With a presence of mind, which in some measure justifies his foolhardiness, Caesar hastily collected his scattered men; seized the persons of the king and his ministers; entrenched himself in the royal residence and adjoining theatre; and gave orders, as there was no time to place in safety the war-fleet stationed in the principal harbour immediately in front of the theatre, that it should be set on fire and that Pharos, the island with the light-tower commanding the harbour, should be occupied by means of boats. Thus at least a restricted position for defence was secured, and the way was kept open to procure supplies and reinforcements. At the same time orders were issued to the commandant of Asia Minor as well as to the nearest subject countries, the Syrians and the Nabataeans, the Cretans and the Rhodians, to send men and ships in all haste to Egypt. The insurrection, at the head of which the Princess Arsinoe and her confidant, the eunuch Ganymedes, had placed themselves, meanwhile had free course in all Egypt and in the greater part of the capital. In the streets of the latter there was daily fighting, but without success either on the part of Caesar in gaining freer scope and breaking through to the fresh water lake of Mariut which lay behind the town, where he could have provided himself with water and forage; or on the part of the Alexandrians in acquiring superiority in besieging and depriving them of all drinking water; for, when the Nile canals in Caesar's part of the town had been spoiled by the introduction of salt water, drinkable water was unexpectedly found in wells dug on the beach.
