Dear Diane:
Fawcett did not serve in the Crimean War. I am working on my 3rd book on the cavalry of the Crimea, dealing with the 10th Hussars, 12th Lancers, 1st Dragoon Guards and 6th Dragoon Guards.The United Service Magazine (1855, Part I,p. 311) notes that "Francis George Savage Curtis, Gent." became a Cornet vice "Fawcett, who retires". It is dated 15 December 1854. I have the muster rolls for the regiment in the Crimea, and do not find his name on them. He is not in Tony Margrave's Officers of the Crimean War 1854, 1855, and 1856, which lists 3 men named Fawcett in the Crimea; His name does not appear on the Medal Roll for the 6th DG in the Crimea. I also checked the indexes for Hart's Annual Army List for 1856, 1857, and 1858 and did not find his name there either. I don't know if Hart's includes Militia members in the indexes, but if not and he had higher ranks than Cornet, it may have been in one of the militias.
If you have more about him you would be willing to share, I would like to include it in my 3rd book (if I ever finish it), with attribution, of course.
Cheers
