I have had a few questions about my model, but think the easiest way to answer them is to point to a very accurate model of the real FWH. The basement model is not intended to be a model of Fort William Henry, but blends elements from Fort William Henry and Fort Duquesne. At our scale, the basement model is "larger" than Fort Duquesne, but "smaller" than FWH. The real FWH (as depicted in the link below) is as small an artillery bastion fort that one can build without injecting serious military and design
flaws. The basement model generates defensive blind spots on the curtain walls and the bunk space is insufficient to man the fort walls. In order to meet the minimum standard and eliminate the design flaws, the basement fort would have to be 10 feet by 10 feet, bastion tip to bastion tip.
Below is a link for TM Terrain, they produced a very accurate model of the Fort William Henry. The barracks, wall lengths, wall orientations, and rampart thickness (30 feet) are very accurate. The resulting parade ground is very tight, definitely not spacious. Bunk space is at such a premium the barracks themselves are not rectangular and attempt to occupy the maximum possible space. Note the location of the barracks stairs leading to the second floor are all external to the barracks, again to maximize bunk space. The single gate to the fort is hidden from attack (on the east wall, the top of the model is not aligned to the north). The curtain wall with the gun embrasures points south. The critical gun embrasures on the west wall are missing in the model (the wrong map was used for that element of the design).
If you get to the Fort William Henry page, the middle 4 pictures open up showing a much broader image. Other commissions shown as well (Alamo, Arnhem, ....). If you go to the home page, you can now purchase a Pegasus Bridge from TM Terrain, check that out.
