The Prince Imperial of France; Louis Napoleon. Here he wears the uniform of the British Royal Artillery. He would go on to fight for the British in the Zulu War of 1879 where he lost his life. I don’t have a date for this photograph, but it should be 1870’s.
James Langley Dalton (Commissariat and Transport Department) superintended the work of defense at Rorke's Drift and was amongst those receiving the first wave of attack, where he saved the life of a man by killing the Zulu assailant. Although wounded himself, he continued to give the same display of cool courage throughout the action. He was 46 at the time of the defence.
