'BIGOT—TOP SECRET—Gunfire-support overlay, with Annex Able Intelligence Plan—Appendix 1 to Annex Dog; Annex Able sheets 1–19'


This is an original BIGOT–Top Secret naval bombardment overlay for Utah Beach, issued to Assault Force U before D-Day, 6 June 1944, with nineteen sheets of the force's Intelligence Plan. Laid over a 1:50,000 map, it fixes the firing stations of the Pearl Harbor veteran Nevada, the cruisers Tuscaloosa, Quincy and Black Prince and their destroyers, to be taken before H-40, forty minutes before the first troops landed; among them is USS Corry, sunk that morning. BIGOT was the invasion's highest level of secrecy, reserved for those who needed to know where and when it would strike. The Intelligence Plan, Serial 00010, also BIGOT and dated 15 May 1944, briefs the force on the Utah beaches, obstacles and German defences; sheet 20 is absent. Both were retained by Lieutenant Carl M. Good Jr, whose subchaser SC-1301 spent D-Day shepherding landing craft between the troopships and Utah Beach, and stayed in his family for over eighty years. Provenance is supported by a certified letter and set out in the linked dossier, with copies of the Navy records naming Good in command, his handwritten account and a crewman's eyewitness recollection. The overlay has been repaired, with some losses; the base map is not present.

BIGOT–TOP SECRET. Appendix 1 to Annex Dog (Gunfire Support Plan), Assault Force U / CTF 125 Operation Order No. 3-44: 'Overlay to 1/50000 map/chart furnished (all targets will be plotted accurately by coordinates on map/chart). Positions shown are those to be occupied prior to H-40.' The overlay does not name its parent order on its face; its annex numbering, content and provenance place it with Force U's Operation Order No. 3-44. [England]: Assault Force U, Western Naval Task Force, United States Navy, 1944. The parent operation order is dated 15 May 1944; a separate printing date for the overlay has not been established. Original contents: one 1:50,000 gunfire-support overlay, 38 × 29 inches (96.5 × 73.7 cm); and Annex Able, Intelligence Plan, serial 00010, dated 15 May 1944, comprising numbered sheets 1–19 of 20. Sheet 20 is absent. The overlay plots planned bombardment stations, swept channels and a transport area. A printed note states that the fire-support areas and stations were drawn to conform to the minesweeping plan. Two ship names beside Nevada, Tyler and Hotham, are struck through, apparently in pencil. The Intelligence Plan sheets are headed TOP SECRET–BIGOT–NEPTUNE. An overlay is a separate operational layer intended to be read over a base map; the underlying 1:50,000 map or chart is not present. Provenance: Lieutenant Carl M. Good Jr, USNR, commanding officer of USS SC-1301; by descent to his son and then to his grandson, who consigned the material to Centurion Auctions, Tallahassee, Florida, sale of 16 August 2026, lots 149252 and 149254, as stated in Centurion's signed Letters of Provenance of 26 August 2026 (inventory 92245 and 92247), in which the firm's owner, Malcolm Mason, records meeting the consignor in person. Muster forwarding sheets dated 31 March and 30 June 1944 identify Good as commanding officer on dates bracketing D-Day; SC-1301's sailing list of 30 September 1944 and the quarterly-roll forwarding sheet of 31 December 1944 carry his command to the end of 1944, and the 1953 Register of Commissioned and Warrant Officers of the United States Naval Reserve confirms his file number, 102979, and his later rank of lieutenant commander. Gunner's Mate Third Class Tolley Fletcher, who is indexed on SC-1301's 1944 muster rolls, recalled in Military Times (5 June 2019) that the ship escorted landing craft into Utah Beach on D-Day. An unsigned six-page manuscript account of SC-1301's operations from 1 June to 31 August 1944, written in the first person by the ship's commanding officer, records the crossing from Dartmouth with an LCM flotilla in a Force U convoy, landing-craft control from the transport area on 6–8 June, shuttle-control duty off Omaha Beach, and orders of 29 August to join the area screen; it names no beach for D-Day itself. Association of the originals: the overlay came from Centurion lot 149252 (asset/title 4536); the Intelligence Plan came from lot 149254 (asset 4537), within the same family consignment. They have been paired by us for this sale. Annex Able supplies related beach intelligence, not the overlay's own Annex Dog explanatory text. This is a selected group of components, not a complete operation order or an intact wartime file. The Assembly and Staging originals and the other two overlays are offered separately and are not included. Modern supporting material: a provenance portfolio (PDF, September 2026) reproducing the two Centurion Letters of Provenance, whose signed certified originals are embedded in the PDF, the two US Navy muster forwarding sheets, an extract from the 1953 Naval Reserve Register, a summary of Tolley Fletcher's eyewitness recollection, the six-page operational account with a typed transcription, a portrait of Good as an ensign, overview images of this lot's typed papers and extracts from the Assembly and Staging Table. No original manuscript journal or original wartime photographic prints are present.

Condition Guide

We assess the condition of each item using three categories: Good, Fair, and Poor. We strive to ensure that any significant flaws are clearly shown in the images provided and detailed in the accompanying condition statement.

Good

The item presents well, with no significant flaws, and is in frameable condition. Minor imperfections—such as light spotting or offsetting, small blemishes, tight margins, neatly repaired tears, or discreet/professionally executed restoration—do not materially detract from its overall appearance.

Fair

The item shows noticeable flaws but remains in frameable condition. Some buyers may feel these imperfections affect its visual appeal. Typical issues may include more prominent spotting, blemishes, bleed-through from the reverse, obvious offsetting, visible or extensive restoration, wear along fold lines or junctures, small wormholes, trimmed or closely cropped edges, or less carefully executed repairs.

Poor

The item has major flaws that significantly impact its presentation and/or suitability for framing. These may include heavy spotting, staining, bleed-through, offsetting, unrepaired damage, or poorly executed repairs such as tears, holes, or areas of paper loss (including within the printed image). The item may also be fragile and prone to further deterioration.
