With Buller in Natal by G. A. Henty

Historical novel set in South Africa in the late 19th century, during the Zulu War. The Preface begins: It will be a long time before the story of the late war can be written fully and impartially. Even among the narratives of those who witnessed the engagements there are many differences and discrepancies, as is necessarily the case when the men who write are in different parts of the field. Until, then, the very meagre military despatches are supplemented by much fuller details, anything like an accurate history of the war would be impossible. I have, however, endeavoured to reconcile the various narratives of the fighting in Natal, and to make the account of the military occurrences as clear as possible. Fortunately this is not a history, but a story, to which the war forms the background, and, as is necessary in such a case, it is the heroes of my tale, the little band of lads from Johannesburg, rather than the leaders of the British troops, who are the most conspicuous characters in the narrative. 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).
