Towards the latter end of August 1838, rumours reached Bombay and the various military stations in the Deccan, that the troops were about to be called into active service, and that the scene of operations was to be at a distance from our Indian territories. The extensive preparations soon after set on foot, and the unusual activity observable in the various arsenals of the Presidency, left no doubt as to the truth of these reports, and the only subject of speculation that remained was, the precise destination of the forces. Public curiosity was at length set at rest, by the arrival of a proclamation from the Governor General, directing the assemblage of an army for service across the Indus, and explaining at length the intentions of Government. It will not be necessary for the purposes of this narrative that I should canvass the merits of this remarkable document, or enter upon a discussion of the policy on which it was founded. Sufficient is it for me to say that the objects which it professed, were the protection of our commerce, and the safety of our Indian frontiers, both of which were menaced by the intrigues and aggressions of Persia. Having detailed the steps taken by Dost Mahommed in furtherance of the views of that power, and expressed its conviction, that as long as Cabul remained under his government there was no hope that the interests of our Indian empire would be preserved inviolate, the proclamation proceeded to state, that pressing necessity, as well as every consideration of policy and justice, justified us in replacing on the throne of Afghanistan, Shah Sooja-ool-Moolk, a monarch who, when in power, had cordially acceded to the measures of joint resistance to external aggression which were at that time judged necessary by the British government; and who on his empire being usurped by its present rulers had found an honorable asylum in the British dominions. Such in a few words were the objects set forth in Lord Auckland's proclamation and never has unfortunate state paper been assailed with such hostility and bitterness. Whether the censures with which it has been visited are deserved or not I will leave to others to decide, contenting myself with the observation, that failure and success are but too apt to sway men's judgments and to give a character to the circumstances that have led to them. The Bombay troops ordered to form part of the army of the Indus consisted of her Majesty's 2nd, or Queen's Royals, the 17th regiment of Foot, 307 of her Majesty's 4th Light Dragoons, the 1st regiment of Bombay Light Cavalry, two troops of the Honorable Company's Horse Artillery, one company of Foot Artillery, the 19th regiment of Native Infantry, the Poona Irregular Horse, with the Sappers and Miners, the whole constituting an effective force of about 6,000 men, under the command of Lieutenant-General Sir John Keane.
