In 1413, the mayor and bailiffs, in prosecution of their feud with the Irish sept of O'Driscoll, embarked with an armed force in one of the ships belonging to the city, and sailed to the chieftain's strong castle of Baltimore, on the coast of Cork, where they arrived on the night of Christmas-day. The mayor landed his men, and, marching up to the castle gate, desired the porter to tell his lord that the mayor of Waterford was arrived in the haven with a vessel laden with wine, and would gladly come in to see him; upon the delivery of this message, the gate was opened, and the whole party instantly rushing in, O'Driscoll and all his family were made prisoners. In 1447, the city and the county were granted to John Talbot, Earl of Shrewsbury, created Earl of Waterford, with palatine authority; and in the same year it was enacted by statute of the 25th of Henry VI., that it should be lawful for the mayor and citizens of Waterford, to assemble what forces they pleased, and to ride in warlike array, with banners dis-played, against the Powers, Walshes, Grants, and Dal-tons, who had for a long time been traitors and rebels, and continually preyed upon the king's subjects of Waterford and parts adjacent. In 1460, O'Driscoll persevering in hostilities, all communication between his country and this or any of the English ports was rigidly prohibited by act of parliament. This chieftain, on the invitation of the Powers, whose hostility also continued without intermission, brought his forces by sea to Tramore, on the first intelligence of which the mayor and citizens marched out in battle array to Bal-lymacdane, where they met with the enemy and gave them a signal defeat; 160 of the number were killed, and several taken prisoners, among whom were O'Dris-coll-Oge and six of his sons, who with three of his galleys were brought in triumph to Waterford. Edward IV. was the last sovereign that coined money here; in the 15th of his reign, all the mints of Ireland were abolished, except those of Waterford, Dublin, and Drogheda. In 1484, a shipment by some merchants of Waterford to Sluys, in Flanders, in preference to Calais, raised the important question of Ireland's being bound by statutes made in England, which was finally decided in the affirmative.
