Note 78 — Chapter IV · THE PROGRESS OF ATTACK AND DEFENCE

Pent-houses were sometimes elaborately defended. Thus Joinville describes the large “cats” made by St Louis’ engineers to protect the soldiers who were making a causeway across an arm of the Nile near Mansurah (1249-50). These had towers at either end, with covered guard-houses behind the towers, and were called chats-châteaux.
