The Imperial War Museum holds in its collections a short film showing the South African Military Hospital in Richmond Park, which I’ve drawn to the attention of the Museum of Richmond in the hope they will be able to project it at their forthcoming WW1 exhibition, perhaps running it in a loop. It’s a gem.
Both the links listed below are active and were successfully accessed again today 22/7/2014. The IWM link gets you there without any ‘messing about’ but I hope you’ll allow me also to plug the Europeana link, because I think it’s a brilliant website, and a great help to understanding the war in the context of the wider European experience. I hope you’ll find time to explore it.
Imperial War Museum, ‘With the South African Forces’, Reel 3,
Note: The filming of the S.A. Military Hospital in Richmond Park is in Reel 3 and starts at about 1 min 27 seconds into that reel. It runs to the end of that reel. There’s apparently also something at the beginning of Reel 4.
