E. Olson, Lt., USNR, to Commander in Chief, U.S. Fleet via the TG/CTF/Fifth Fleet chain). The report records: lighterage duty for TransRon 13 at Bito Beach, Leyte (five loads, ~750 tons, 2-10 March 1945); combat load taken 12 March (three T-6 flotation tanks, one 2.5-ton truck, one half-track, one armored reconnaissance vehicle, 28 Army enlisted and 3 Army officers); rehearsal with TU 55.3.1 (15-19 March); availability alongside AD-14 for bow-ramp reinforcing cables (21-23 March); underway 25 March in TU 51.14.1 under ComPhibForPac OpPlan A1-45; on Love Day (1 April) LSM-9 was one of six T-6-tank LSMs (9, 11, 135, 136, 31, 57) forming the seventh wave off Hagushi beaches, launched her three tanks from ~150 yards off the reef, beached on the coral reef at 1623 to discharge vehicles, retracted 1735; assisted in downing a 'Zeke' at 0618 with her 40mm; observed the kamikaze crash into APA 92 ~1,000 yards off at 1920; 2-9 April vehicle and ammunition ferrying including reef-beached ammunition unloading; ordnance expended 55 rounds 40mm and 60 rounds 20mm; no personnel casualties; only material deficiency reported was bow-ramp cable shackle failure.

    DOCUMENTED CONFLICT, carried unresolved: the ship's own Report of Changes (NARA NAID 126511865, stamped received 13 October 1945) records LSM-9 sailing from Pearl Harbor to San Diego on 21 September 1945, and a NavSource photo caption independently shows her homeward-bound from Hawaii that day - the hull was at sea between Pearl Harbor and San Diego, not at Okinawa, on 9 October 1945. The Appendix III 'LSM 9 - Grounded' line is therefore treated as a probable clerical error in the compiled casualty list (or a reference to another hull), not as proof of her presence; the claim is recorded here so the conflict is visible rather than silently dropped.

Footnote 4 of the table assigns Fairbanks Morse engines (OCR text layer reads 'Model 38D846 x 10') to hull block LSM 1-145, 201-232, 253-267 - an enumeration that includes LSM-9; other LSM hull blocks ran GM 16-278A diesels per the same footnote. The OCR'd FM model string is garbled and not reconciled with NavSource's '38D81/8X10' (38D8-1/8 x 10); both renderings are reported rather than a single designation asserted.
