than one-half of the number which left Patala. It is not necessary to follow him to Babylon, or to describe the voyage of Nearchus, who, having sailed up the Persian Gulf, united his forces to those of his royal master in the river Pasi-Tigris, near Susa. Enough, however, may be learned from this history to convince us that if such an army could be conducted 2000 years ago from the Hellespont to the Jaxartes and Indus, the march from the southern shores of the Caspian Sea to Cabool would require comparatively but very slight exertion, if those who have the means should have the desire also to accomplish it. I can say little of my own knowledge of the political causes which gave rise to the war, as I am unacquainted with the affairs of India and the motives which actuated its governors; but a brief outline may be collected from a book lately published by the Hon. Capt. Osborne, military secretary to the Governor-General, to which I shall refer, after making some observations upon the countries through which the operations of the army were conducted, and particularly on the situation of Afghanistan, in reference to those persons who had before been, is well as those who were, its rulers, when Shah Shooja was restored by the British Government to its throne. These observations I have chiefly collected from the valuable work of that enterprising officer Lieut. Burnes, which he published after visiting those countries in 1831, 1832, and 1833. The chief portion of the Bombay division of the army engaged in the operations to which these letters refer, landed at the Hujamree mouth of the Indus, and marching through Lower Sinde, by Tatta, ascended the Indus by its western bank. On arriving in Upper Sinde, it was found that Shah Shooja with his contingent, as well as the Bengal division of the army, had crossed the Indus _en route_ from that Presidency, and had advanced towards Afghanistan, and that the Bombay division was to follow them. To effect this, the division marched through Cutch Gundava, and the Bolan Pass, which is situated in the mountains which divide the province of Sarawar, in Beloochistan, as well as Cutch Gundava, from Afghanistan. Having made their way through the Bolan Pass, the army entered the Shawl district of Afghanistan, and thence proceeded through the Ghwozhe Pass to Candahar, Ghuzni, and Cabool; at which last-mentioned place Shah Shooja's eldest son joined his father with some troops of Runjet Sing's, which had crossed the Indus from the Punjab, marching by Peshawur and the Kyber Pass. The division of the Bombay troops under General Willshire having remained at Cabool about a month, returned to Ghuzni, and thence in a straight direction to Quettah, leaving Candahar some distance on the right; Capt. Outram, who commanded a body of native horse, preceding the main body of the division for the purpose of capturing the forts, or castles, belonging to those chiefs who had not submitted to Shah Shooja.
