On the Irrawaddy by G. A. Henty

Historical novel, set during British colonial war in the 19th century. According to the Preface: With the exception of the terrible retreat from Afghanistan, none of Englands many little wars have been so fatal--in proportion to the number of those engaged--as our first expedition to Burma. It was undertaken without any due comprehension of the difficulties to be encountered, from the effects of climate and the deficiency of transport; the power, and still more the obstinacy and arrogance of the court of Ava were altogether underrated; and it was considered that our possession of her ports would assuredly bring the enemy, who had wantonly forced the struggle upon us, to submission. 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).
