USS Petrof Bay

At Pearl Harbor, Petrof Bay disembarked her excess aircraft, and on 12 August, she left port, as a part of Task Group 32, the Western Attack Group, assigned to the Mariana and Palau Islands campaign, but more specifically, to the planned Battle of Peleliu, codenamed Operation Stalemate II. She first headed to Guadalcanal of the Solomon Islands, anchoring in Tulagi Harbor on the afternoon of 24 August. On 4 September, having been assigned to Task Unit 32.7.2, or "Taffy 3", commanded by Rear Admiral George R. Henderson along with her sisters Saginaw Bay, which was Henderson's flagship, and Kalinin Bay, she sortied for the western Caroline Islands as a part of the Peleliu and Anguar Movement Group Number 2, screened by the Fletcher-class destroyers Haggard, Hailey, Johnston, and the Gleaves-class destroyer Welles.[6][12]

Petrof Bay, upon arriving off of Peleliu on 15 September, immediately began launching strikes against Japanese positions on the island. Marines of the 1st Marine Division landed on the southwest beaches of the island on the morning of 15 September, with the aircraft of VC-76 providing crucial close air support as they advanced up the island. For example, on the late afternoon of 15 September, as the Japanese garrison massed for a counterattack, a VC-76 TBM dropped a 500 lb (230 kg) bomb in the midst of three tanks, putting all three out of action.[13] Her aircraft continued supporting the Marines almost continuously until 29 September, with the exception of one day when she replenished on munitions at Kossol Roads. Notably, her aircraft were allowed almost free rein over the island, with the beleaguered Japanese forces in the area never providing any air opposition. By 30 September, the airfield on the island had become operational, enabling the use of land-based aircraft, and therefore Petrof Bay retired back to Manus Island.[12]

Whilst at Manus Island, Petrof Bay was assigned to Task Unit 77.4.1, or "Taffy 1" of Task Group 77.4, the Escort Carrier Group. Commanded by Rear Admiral Thomas L. Sprague, it consisted of the Sangamon-class escort carriers Sangamon, which was Sprague's flagship, Suwannee, Chenango, Santee, as well as the Casablanca-class escort carriers Saginaw Bay and Petrof Bay in Carrier Division 28, subdivided from the other carriers, but still within the same task unit. Carrier Division 28 was commanded by Rear Admiral George R. Henderson, whose flag was still hoisted onboard Saginaw Bay.[7] On 14 October, she sortied from Seeadler Harbor, headed for Leyte Gulf in support of the opening landings on Leyte, which was to be the return of American forces to the Philippines, and which would also begin the Philippines campaign.[12]

As the escort carriers snaked northwards from the Admiralty Islands, they provided air cover and screening for the troop transports underway. Petrof Bay and Saginaw Bay were assigned to escort the transports of Task Group 79.3, which was carrying the troops of the 7th Infantry Division, which was bound to land near Dulag, near the southern flank of the planned initial beachhead. On 20 October, having finished her task of escorting the attack transports, she separated from the rest of "Taffy 1" and rendezvoused with Task Unit 77.4.2, or "Taffy 2" for the initial landings, as "Taffy 2" was responsible for covering the landing of the 7th Infantry Division. Between the two carriers, they made forty air sorties on 20 October, as the 7th Infantry landed on Leyte.[14] She then detached from "Taffy 2" and rejoined "Taffy 1", which had been suffering from Japanese air attacks. Petrof Bay continued providing air support from 21 October to 24 October.[12]

In the meantime, as the escort carriers conducted their strikes, the Japanese garrison on Suluan had managed to alert their command, triggering Admiral Soemu Toyoda to launch Shō-Gō 1, a gambit to defend Japan's access to the oil fields of Southeast Asia.[15] On 24 October, news began filtering through of the Japanese fleet moving out to engage, in what was to be the Battle of Leyte Gulf. Petrof Bay, having rejoined "Taffy 1" (Saginaw Bay had transferred her aircraft contingent to other carriers and retired from the field on 24 October), was located in the southernmost group of the escort carriers, just east of Surigao City. With this news, VC-76 began rearming into a complement more suitable to fighting against surface ships, with Captain Kane ordering all of her TBM Avengers to be loaded with torpedoes, of which they would dearly need the following day.[12][16]

Over the night of 25 October, Vice Admiral Takeo Kurita's Center Force swung through the San Bernardino Strait, confronting and catching "Taffy 3", the northernmost escort carrier group, by surprise as the sun rose. The Center Force had previously been sighted and attacked by aircraft in the Sibuyan Sea, and had been thought to be withdrawing, information which had certainly played into Admiral William Halsey Jr.'s decision to lead his Third Fleet northwards, after spotting Vice Admiral Jisaburō Ozawa's diversionary Northern Force. Thus, the only ships covering the vulnerable landing crafts of Leyte Gulf were the three escort carrier task groups and their screens.[15]

