Upon landing, Cromwell proceeded to take the other port cities on Ireland's east coast, to facilitate the efficient landing of supplies and reinforcements from England. The first town to fall was Drogheda, about 50 km north of Dublin. Drogheda was garrisoned by a regiment of 3,000 English Royalist and Irish Confederate soldiers, commanded by Arthur Aston. After a week-long siege, Cromwell's forces breached the walls protecting the town. Aston refused Cromwell's request that he surrender. In the ensuing battle for the town, Cromwell ordered that no quarter be given, and the majority of the garrison and Catholic priests were killed. Many civilians also died in the sack. Aston was beaten to death by the Roundheads with his own wooden leg.
