The Bravest of the Brave by G. A. Henty

Classic historical novel. There are few great leaders whose lives and actions have so completely fallen into oblivion as those of the Earl of Peterborough. His career as a general was a brief one, extending only over little more than a year, and yet in that time he showed a genius for warfare which has never been surpassed, and performed feats of daring worthy of taking their place among those of the leaders of chivalry. According to Wikipedia: George Alfred Henty (8 December 1832 - 16 November 1902), referred to as G. A. Henty, was a prolific English novelist, special correspondent, and Imperialist born in Trumpington, Cambridgeshire, England. He is best known for his historical adventure stories that were popular in the late 19th century. His works include Out on the Pampas (1871), The Young Buglers (1880), With Clive in India (1884) and Wulf the Saxon (1895).
