CABAL Crimean Campaign · Last updated: 14 July 2026

CABAL is built on open data and open-source software. This page records the third parties whose work makes the Crimean campaign possible.

Creator

CABAL was created by Nell Watson (github.com/NellInc).

With thanks for instrumental research and engineering assistance from Claude (Anthropic) and Codex (OpenAI), to Filip Alimpić for playtesting and product management, and to the Engineer and Logistic Staff Corps RE (formerly the Engineer and Railway Staff Corps) for inspiration.

Terrain — Copernicus DEM

The battlefield terrain is derived from the Copernicus GLO-30 Global Digital Elevation Model (COP30), cropped to the Sebastopol–Balaklava area (44.44°N–44.82°N, 33.34°E–33.86°E) at native 1 arc-second resolution. Redistribution of the derivative heightmap is permitted under the Copernicus DEM Licence.

The modern DEM reflects post-1855 terrain. Some features (for example the Chornaya reservoir, built after the Crimean War, and minor modern cuts and fills near Sebastopol and Balaklava) are noted rather than corrected.

Original media

The Campaign Briefing film was produced for CABAL by Nell Watson using Fable. Its English captions were authored for the film and are available as an optional track.

The Crimean campaign’s telegraph, cabinet, railway, writing, and clock cues are original procedural sound designs generated for CABAL. They evoke period machinery and working environments; they are compositions rather than archival recordings.

Feature positions

Feature coordinates (bastions, redoubts, camps, and the like) derive from a mix of Wikidata P625 points, Wikipedia infobox coordinates, OSM/Mapcarta, and inference from battle narratives. Each feature’s positional precision is tagged in the source as high (<50 m), medium (~50–200 m), or low (200–500 m inference).

Historical cartography

Historical map layers and traced siege works use resized or cropped derivatives of these collection images:

• Charles Alexandre Fay, Map of port of Balaklava and route to Sevastopol. Wikimedia Commons records the image as public domain and free of known copyright restrictions.
• Eugene James Vaughan and James Wyld, Sevastopol, sketch of the Mamelon and new Russian defences, 1855. Credit: Library of Congress, Geography and Map Division.
• W. & A.K. Johnston, Johnstons’ Plan of the Siege of Sevastopol, 1855. Credit: David Rumsey Map Collection, David Rumsey Map Center, Stanford University Libraries.

These period sheets are interpreted sources. Their imagery is warped onto modern elevation data, and their disagreements are preserved as uncertainty rather than presented as exact survey truth.

Historical portraits

Cabinet likenesses use nineteenth-century photographs and prints. Roger Fenton’s 1855 Crimean portraits of John Fox Burgoyne, William Filder, Lord Raglan, James Yorke Scarlett, and James Simpson are public-domain works sourced through the Library of Congress, the Imperial War Museums, or their Wikimedia Commons records. The interface crops these images for medallion framing.

The portrait of Sir John Hall comes from the Wellcome Collection, licensed under CC BY 4.0. The Richard Airey and Richard Dacres likenesses are public-domain nineteenth-century portraits recorded by Wikimedia Commons and the National Portrait Gallery.
