After a short halt, the THIRTEENTH resumed their march in the beginning of January, 1839, and after passing the boundary of Bhawul Khan, they entered the territory of the Khyrpore Ameer, where the inhabitants evinced a disposition bordering on hostility, and withheld aid of every kind. Towards the end of January they arrived at Roree, and beheld the river Indus, which they were about to pass, upwards of half a mile broad, with its banks clothed with groves of date trees covering hills, which presented a striking contrast to the plains near them, green with corn and tamarisk bushes. After some delay, the fortress of Bakkur was delivered up to the British, as a place of arms during the war in Affghanistan. The troops from Bombay having met with some interruption in their advance through Lower Scinde, part of the Bengal force, including the THIRTEENTH, quitted the Indus, to menace the city of Hyderabad; but returned to Roree in the middle of February, in consequence of the submission of the rulers of Lower Scinde. A bridge of boats had, in the meantime, been placed across the great river Indus, and the THIRTEENTH Light Infantry crossed this celebrated stream, to traverse regions which a British army had never before penetrated, but which are interesting from their association with ancient history, being the scene of the operations, and reverses of Alexander the Great, upwards of two thousand years since: after a march of four days they arrived at Shikarpore, when the difficulties of the enterprise began to assume a formidable character. Advancing from Shikarpore the regiment proceeded through a desert country to Usted, and afterwards continued its route through the arid plains of Beloochistan, occasionally suffering inconvenience from the want of water, and from the predatory habits of the Beloochees, and arrived in the middle of March, at Dadur, situated a few miles from the Bolan Pass.
