'BIGOT—TOP SECRET—NEPTUNE—Inner Screening Overlay to Admiralty Chart 2073, wth Admiralty Chart 2073—Appendix I to Annex Charlie'


This is an original Top Secret–BIGOT–Neptune inner screening overlay for Utah Beach: the plan for guarding the invasion fleet at anchor off the beach. Issued to Assault Force U before D-Day and drawn to lie over Admiralty Chart 2073, it lays out anchorages U1 to U7 on a lettered and numbered grid, with the fire-support area, landing-craft ferry-control areas and the Gooseberry blockship breakwater, bounded by screening lines wittily named the Mason Line and the Dixie Line. BIGOT was the invasion's highest level of secrecy, reserved for those who needed to know where and when it would strike. The overlay was kept by Lieutenant Carl M. Good Jr, whose subchaser SC-1301 spent D-Day shepherding landing craft between the troopships and Utah Beach; his account ends with the ship ordered to join the area screen. It 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 accompanying 1919-edition underlying Admiralty chart was acquired separately. The overlay is toned and folded, with ragged loss along its left edge.

TOP SECRET–BIGOT–NEPTUNE (printed as 'Top-Secret Bigot-Neptune'). Inner Screening Overlay, Appendix I to Annex Charlie, Assault Force U / CTF 125 Operation Order No. 3-44, designed for Admiralty Chart 2073. [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 Good-family contents: one Inner Screening Overlay, showing Force U's anchorages U1–U7, fire-support area No. 1, the 'XA' and 'XB' ferry-control areas, the 'C' Gooseberry breakwater and the screening lines named the Mason Line and the Dixie Line. No original operational paper section accompanies this offer: neither the Intelligence Plan nor the Assembly and Staging papers is included in the original. Separately acquired period chart: Admiralty Chart 2073, France – North Coast, Cape Barfleur to Courseulles, compiled from the French Government Charts 1836–1910, with an inset of Port Barfleur from French Government Charts to 1908, included to make the overlay's maritime geography intelligible. London: Admiralty, 10 December 1894 (Captain W. J. L. Wharton, Hydrographer); New Editions 20 September 1911, 16 October 1912 and 11 April 1919; small corrections 1919–1921, the last dated 24 August 1921; engraved by Davies & Company; sold by J. D. Potter, 145 Minories. Purple 'INCREASE 50%' price stamp. This pre-Second World War chart was acquired separately, was not Good's, and remains a separate physical object. Its first-publication and edition dates must not be confused with the date of the 1944 overlay. The dimensions above refer to the overlay, not the chart. 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. This supports the personal and operational association; it does not independently prove use of this particular sheet on 6 June 1944 or authorship of its annotations. Association and scope: the overlay came from Centurion lot 149254 (asset/title 4537) and has been separated from the former two-overlay retail grouping. The chart pairing was assembled by us; it is not an intact wartime pair. The other overlays and original paper sections are offered separately and are not included. Modern supporting material: a provenance portfolio (PDF, September 2026) reproducing Centurion's Letter of Provenance for lot 149254, whose signed original is 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 and an extract from the Assembly and Staging Table, whose original is offered separately. No original manuscript journal or original wartime photographic prints are included.

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.
