USS William D. Porter (DD-579) - Philippines Campaign

Philippines Campaign

Though William D. Porter arrived in the western Pacific too late to participate in the actual invasion at Leyte, combat conditions persisted there after her arrival in San Pedro Bay. Soon after she anchored there, Japanese planes swooped in to attack the ships in the anchorage. The first plane fell to the guns of a nearby destroyer before reaching Porter's effective range. A second intruder appeared, however, and the destroyer's 5 inch guns joined those of the assembled transports in bringing him to a fiery end in mid-air.

For the remainder of the year, William D. Porter escorted ships between Leyte, Hollandia, Manus, Bougainville, and Mindoro. On 21 December, while steaming from Leyte to Mindoro, she encountered enemy air power once again. Two planes made steep glides and dropped several bombs near the convoy. The destroyer opened up with her main battery almost as soon as the enemies appeared but to no avail. Their bombs missed their targets by a wide margin, but the two Japanese aircraft apparently suffered no damage and made good their escape. Not long thereafter, four more airborne intruders attacked. Porter concentrated her fire on the two nearest her, one of which fell to her antiaircraft fire. The second succumbed to the combined efforts of other nearby destroyers, and the remaining two presumably retired to safety. From then until midnight, enemy aircraft shadowed the convoy, but none displayed temerity enough to attack. Before dawn the following morning, she encountered and destroyed a heavily laden, but abandoned, enemy landing barge. After completing her screening mission to Mindoro, Porter returned to San Pedro Bay on 26 December to begin preparations for the invasion of Luzon.

For the Lingayen operation, William D. Porter was assigned to the Lingayen Fire Support Group of Vice Admiral Jesse B. Oldendorf's Bombardment and Fire Support Group (TG 77.2). The destroyer departed San Pedro Bay on 2 January 1945 and joined her unit in Leyte Gulf the following day. The entire group then passed south through the Surigao Strait, thence crossed the Mindanao Sea, rounded the southern tip of Negros, and then proceeded generally north along the western coasts of Negros, Panay, Mindoro, and finally, Luzon.

By the time the unit reached the southwestern coast of Luzon, it came within the effective range of Luzon-based aircraft. Beginning on the morning of 5 January, enemy planes — including kamikazes — brought the force under attack. William D. Porter saw no action during the first stage of those attacks, because the group's combat air patrol (CAP) provided an effective protective blanket. However, the last raid broke through the CAP umbrella at 16:50 and charged to the attack. Porter took three of those planes under fire at about 17:13, but growing darkness precluded evaluation of the results of that engagement. During that raid, cruiser Louisville (CA-28) and escort carrier Manila Bay (CVE-61) suffered extensive damage from kamikaze crashes.

Before dawn on the 6th, the destroyer moved into Lingayen Gulf with her unit to begin pre-invasion bombardment. Throughout the day, enemy planes made sporadic attacks upon the bombarding ships. That evening, William D. Porter began firing on shore batteries guarding the approaches to the landing beaches. At 17:38, her attention was diverted to a lone plane; and her antiaircraft battery brought it down handily. Twenty minutes later, a twin-engine Mitsubishi G4M "Betty" ran afoul of the destroyer's gunners who splashed this one neatly as well. Porter then returned to her primary mission, shore bombardment.

After the landings on 9 January, the destroyer's mission changed to call fire and night harassing fire in support of the troops. Then, from 11 to 18 January, she stood off Lingayen Gulf with TG 77.2 to protect the approaches from incursion by enemy surface forces. On the 18th, she reentered the gulf to resume support duty for forces ashore and to contribute to the anchorage's air and antisubmarine defenses. On 3 February, the warship bombarded abandoned enemy barges to assure that they would not be used against the invasion force or as evacuation vehicles. She then resumed her antisubmarine and air defense role until 15 February, when she departed Lingayen Gulf to escort Lindenwald (LSD-6) and Epping Forest (LSD-4) to Guam.
