Image Chasseurs d'Afrique in the Crimea - Fenton
Book here. By Hugh Mulleneux Walmsley this book which I haven't read yet looks interesting covering the war in Italy. Having a quick glance it looks very interesting with accounts of Solferino and much more.
Also published in the 1860s was the bestseller Under Two Flags about The Hon. Bertie Cecil's service in the regiment in Africa - a kind of mounted Beau Geste. Read it here
