"According to the descriptions which I have heard, the fortress erected by Mulla Husayn soon became a very strong building. Its walls made of large stones reached a height of ten meters. On this base, they raised a construction made of enormous tree trunks in the middle of which they arranged a number of loopholes; they then surrounded it entirely with a deep ditch. In fact it was a kind of great tower having stones for the foundation while the higher stories were of wood and provided with three rows of loopholes where they could place as many tufang-chis as they wished, or rather, as they had. They made openings for many doors and postern gates in order to facilitate entrance and exit. "They dug wells, thus securing an abundance of water; underground passages were excavated in order to provide refuge in case of need; storehouses were built and filled with all sorts of provisions either bought, or perhaps taken in the neighboring villages. Finally, they manned the fortress with the most energetic Babis, the most devoted, and the most dependable available among them."
