- Special List 44 inventories US Navy deck logs for YMS-83 in two entries: 'YMS-83 8/25/1942 10/20/1944' and 'YMS-83 1/1/1943 10/20/1944 see YMS-82, 1942' - the second entry cross-referencing 1942 material filed under sister ship YMS-82. Combined coverage begins five days before the recorded completion/commissioning date (30 Aug 1942) and ends exactly on the transfer-to-France date (20 Oct 1944), bracketing the hull's entire U.S. Navy career.

- This is an inventory entry, not the logs themselves: it establishes that logbooks exist (NARA custody) but not their contents - stations, operations, personnel, or any aboard conditions are unread here. No digitized deck-log item for this hull was located in the National Archives Catalog this session (the digitized 'YMS-83, 8/25/42-10/20/44' catalog item is the MUSTER ROLLS series, not the deck logs - see ev-02), so the logs remain an archival lead only.

- The ship's quarterly crew muster rolls for 8/25/1942-10/20/1944 are digitized in the National Archives Catalog (Ancestry partnership scan, reel 8193). Page-level verification: the roll opens with the standard 'Muster Roll of the Crew of the U.S.S. ___ for the quarter ending ___' form sequence. These rolls are the crew-population record for the hull's entire U.S. career - the personnel base any crew-level exposure analysis would draw on.

- The ship's own action report (read at page level) documents YMS-83 sweeping ahead of the Salerno assault force (Operation Avalanche): arrived with convoy FSS-2X from Bizerte 8 Sep 1943; at ~0200 on 9 Sep commenced sweeping the entrance channel for the Southern attack force, fourth in port echelon; exploded a first mine in her sweep gear at 0216 (40deg22'30"N 14deg52'15"E), a second at 0223 (40deg21'04"N 14deg53'10"E), and cut a third loose; two more mines exploded in her gear at 1247 and 1251 near 40deg19'50"N 14deg53'E, the last parting her gear (sweep float and pendant lost); she then served as mine-disposal vessel, sinking four floating mines by rifle fire, and guided five LCIs to Red Beach on 10 Sep. The group swept approximately 32 mines by noon 9 Sep and ~44 total; enclosure (A) attributes six mines to this ship (Type reported as large circular contact-horn mines). Magnetic-acoustic sweep of the channel and transport area 11 Sep returned negative results.

The November 1943 diary (read at page level) places the ship under Task Group 81.4.4 (Escort Sweeper Group) of the Eighth Amphibious Force per Operational Plan N-43, based at La Pecherie, Tunisia (moored alongside sister YMS-82 at Pier 23 East), running convoy-escort legs Bizerte-Naples (5-7 Nov) and Naples-Bizerte (8-10 Nov). The Southern France action report cover letter (verified) independently cites CTF 85 Op Plan 3-44 Annex 'Tare' - the Dragoon minesweeping plan - matching the August diary narrative.

- The YMS type was a wood-hulled, diesel-powered inshore minesweeper designed by Henry B. Nevins, Inc. (YMS-1 laid down 4 March 1941 at City Island, NY); 561 were built at 35 yacht yards - 12 East Coast, 19 West Coast, and four in the Great Lakes (Stadium Yacht Basin being one of the Great Lakes yards). YMS-1 through YMS-134 were the two-stack variant, which includes YMS-83. Surviving YMSs still in U.S. naval service were reclassified AMS and named in 1947 - YMS-83, already transferred to France in 1944, was not among them.

- Finding
- A wooden-hulled diesel yard minesweeper built 1941-42 sits inside the Navy's documented asbestos-use era; era-standard applications aboard a small diesel craft of this type were diesel-exhaust lagging, machinery gaskets, valve packing, electrical insulation, and winch/windlass brake linings in confined below-deck spaces. As a diesel vessel she carried no steam plant - the boiler/turbine lagging pathway of steam vessels does not apply, and the wooden hull means no hull-insulation pathway of steel combatants; residual exposure pathways are machinery-space and maintenance-disturbance.
