Sir John William Kaye, History of the War in Afghanistan…
“ Brydon alone escaped to Jellalabad. Wounded, and worn out by famine and fatigue, he had struggled onward, borne by a jaded pony, till the walls of the fort appeared in sight; and a party came out to succour him.So perished the last remnant of a force which had left Caubul numbering 4,500 fighting men and 12,000 camp-followers. The frost and the snow had destroyed more than the jezails and the knives of the Afghans. It was not a human enemy alone with which those miserable men had to contend. It was theirs to war against a climate more perilous in its hostility than the inexorable foe. ”
