I am a transplanted Brit now living in Northern California. I just finished reading your book WATERLOO; The History of Four Days, Three Armies and Three Battles and found it most interested. I am descended from the Slades on my mother’s side of the family. I have a sword (cavalry, I believe) engraved with the name Lieut Henry Slade and with the battles of the Peninsular Wars on the other side. I am trying to find out if Henry Slade may have fought under Wellington at Waterloo. Can you point me in a direction that I may use to research this? I also have a document appointing Henry Slade as a Gentleman Cadet signed by the Earl of Chatham in 1806.
