The fortress is a mid-1800s installation guarding a major river crossing. There are two variants; in version 'A', housing and undergrowth have been permitted to encroach on the glacis. After all, this is an old outdated defensive work which could never withstand an enemy with modern weapons for a moment, so why bother? In version 'B' the field of fire around the fort has been cleared except where the town prohibits. This is entirely due to the fact that the commander distrusts the fascists utterly, and nothing to do with the gifts of butter, milk, and meat sent to him by the collective farm whose cattle graze on the cleared area. :)
