I'm preparing to build a miniature version of the fortified camp occupied by British and Indian troops outside the walls of Kabul, for a wargame set in the Winter of 1841-42.
I've found contemporary First Afghan War visual reference with regard to various Afghan cities and British troops, but when it comes to specific images of the Kabul Cantonments themselves -- other than a couple of period maps showing the position of the camp in relation to the city of Kabul and its surroundings (the Seah Sung and Beymaroo Heights, the River and Canal, the various roads to various gates in the city walls) I haven't been able to find any visuals related to the cantonments themselves.
I know the camp was 1000 yds by 600 yds, with earthwork walls, a round bastion at each corner, and one gate facing the Kohistan Road, but that's about it.
The thing I'd like to find most is either an image or written description of the cantonment entrance. Considering how long the Anglo-Indian army occupied the position, I would assume the gateway was somewhat substantial, perhaps even incuding an elevated rampart with swinging doors below... or perhaps it was a more simple affair. A lot of time and effort was invested in building the cantonment, but most of it focused on the barracks for the men and more spacious quarters for the officers.
If anyone reading this can point me to a source for even the slighest additional detail with regard to the First Afghan War Kabul Cantonments, be it written or visual, I will be very grateful indeed -- and thank you in avance for taking the time to read this request!
