 "Expugnatio Hibernica" relates that they assaulted the walls of the eastern gate, a location that corresponds to St Mary's Gate, the focus of assault identified by "La Geste des Engleis en Yrlande".Unfortunately for Ascall, the operation was an utter failure that resulted in his capture and death.Both sources relate that the town's defenders, led by Cogan and his brother Richard, successfully repulsed the invaders, slew John, and captured Ascall as he fled to his fleet.
