The field encampment was either a square, or a parallelogram, with a principal entrance in one of the faces; and near the centre were the general’s tent, and those of the principal officers. The general’s tent was sometimes surrounded by a double rampart or fosse, enclosing two distinct areas, the outer one containing three tents, probably of the next in command, or of the officers on the staff; and the guards slept or watched in the open air. Other tents were pitched outside these enclosures; and near the external circuit, a space was set apart for feeding horses and beasts of burden, and another for ranging the chariots and baggage. It was near the general’s tent, and within the same area, that the altars of the gods, or whatever related to religious matters, the standards, and the military chest, were kept; and the sacred emblems were deposited beneath a canopy, with an enclosure similar to that of the general’s tent. In attacking a fortified town, they advanced under cover of the arrows of the bowmen; and either instantly applied the scaling-ladder to the ramparts, or undertook the routine of a regular siege: in which case, having advanced to the walls, they posted themselves under cover of testudos, and shook and dislodged the stones of the parapet with a species of battering-ram, directed and impelled by a body of men expressly chosen for this service: but when the place held out against these attacks, and neither a _coup de main_, the ladder, nor the ram, was found to succeed, they used the testudo for concealing and protecting the sappers, while they mined the place; and certainly, of all people, the Egyptians were the most likely to have recourse to this stratagem of war, from the great practice they had in underground excavations, and in directing shafts through the solid rock.[b] SOCIAL CUSTOMS The subject of manners and customs of the Egyptians has had a peculiar fascination for almost all students of Egyptian history. It is difficult to get away from the feeling that there is something mysterious and occult about Egyptian life, and thousands of people have gazed with mingled admiration and awe upon the monumental remains of this people without caring in the least for the strange-sounding names of the monarchs or for the details of their political history.
