The record behind the story

Remember with care.
Research with honesty.

Historical records do not always agree. This project makes its sources and the limits of its reconstruction visible.

Photographs and their provenance

The collection brings together photographs of the ships, people and places connected with their story. The externally sourced images link to their catalogue or original file records and carry their own reuse credits. The project-supplied Limbourne photograph has a separate provenance note below. Modern memorial photographs are not presented as wartime scenes.

The project’s original Limbourne photograph

The black-and-white port-bow photograph was supplied during this project’s earlier model research. Its IWM watermark is preserved and the image is reproduced without retouching. The photographer, exact exposure date, location and original collection reference have not yet been confirmed. This site does not assert a public-domain status or grant a wider reuse licence for that supplied copy.

Where accounts differ

QuestionHow it is presented here
When did Limbourne enter service?October 1942. Commissioning on 23 October and completion on 24 October are recorded as separate milestones.
Which British ships sailed?The Admiralty account’s actual force includes Stevenstone, which replaced Melbreak before departure.
When was Limbourne hit?About 01:52 in the British Battle Summary. Times are reported historical times, not UTC.
How was Limbourne finally sunk?Talybont and Rocket carried out the scuttling after the failed tow. Accounts differ on the weapons and sequence; the Battle Summary gives final sinking at 06:40.
How fast was Limbourne?Published figures vary around 27–29 knots. A precise speed is not used to imply certainty.

Keeping the two ships distinct

Charybdis was the Dido-class cruiser leading Force 28; Limbourne was a Hunt Type III escort destroyer. Charybdis sank after torpedo hits, while Limbourne remained afloat until rescue, attempted towing and scuttling. The Admiralty report’s 107 rescued from Charybdis is not a Limbourne survivor total.

Charybdis casualty figures also differ: Mason’s chronology prints 426 deaths, while the Royal Court’s account gives 464. This site uses “hundreds” in the narrative and links to the named Roll of Honour rather than selecting an unverified total. The memorial brings together separately identified records for both ships, with the evidence shown for each person.

The Guernsey account’s 21 bodies ashore is kept separate from 19 burials reported for 17 November. Likewise, photographs of Jersey graves are not labelled as Guernsey or as images of that funeral.

The places on the map.

The geographic map uses Natural Earth’s public-domain land polygons, clipped to the Channel and northern Brittany. The modern coastline is generalised for this scale. Town and island markers locate the story approximately; they are not cemetery entrances or navigation waypoints.

The shaded sea area locates the fighting north of Sept-Îles in general terms. It does not mark either wreck, establish a battlefield boundary, or trace the ships’ courses. Each place links to the reports and remembrance accounts behind its story.

Reading the action schematic

The timeline’s diagram shows the British line-ahead order and the German outer escort’s reported sailing order. Ship spacing and locations are illustrative. The markers remain in formation order while the selected event changes their status; this is not a continuous or precisely plotted track reconstruction.

The westward British sweep of 267° at 13 knots and the eastbound German escort context come from the reproduced British and German reports. Later manoeuvres are not plotted. The attack band indicates an event, not the path of an individual weapon.

The memorial is still being assembled.

The shared register currently contains 524 entries: 55 connected with Limbourne, 466 with Charybdis and 3 with the rescuing ships. Published casualty rolls, survivor accounts, documents and family evidence are identified within the individual profiles. These are register-entry counts, not independently reconciled ship totals or a final-night muster.

The wider-force register begins with three Wensleydale rescuers. A “Rescue participant” category records their role without making a claim about their later fate. Their profiles distinguish the ship’s published report from later recollections and identifications. Other rescuing ships can be selected even while their person records remain to be established.

Mason’s short history gives 42 deaths and 100 survivors. Another account reports 103 rescued, while later compilations count American personnel and deaths from wounds differently. A reconciled, name-by-name final-night muster has not yet been established. Neither a design complement nor a casualty total can substitute for that work.

The next evidence to seek

A final-night muster or pay record; individual service and casualty records; names attached to dated photographs; and letters that can be connected to known people. Contributions are most useful when they include an archive reference, a date, and how the person was identified.

“Published memorial roll” means the name is transcribed from the linked source; it does not imply that this project has independently verified the individual’s full service history. Spelling, ranks, affiliations and memorial details remain open to correction with evidence.

Reading the interactive 3D scene.

The opening approach follows the reported 00:30 position off Les Héaux, course 267°, speed 13 knots and three-cable spacing. Later movements connect narrative stages schematically. They are not recovered navigational tracks or measured wreck positions.

The scene combines modern terrain with reconstructed ships. Modern coastline, elevation and the light’s reference position do not establish the exact 1943 shoreline, tide, weather or chart datum. The default geographic scale preserves the relationship between hull size and distance; enlarged ships are an examination aid.

Two Limbourne revisions

The separate educational explorer retains Revision 2 and its 21 sections. The full scene uses a viewing derivative of Revision 3, with revised hull proportions. Its underwater form and several fittings still require original plans. A newer revision is not a claim of complete historical verification.

Different levels of evidence

Charybdis has her own detailed model. Grenville, Rocket, the other Hunts and the five German torpedo boats use class studies. Münsterland and her close escort remain identity or count markers where a supported hull has not been reconstructed.

The full-scene viewing files group equivalent materials to reduce rendering work while retaining their source triangles. Small fittings remain available for examination; geographic and historical uncertainty is unchanged by this optimisation.

