Here they slew the gate-keeper and the sentries who were with him. At the same time the ladders were clapped to the wall, and after getting a hundred men over in all haste, Aratus ordered the rest to follow as fast as they could; then he pulled his ladders up after him and marched through the city with his hundred men against the citadel, being already full of joy at his escape from detection and confident of success. A little farther on they encountered a watch of four men with a light; they were not seen by them, being still in the shade of the moon, but saw them coming up in the opposite direction. So they drew back a little for shelter beneath some walls and buildings, and set an ambush for the men. Three of them they killed in their attack, but the fourth, with a sword-wound in his head, took to flight, crying out that the enemy were in the city.
