| Roll of Honour
|
| This list is compiled primarily from documents held in the International Brigade Archive in the Marx Memorial Library, London and the International Brigade Archive in the Russian Centre for the Preservation and Study of Recent Historical Documents, Moscow. It also includes details gleaned from the mass of memoir material, both published and unpublished. The list contains a number of amendments from previous lists, such as those published by Bill Rust and Bill Alexander, which were published before the documents in the Moscow archive were made available. |
The list was compiled by Jim Carmody and Richard Baxell.
