Leyte campaign, November-December 1944.
Template:Campaignbox Philippines, 1944-45

The Battle of Ormoc Bay was a series of air-sea battles between Imperial Japan and the United States in the Camotes Sea in the Philippines between 11 November 1944 and 21 December 1944, part of the Battle of Leyte in the Pacific campaign of World War II. The battles resulted from Japanese operations to reinforce and resupply their forces on Leyte and US attempts to interdict them.

Background

After gaining naval control over the Western Pacific in mid-1944, the United States and the Allies of World War II attacked the Philippines in October, landing troops at Leyte Gulf on the east side of Leyte on 20 October 1944. The island of Leyte was at that point defended by about 20,000 Japanese; the American general, Douglas MacArthur, thought that the occupation of Leyte would be only a prelude to the major engagement on Luzon. For the Japanese, maintaining control of the Philippines was essential because their loss would enable the Allies to sever their oil supply line from Borneo.

The Imperial Japanese Navy responded to this attack with a combined fleet attack that led to the Battle of Leyte Gulf between 23 October and 26 October. In this massive naval engagement, the Japanese Navy was destroyed as a strategic force. However, this was not at first clear, and the Japanese commander in the Philippines, General Tomoyuki Yamashita, believed that the United States Navy had suffered severe casualties and that the Allied land forces might be vulnerable. Accordingly, he began to reinforce and resupply the garrisons on Leyte; over the course of the battle the Japanese ran nine convoys to the island, landing around 34,000 troops from the 1st, 8th, 26th, 30th, and 102nd divisions. Ormoc City at the head of Ormoc Bay on the west side of Leyte was the main port on the island and the main destination of the convoys.

Decryption of messages sent using the PURPLE cipher alerted the Allies to the concentration of Japanese shipping around Leyte, but they initially interpreted this as an evacuation. However, by the first week of November the picture was clear and the Allies began to interdict the convoys.

Operations

TA-3 and TA-4 (Japanese)

On 8 and 9 November, the Japanese dispatched two convoys from Manila to Ormoc Bay. The convoys were spaced one day apart so that the destroyers escorting the first convoy could double back and escort the second. However, the convoys were spotted by planes from the U.S. 3rd Fleet and Admiral William F. Halsey ordered an attack by 350 planes of Task Force 38 on the combined convoys on 11 November.

Four destroyers — Shimakaze, Wakatsuki, Hamanami, Naganami — and five transports were sunk. Rear Admiral Mikio Hayakawa went down with Shimakaze.

TA-5 (Japanese)

Convoy TA-5 left Manila on 23 November for Port Cataingan and Port Balancan. Of the six transports, five were sunk by air attack.<ref name="convoys" />

U.S. destroyer sweeps

Bad weather in late November made air interdiction less effective and the U.S. Navy began to send destroyers into Ormoc Bay. Canigao Channel was swept for mines by Pursuit and Revenge, and the four destroyers of Destroyer Squadron 22 (DesRon 22) under the command of Captain Robert H. Smith (Waller, Pringle, Renshaw and Saufley) entered the bay, where they shelled the docks at Ormoc City.

An Allied patrol plane radioed a message to the division noting that a surfaced Japanese submarine (the I-46) was south of Pacijan Island and heading for Ormoc Bay. The division headed south to intercept; and, at 01:27 on 28 November, Waller's radar picked up the target just off the northeast coast of Ponson Island. Waller disabled the submarine with her first shots and, unable to submerge, I-46 could only return fire with her deck guns until she sank at 01:45.

TA-6 (Japanese)

Two transports escorted by three patrol vessels left Manila on 27 November. They were attacked by American PT boats in Ormoc Bay on the night of 28 November and by air attack as the survivors left the area. All five ships were sunk.<ref name="convoys" />

Another US destroyer sweep on the night of 29–30 November in search of a reported convoy resulted only in the destruction of a few barges.

TA-7 (Japanese)

A convoy of three transports departed Manila on 1 December, escorted by destroyers Take and Kuwa under the command of Lieutenant Commander Masamichi Yamashita. Two groups of transport submarines also took part in the operation.

On the night of 2–3 December the convoy was docked at Ormoc City when it was engaged at 00:09 by three ships of US Destroyer Division 120 (DesDiv 120) under the command of Captain John C. Zahm (Allen M. Sumner, Cooper and Moale).

The US ships sank the transports as they were unloaded but came under heavy attack from Yokosuka P1Y "Frances" bombers, shore batteries, submarines that were known to be in the harbor, and the Japanese destroyers. Kuwa was sunk and Commander Yamashita was killed. Take attacked Cooper with torpedoes and escaped, though with some damage. Cooper sank at about 00:15 on 3 December with the loss of 191 lives (168 sailors were rescued from the water on 4 December by PBY Catalina planes). At 00:33 the two surviving US destroyers were ordered to leave the bay. The 2-3 December phase of the Battle of Ormoc Bay has gone down in history as the only naval engagement during the war in which the enemy brought to bear every type weapon: naval gunnery, air attack, submarine attack, shore gunnery and mines.

On 5 December 1944 US Marines made a landing at San Pedro Bay, 27 miles south of Ormoc City. The landing craft and support vessels came under sustained kamikaze air attack. Fifteen craft were sunk, and destroyers Mugford and Drayton were hit, suffering about 50 casualties.

On 7 December 1944 the 77th Infantry Division, commanded by Major General Andrew D. Bruce made an amphibious landing at Albuera, three and a half miles south of Ormoc City. The 77th Division's 305th, 306th, and 307th Infantry Regiments came ashore unopposed but naval shipping was subjected to kamikaze air attacks, resulting in the loss of destroyers Ward and Mahan.<ref name="anderson" />

Other operations

All five transports of convoy TA-8 were sunk on 7 November by air attack, and the escorting destroyers Ume and Sugi were damaged.

Convoy TA-9 entered the bay on 11 December and landed troops, but two escorting destroyers, Juzuki and Uzuki, were sunk and the third, Kiri, was damaged.<ref name="convoys" />

Significance

By fighting this series of engagements in Ormoc Bay, the US Navy was eventually able to prevent the Japanese from further resupplying and reinforcing their troops on Leyte, contributing significantly to the victory in the land battle. The final tally of ships lost in Ormoc Bay is: U.S. — 3 Destroyers and 1 APD (high speed transport) plus 2 LSMs; Japan — 6 Destroyers, 20 small transports, 1 submarine, 1 patrol boat and 3 escort vessels.

Historian Irwin J. Kappes argued that naval historians have unjustly neglected the importance of these engagements, writing:

In the end, it was the rather amorphous Battle of Ormoc Bay that finally brought Leyte and the entire Gulf area under firm Allied control. From 11 November 1944 until 21 December, the combined efforts of Third Fleet carrier planes, Marine fighter-bomber groups, a pincer movement by the Army’s 77th Division and the First Division plus a motley assortment of destroyers, amphibious ships and PT boats trounced the now semi-isolated Japanese in a series of skirmishes and night raids. And because of poor weather conditions air support for most of these surface actions was almost non-existent.
