The withdrawal from Kabul was an arduous march, harassed from Gandamak onwards by Afghan tribesmen. Although the march was far better organised than Elphinstone's retreat, large numbers of stragglers were left behind to be rescued by the rearguard or abandoned to die. Part of one division commanded by General McGaskill was ambushed near Ali Masjid at the narrowest point of the Khyber Pass on 3 November and destroyed. Casualties mounted due to snipers and ambushes until the troops were within sight of Jamrud Fort and safety.
