obtained online at http://www.microworks.net/pacific/orders_of_battle/midway_japan.htm

These forces were augmented by a submarine screening force and land based naval air forces stationed at Wake and Kwajalein.

The plan was complicated and depended on the Americans reacting exactly as the plan anticipated them doing.  Yamamoto never expected that the Americans would be waiting for his forces and had knowledge of his plans due to the efforts of U.S. Navy code breakers under the direction of Commander Joseph Rochefort and the Fleet Intelligence Officer Captain Edwin Layton had broken the top secret Japanese Navy JN-25 Code.  Thus despite the massive amount of forces involved the plan was seriously flawed and left the advanced forces vulnerable to unexpected American moves.
