"Frontier and Overseas Expeditions" Volume II has a topographical sketch of the village made in 1908 but it isn't very much use from a gaming point of view. About 5 years ago I scoured various other maps and looked at satellite photos on Google maps and made a sketch map.
There is a cultivated area, which played no part in the battle, to the west of the village then a sharp escarpment, running north-south, rising up to the village itself (you could make this escarpment the western edge of the game table). The village of Maizar consisted of about half a dozen walled compounds, with towers, arranged in a rough horseshoe shape, the open end of which faces the escarpment. The middle of the horseshoe is the square where the Anglo-Indian forces halted and is dotted with a few trees. Running east-west through the middle of the village & square is a dirt track.
As you head east you enter a wide open plain, every couple of miles there's a low ridge running north-south. A wider road runs east-west through the plain and then turns north before Maizar itself (the dirt track connects to this road).
I hope that makes some sense!
