First published in 1840. According to the Introduction: "The circumstance of an English army penetrating into Central Asia, through countries which had not been traversed by European troops since Alexander the Great led his victorious army from the Hellespont to the Jaxartes and Indus, is so strong a feature in our military history, that I have determined, at the suggestion of my friends, to print those letters received from my son which detail any of the events of the campaign. As he was actively engaged with the Bombay division, his narrative may be relied upon so far as he had an opportunity of witnessing its operations; and it being my intention to have only a few copies printed, to give to those friends who may take an interest in his letters, I need not apologize for the familiar manner in which they are written, as they were intended by him only for his own family, without an idea of their being printed. A history, however, may be collected from them most honourable to the British soldiers, both Europeans and natives of India. They shew the patience with which, for more than twelve months, the soldiers bore all their deprivations and fatiguing marches through countries until then unknown to them, whether moving through arid sands or rocky passes, under a burning sun; or over desolate mountains, amidst the most severe frosts, with scarcely an interval of repose. Neither was their gallantry less conspicuous than their patience, when they had the good fortune to find an enemy who ventured to face them."
