I knew about operations in The Sudan because about 25 years ago when I was running a shop selling militaria I met an old chap who told me that he had served there in the 1st World War as an officer with a Sudanese Camel Corps unit. He won the Military Cross there for some action or another, making him one of the few officers ever to have won the MC on a camel, I'm guessing! At the time I happened to know another gentleman who had also won the MC (more conventionally in France) and both of them agreed to bring their medals in for me to photograph. Sad to think that all these people are now long gone.
