G. A. Henty 
With Lee in Virginia [EPUB ebook] 

Historical novel, set during the Civil War. The Preface begins: ‘The Great War between the Northern and Southern States of America possesses a peculiar interest for us, not only because it was a struggle between two sections of a people akin to us in race
and language, but because of the heroic courage with which the weaker party, with ill-fed, ill-clad, ill-equipped regiments, for four years sustained the contest with an adversary not only possessed of immense numerical superiority, but having the command of the sea, and being able to draw its arms and munitions of war from all the manufactories of Europe. Authorities still differ as to the rights of the case. The Confederates firmly believed that the States having voluntarily united, retained the right of withdrawing from the Union when they considered it for their advantage to do so.’ 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).’