At 06:47, on the morning of 25 October, "Taffy 3" radioed for help, reporting that they were being attacked by a large Japanese surface force. Therefore, "Taffy 1" and "Taffy 2" launched aircraft in relief. As a part of this action, Petrof Bay launched two special strikes against the Center Force, with the first special strike consisting of eight FM-2 Wildcats, which linked with aircraft from Santee and Sangamon to strafe the Japanese fleet. The Wildcats made strafing runs against the Japanese ships, to little effect, and released their bombs, to unknown effect (heavy anti-aircraft fire made immediate observation extremely precarious). Two of her Wildcats were lost in this action, one of them to friendly anti-aircraft fire as it tried to return to Petrof Bay over Tacloban, and another to the flak of the Japanese fleet as it made a run.[12][17]

In this photograph taken from one of Composite Squadron (VC) 76's aircraft, an unidentified Tone-class cruiser of the Center Force is shown firing against attacking planes on 25 October 1944. Note the splashes distributed throughout the water.

In the meantime, the second special strike of "Taffy 1" organized, consisting of forty-one planes, coming into formation at around 07:25. Amongst this contingent were four FM-2 Wildcats and six TBM-1C Avengers launched by Petrof Bay. Immediately after these planes had been launched, at 07:29, radar detected six Japanese Mitsubishi A6M "Zeros" approaching "Taffy 1". As a result, the crew of Petrof Bay were immediately called to general quarters, and would remain so for the next 108 hours. These six planes carried out the first organized kamikaze attacks to take place in the course of the Pacific War. At 07:40, visual contact was made with four of the Zeroes, which were proceeding some 10,000 ft (3,000 m) above the carriers. Three of the kamikazes immediately began their dives, with the fourth loitering around before selecting a target. The first kamikaze struck Santee, and the second kamikaze was shot down just short of Sangamon, spraying shrapnel all over the carrier. The third kamikaze dove towards Petrof Bay, but was shot down by her anti-aircraft guns as it made its dive. Nonetheless, it crashed into the ocean near enough to send water splashing onto her flight deck. The fourth kamikaze, having chosen its target, dove and struck Suwanee. A few minutes later, Santee was hit by a torpedo fired from the Japanese submarine I-56.[12][18]

In the chaos following the immediate aftermath of the kamikaze attacks, a Yokosuka D4Y "Judy" dive bomber dove out of the cloud cover to the port side of Petrof Bay, catching the carrier's crew by surprise. The aircraft strafed the carrier as it dove, and released its bomb unmolested by anti-aircraft fire, which still missed to the carrier's starboard. Thereafter, it disengaged and flew off.[12]

At 09:10, having been delayed considerably by kamikazes attempting to harry "Taffy 1", the special strike group proceeded northwards, reaching the vicinity of the battle at around 10:00. By then, Kurita had been discouraged by the American resistance, and was withdrawing eastwards. Petrof Bay's Avengers made torpedo runs against the battleships Kongō, Haruna, and Nagato, with two Avengers even attempting to strike the largest battleship ever launched, the super battleship Yamato. The crew of VC-76 reported one probable hit on Yamato, two probable hits on Nagato, two hits on Kongō, as well as one hit on an unidentified cruiser. However, the veracity of these claims are certainly dubitable, considering that the Japanese never recorded said torpedo "hits".[12][19]

In the meantime, her Wildcats strafed the Japanese fleet, with apparent greater success than during the first special strike. Remarkably, despite the limited damage inflicted by the second special strike, none of her aircraft were lost to enemy fire. However, as they proceeded back from their strikes, the returning aircraft were dangerously low on fuel. Some of her Wildcats diverted to Tacloban, were they were harried by friendly anti-aircraft fire. In addition, some of her Avengers diverted to Fanshaw Bay of "Taffy 3" and Ommaney Bay of "Taffy 2", with one of her Avengers landing with less than 10 US gal (38 L; 8.3 imp gal) of fuel remaining. Four of her aircraft opted to try to return to Petrof Bay, the two Avengers that had made their run against Yamato, as well as two Wildcats. Three of those aircraft landed on her flight deck successfully, with one of the Avengers being forced to ditch into the ocean within sight of the carrier.[12][20]

At 15:30, Petrof Bay launched a final strike to harass the retreating Center Force. After rendezvousing with the other aircraft of "Taffy 1", the aircraft proceed to the San Bernardino Strait, where it encountered the Mogami-class cruiser Kumano, whereupon her Avengers made torpedo runs against the cruiser. The apparently overeager pilots recorded two torpedo hits and one probable torpedo hit, when in reality the cruiser suffered only minor damage. Her final strike was forced to also divert to Tacloban, as their fuel was insufficient to return to "Taffy 1". Thus, Petrof Bay was left with only two Avengers onboard.[12][21]

