I was actually talking to my mum about this the other day. She volunteers at a local National Trust property and spends a day a week in tbe local archive going through the papers from the house. A few weeks ago they found a letter from a family member who was serving a the time and he mentions the death of the Prince Imperial. Apparently the was quite scathing about the troops who had been charged with protecting him, which I gather was a common sentiment at the time.