These six GLB files supply the twelve modelled warships in the scene. Matching materials are grouped for efficient viewing, so they do not preserve every separately editable part in the model masters. Check whether your application imports GLB.

Set the scale before using a file.

Each file is normalised to a hull length of 100 display units. To recover the model’s nominal full size in metres, multiply all dimensions by the factor below. The bow points along −X, +Y is up, and Y = 0 is the nominal waterline. These are viewing derivatives; use the model masters and their fabrication notes when preparing a print.

Nominal dimensions belong to the reconstruction and its cited ship or class references. They do not certify the hull shape, small fittings or final-day outfit.

Limbourne’s 3D reconstruction.

Limbourne’s explorer uses the existing detailed Revision 2 reconstruction, originally made as a 1:200 print model. The browser asset preserves 80 ship meshes and 171,447 triangles, with 21 educational sections. It shows the ship’s major arrangements and helps explain how equipment and people worked together.

Supported by the evidence

Hunt Type III identity; two twin main-gun mountings; torpedo bank; the broad photographic form of the bridge, mast and funnel; and the ship’s principal external arrangement.

Interpreted or provisional

Hull sections and beam; exact equipment stations; windows and portholes; boat types and side assignments; small fittings and final-day aerial detail. Rails and barrels include intentional printing thickening.

Illustrative underwater shape

The lower hull, propellers, shafts and rudder are not verified against ship-specific hull lines. They can be shown for explanation, but are hidden in the default waterline view.

Neutral display colours

These tones help separate surfaces. They are not a reconstruction of Limbourne’s camouflage. No ship-specific paint sheet has been established, and the site does not present colourization as original colour evidence.

This is an educational reconstruction, not a measured digital twin, a certified final-day fit or a model of the wreck. It contains no surveyed interior compartments. The guided tours explain the existing geometry and link related naval roles to memorial entries. They do not establish the watch station of an individual sailor. The next step toward higher accuracy is measurement against the Greenwich drawings and additional dated photographs.

Naval roles and everyday life

The role explorer draws on the June 1942 Navy List’s branch and rank structure and Harold J. Siddall’s firsthand memoir. Its everyday-life and engineering examples are identified as general naval context, not records of Limbourne’s menus, compartment assignments or watch routine.

Limbourne-specific accounts of Cunliffe-Owen taking command, the motor-boat journey and wounded men trapped in the Wireless Office are attributed to the reproduced Battle Summary and ship report. They do not establish the unnamed men’s identities.

Roy Pelling: naval service and survival.

Roy Pelling survived the loss of HMS Limbourne. His family confirms this explicitly, and the Navy Search reconstruction records continued service after 23 October 1943. It identifies official number KX 164423 and Stoker 2nd Class aboard Limbourne from 15 May to 23 October 1943.

Navy Search reconstructed the service history from Payment and Victual ledgers because the original individual service record was not found. The profile preserves the first 19 entries and adds eight continuation rows, reaching the explicit release-to-shore date of 24 October 1946. Missing dates and unclear continuation-page readings remain marked rather than inferred. Shore-establishment entries do not establish every physical movement.

The continuation includes Braganza, Bambara and Formidable. India’s Bombay connection remains provisional for the unsuffixed Braganza entry; Bambara has a documented Ceylon establishment connection. Italy Star entitlement and later Royal Australian Navy service are reported in the family working biography and await independent confirmation. Campaign entitlement alone cannot establish a landing in Italy.

The two restored military photographs were supplied for this update. They are shown at their supplied 1152 × 1536 resolution and labelled as AI-assisted restorations and colourizations. The original identification photograph is retained for comparison. Exact dates and the overseas temple’s location are unconfirmed; the restored board is not used to read Roy’s official number. These photographs carry no wider reuse licence.

Charybdis’s own reconstruction.

Charybdis’s full-hull model represents the intact cruiser before her loss, using ship photographs and wartime recognition material. Her four twin 4.5-inch main mountings, two triple torpedo banks and distinctive bridge and funnels distinguish her from the original five-mount Dido design. The model offers thirteen educational systems, linked to the final-night account and the crew.

Dimensions and visible arrangement

The US Navy’s ONI 201 recognition sheet gives 512 feet overall length and 50.5 feet beam. February 1943 photographs support the major upper works. These references support the overall form; they are not a measured builder’s model.

Below the waterline

Four propeller shafts are represented. Body contours, nominal 5-metre draft, shaft offsets, rudder and bilge keels are reconstructed. A wreck photograph supports three blades on one screw; dimensions, pitch and applying that form to all four remain inferred.

Fine fittings and final fit

Exact October 1943 light-AA and radar details, small equipment positions, boat types and raft stowage remain uncertain. The model notes identify these limits for individual systems. Interior machinery spaces are explained, not reconstructed as surveyed compartments.

A model, not a wartime photograph

The model and its preview are original project geometry and renders. Their display colours are illustrative, not verified camouflage. Reference photographs retain their own rights; the model’s publication does not grant permission to republish them.

The National Maritime Museum’s 1937 Dido-class drawings are important research leads. Their five-mount layout cannot be copied directly into Charybdis. Original drawing images were not available for measuring hull offsets, and catalogue access does not establish republication rights.

Press, video and personal accounts.

The media archive links to original publishers. Summaries identify the ship and distinguish reporting, recollection and documentary sources. Dates are publication dates where verified; an unknown date remains unconfirmed. Personal testimony is identified as recollection and read alongside contemporary records.

News reports sometimes misidentify the attacking craft or repeat inconsistent casualty totals; those details have not been adopted as settled historical facts.
