- The ship's Lingayen Gulf action report (downloaded and OCR-read this session; key page also verified by direct image display) documents: underway from Manus Island 27 December 1944 under COMDESRON 49 Secret Movement Plan No. 1-44 for the Lingayen assault, S-Day 9 January 1945; repeated convoy air attacks by Val-type aircraft (one crash-dived a CVE on S-2 evening); on S-Day the ship opened fire at 4000 yards with 5-20MM and 3-40MM; beached and unloaded S+1; on S+3 morning (12 January) suffered a near miss 25 yards off the starboard bow at 0634, wounding one Gunners Mate of No. 1 40MM in the arm and damaging compartments A-303-M, A-404-V, and A-402-V (bomb judged 100-lb anti-personnel type); departed with a Leyte Gulf-bound convoy on the evening of S+3. Ammunition expended: 639 rounds 20MM, 281 rounds 40MM. The report's final page records verbatim: 'Enroute from Manus Island, Admirality [sic] Islands the Captain, D. P. SPENCER, Lieut. USNR died on 31 December 1945 [sic] and was buried at sea on 31 December 1944 at Long. 137 deg 57 min E lat, 03 deg 58 min N. The Executive Officer assumed command.' - the printed death-year '1945' is an internal typo contradicted by the same sentence's burial date and the NavSource CO table (Hearne commanding from December 1944).

The 3rd Amphibious Corps, U.S. Army' (the report's own wording), 533 troops; cargo of vehicles, DUKWs, 105MM artillery pieces with 7,000 rounds, 660 tons, plus 40 tons of hydrographic equipment (buoys, concrete clumps, chain); cargo loaded at Guadalcanal and hydrographic gear at Tulagi 5-6 March 1945. Troops disembarked at the objective on LOVE day (1 April) and LOVE+2; cargo unloaded LOVE, LOVE+1, LOVE+2, and LOVE+8. The ship accounted for two enemy planes on LOVE+5 (6 April) - one at approximately 1600 by the forward 40MM gun, one at approximately 1700 by 40MM/20MM fire - during mass air attacks on shipping at the objective area; both planes observed to crash into the sea; 'suicidal tendencies were shown by enemy pilots.' No damage and no ordnance derangement; ammunition expended 249 rounds 40MM and 505 rounds 20MM. The endorsement chain (ComLSTGrp 42, 6 May, noting detachment from Task Unit 53.3.3 on 5 April 1945; LST Flotilla EIGHT, 4 June; LST Flotilla THREE, A. A. Ageton, 16 June; ComLSTFlot SIX / CTG 53.3, J. S. Laidlaw; ComPhibGrp FOUR / CTG 53; ComPhibsPac / CTF 51) documents the operational routing for the Okinawa assault.

S. W. Hearne, USNR (matching the NavSource unit table and the action-report endorsement chain's CTG 53.3 = ComLSTFlot SIX); and photo NH 79015-A documents the ship in San Francisco Bay in 1945-46, consistent with the post-occupation return and 14 May 1946 decommissioning.

Asbestos-relevant applications aboard a 1944 diesel landing ship of this type were the era-standard set - diesel-exhaust and machinery-space lagging, gaskets and packing, accommodation thermal insulation, and deck coverings.
