When I was down in Portishead today Charlie was telling me about a section on the BBC news site called Reality Check and particularly an article called "The fake news about India and China's border clash."
It turns out that he had spent time with both the Indian and Bangladeshi armies while serving with British Forces.
He also told me a story about another part of the world, when he was with a ramshackle Sudanese contingent that accidentally strayed over the border into Eritrea. Vegetation stirred and they were intercepted by deeply camouflaged Eritreans who seemed to appear from nowhere. Luckily for Charlie the officers had been trained and Sandhurst and treated him with exemplary civility. Not so much detailing him as "inviting" him back the their headquarters for the evening.