At 22:37, "Taffy 1" was steaming towards a rendezvous with "Taffy 3", when one of its escorts, the Buckley-class destroyer escort Coolbaugh, sighted the feathery wake of a submarine's periscope perpendicular to the escort carriers. As Coolbaugh charged in towards the wake to deliver depth charges, with inconclusive results, the rest of the fleet conducted an immediate 90-degree emergency turn. As the turn was completed, the crew of Petrof Bay spotted two torpedo wakes straddling the carrier, one 20 yd (18 m) to the portside, and another apparently coasting under the overhang on the starboard side.[12][22]

Whilst the American forces had been distracted with the Battle off Samar and its immediate aftermath, Vice Admiral Naomasa Sakonju's transport unit, which consisted of the Nagara-class light cruiser Kinu, the Fubuki-class destroyer Uranami, as well as four transports, which were in the process of unloading 2,000 troops onto Ormoc Bay, on the Western coast of Leyte. The transport unit had also previously included the Aoba-class cruiser Aoba, but after having been damaged by the Gato-class submarine Bream on 23 October, it withdrew westwards. The transport unit finished unloading its troops on the morning of 26 October, but as it withdrew, it was quickly sighted. Therefore, a strike group of twenty-three Avengers and twenty-nine fighters were assembled to strike the Japanese ships. Petrof Bay contributed its last two Avengers to the strike group, and the strike group reached the Japanese ships at 10:00 in the morning. One of Petrof Bay's Avengers scored a hit with a 500-pound (230 kg) semi-armor-piercing bomb on Kinu, which sank shortly afterwards. In addition, her fighters strafed Uranami, contributing to her sinking.[12][23]

In a photograph likely taken onboard the flight deck of Petrof Bay, the escort carriers Santee and Suwannee are depicted. The burning carrier is Suwannee, which had been previously hit by two kamikazes.

Whilst the Japanese ships were being harried by the aircraft of "Taffy 1", two kamikaze strike groups took off from Cebu on the morning of 26 October, the first group consisting of two kamikazes and one escort, and the second group consisting of three kamikazes and two escorts. The first group was quickly intercepted by American fighters and all shot down, but the second group proceeded towards "Taffy 1" undetected, only being picked up by radar when it was 35 mi (56 km) away from the fleet. Fighters returning from the attack on the Japanese ships were diverted to intercept the second group, but were distracted by the escorts, enabling the kamikazes to make their runs against the escort carriers. The first kamikaze, apparently intent on diving on Petrof Bay, was shot down by a fighter, whilst the other two kamikazes began making their dives at 12:38. The second kamikaze dove onto, and struck Suwanee, whilst the third kamikaze dove down on Petrof Bay, but it had its tail shot off by intense flak at an elevation of approximately 500 ft (150 m), and it crashed into the sea just 50 ft (15 m) off the stern of Petrof Bay.[12][24]

During the night of 28 October, Petrof Bay retired to refuel, rendezvousing with Taffy 2. On the afternoon of 30 October, Petrof Bay, along with the rest of "Taffy 1", retired for Manus Island. Remarkably, despite the loss of several of her aircraft, and the fact that VC-76 had logged 15,000 flight hours over a period of eight months of active combat, the entirety of the crew of VC-76 survived the Philippines campaign. Seventeen Navy Crosses were awarded amongst the aircrew of VC-76, and Captain Kane also received a Navy Cross.[12][25]

After arriving at Manus, Petrof Bay was assigned to Task Unit 77.4.5, the Reinforcement Carrier Group, and she was yet again under the flag of Rear Admiral Henderson. During her stay at Manus, Captain Ralph Sperry Clarke took over command of the vessel. She departed Manus Harbor on 19 November, arriving in the traffic lanes leading to Leyte on 23 November, whereupon she began operations providing air cover for convoys proceeding to and departing from the Philippines, a task necessary due to the convoys being harassed with irritating frequency by Japanese aircraft based on Mindanao. She continued these operations until the end of the year, when she was detached from Task Group 77.3, and joined up with Task Force 79, Vice Admiral Theodore Stark Wilkinson's Lingayen Attack Force, in support of the Invasion of Lingayen Gulf. She provided air cover for the attack transports of the task force as they proceeded to Lingayen Gulf, and gave close air support as they landed.[26] The task force came under intense kamikaze attack as it proceeded up the South China Sea to northern Luzon, sinking her sister Ommaney Bay on 4 January 1945, and damaging several other carriers. This forced Petrof Bay into assuming double duty, taking on some of their assigned tasks.[27]

