The king, deeply though he resented the secondary position in which he found himself, could not bring himself to abandon a cause in which he had so much at stake, and which was promising so fairly, and for these reasons accompanied the army.
The Christians boldly pushed their way into the Delta of the Nile, the Egyptian forces retreating as they advanced. Here they found a new enemy before which they were powerless. The sultan broke down the banks of the Nile, flooded the whole intervening tract of country, and completely surrounded the Latin forces with an impassable lake.
