JELALABAD, a town of Afghanistan, in the province of Cabool, situate in the rich plain of Jelalabad. Though advantageously built on the main road from the Punjab to Cabool, it has neither trade nor manufactures. It will, nevertheless, be ever celebrated in history in consequence of the heroic and successful defence made during the winter of 1841 by a handful of British troops, under Sir Robert Sale, against a numerous army of Afghans. The fortifications were destroyed by order of General Pollock, on his final evacuation of Afghanistan in 1842. Lat. 34. 25. Long. 70. 28.
