Jim’s Quote of the Day:

“The larger [Persian] Ismaili fortresses provide outstanding examples of military architecture. Their strategic position and the skilled use of natural resources to ensure, that despite the difficulties of the terrain, the castles were well supplied with food and water and therefore able to withstand a prolonged siege of many months, even years. In his account of the destruction of Alamut by the Mongols, the historian Juwayni (d. 1283) describes with considerable admiration the vast underground store rooms built by the Ismailis and the difficulty the Mongols had to destroy the castle’s fortifications.”
