On the same day, the 37th native infantry, three companies of the Shah's sappers under Captain Walsh, and three guns of the mountain train under Lieutenant Green, retraced their steps towards Cabul, where the sappers, pushing on, arrived unopposed; but the rest of the detachment was attacked on the 2d November--on the afternoon of which day, Major Griffiths, who commanded it, received orders to force his way to Cabul, where the insurrection had that morning broken out. His march through the pass, and from Bootkhak to Cabul, was one continued conflict; but the gallantry of his troops, and the excellence of his own dispositions, enabled him to carry the whole of his wounded and baggage safe to the cantonments at Cabul, where he arrived about three o'clock on the morning of the 3d November, followed almost to the gates by about 3000 Giljyes. The causes of the insurrection in the capital are not yet fully ascertained, or, if ascertained, they have not been made public. Lieutenant Eyre does not attempt to account for it; but he gives us the following memorandum of Sir W. Macnaghten's, found, we presume, amongst his papers after his death:-- "The immediate cause of the outbreak in the capital was a seditious letter addressed by Abdoollah Khan to several chiefs of influence at Cabul, stating that it was the design of the Envoy to seize and send them all to London! The principal rebels met on the previous night, and, relying on the inflammable feelings of the people of Cabul, they pretended that the King had issued an order to put all infidels to death; having previously forged an order from him for our destruction, by the common process of washing out the contents of a genuine paper, with the exception of the seal, and substituting their own wicked inventions."