On 10 January, Task Unit 77.4.6, the Close Covering Carrier Group was formed under the command of Rear Admiral Henderson, comprising Petrof Bay, Saginaw Bay, and Marcus Island. The group was screened by the destroyers Charrette and Conner, as well as the destroyer escorts Richard S. Bull and Richard M. Rowell.[28] On 17 January, the United States Army Air Forces took over responsibility for air operations over Luzon, and Petrof Bay joined Rear Admiral Russell S. Berkey's fleet operating west of northern Mindoro. On 29 and 30 January, Petrof Bay provided air cover and close air support as the Eighth Army landed at San Narciso and San Antonio, located just to the north of Manila, where they prepared for the Battle of Manila.[12][29]

Upon helping the Eighth Army gain a foothold north of Manila, Petrof Bay retired for Ulithi of the Caroline Islands. Just five days later, she departed Ulithi, this time assigned to Task Unit 52.2.1, under the command of Rear Admiral Clifton Sprague, in preparation for the Battle of Iwo Jima. The Air Force wanted the island base neutralized to eliminate the threat of fighter interceptions, and also because they wanted to use the island as a base to provide fighter escorts for the B-29 Superfortress raids on Tokyo and other assorted Japanese cities. She arrived off of Iwo Jima on 15 February, in company with Task Group 52.19, the Advance Movement Group.[12][9]

Upon arriving, Petrof Bay's air contingent commenced operations over the island, which in conjunction with surface bombardment, aimed to soften the Japanese defenses. On 17 February, one of her Avengers was hit by anti-aircraft fire, and was then subsequently forced to ditch next to a friendly destroyer.[30] On 18 February, the troop transports carrying the Marines arrived offshore, and they landed on Iwo Jima the following day. Throughout the battle, Petrof Bay's aircraft logged 786 air sorties conducted in support of the operation. Notably, on 21 February, the fleet carrier Saratoga was hit by a kamikaze, and Petrof Bay, which was heading to refuel, was recalled back by Vice Admiral Calvin T. Durgin.[12][31]

By 7 March, the airstrip on Iwo Jima had been captured and restored to be fully operational, enabling ground-based aircraft to provide close air support in lieu of the carriers. On 8 March, Petrof Bay retired to Ulithi, stopping at Guam in the Marianas Islands along the way. At Guam, Composite Squadron (VC) 76 was disembarked and replaced with Composite Squadron (VC) 93 on 10 March.[12][32]

At Ulithi, Petrof Bay was assigned to Task Unit 52.1.2, under the command of Rear Admiral Felix Stump,[10] in preparation for the Battle of Okinawa. She departed on 21 March, escorting Task Group 54.1 en route. Upon arriving, on March 26, Petrof Bay covered the Marines that landed on the Kerama Islands as a preliminary for the main battle. On March 31, she also provided support for the Marines landing on Keise Shima, a small archipelago of islets 8 mi (13 km) to the west of Naha. On 1 April, the main landings on Okinawa took place, and aircraft from Petrof Bay provided close air support every step of the way.[12]

On 13 April, Petrof Bay was ordered to neutralize Japanese airfields in the Sakishima Islands, from which kamikazes were operating. The first strikes were launched from a distance of 228 mi (367 km) away, and her aircraft engaged heavy anti-aircraft fire upon arrival, which shot down two fighters, including VC-93's commander, albeit the crew of both aircraft were quickly rescued. By 16 April, Petrof Bay had resumed her typical operations over Okinawa.[12][33]

Petrof Bay continued air operations, with occasional breaks for refueling, rearming, and resupply until 26 May, when she was relieved of her duty by the arrival of other escort carriers. VC-93 had shot down seventeen enemy aircraft, had a probable kill on another, and destroyed many other planes on the ground, but it had lost four Wildcats due to combat, six Wildcats operationally, and it had also lost four Avengers operationally. To alleviate the pressure on the fighter pilots, six of the Avenger pilots had volunteered to become fighter pilots, with one of these "hybrid" pilots becoming VC-93's top scorer, shooting down four aircraft. Petrof Bay had lost the lives of two pilots and one crewman in the course of the operation.[12][34]

Upon being relieved, Petrof Bay headed for Guam, entering Apra Harbor on 30 May. There, Composite Squadron (VC) 93 was disembarked, and Composite Squadron (VC) 90 was taken onboard, albeit for transportation to Pearl Harbor. On 19 June, she arrived at Naval Air Base San Pedro, on Terminal Island, for a general overhaul. She completed her overhaul on 13 August, and sailed for Pearl Harbor. En route, on 15 August, news of the Surrender of Japan reached the crew.[12]
