A singular illustration of the popular feeling occurred the previous August. The Milesian Irish had cherished the belief ever since the disastrous day of Kinsale, that an O'Donnell from Spain, having on his shoulder a red mark (_ball derg_), would return to free them from the English yoke, in a great battle near Limerick. Accordingly, when a representative of the Spanish O'Donnells actually appeared at Limerick, bearing as we know many of his family have done, even to our day, the unmistakable red mark of the ancient Tyrconnell line, immense numbers of the country people who had held aloof from the Jacobite cause, obeyed the voice of prophecy, and flocked round the Celtic deliverer. From 7,000 to 8,000 recruits were soon at his disposal, and it was not without bitter indignation that the chief, so enthusiastically received, saw regiment after regiment drafted from among his followers, and transferred to other commanders. Bred up a Spanish subject—the third in descent from an Irish prince—it is not to be wondered at that he regarded the _Irish_ cause as all in all, and the interests of King James as entirely secondary. He could hardly consider himself as bound in allegiance to that king; he was in no way indebted to him or his family, and if we learn that when the war grew desperate, but before it was ended, he had entered into a separate treaty for himself and his adherents, with William's generals, we must remember, before we condemn him, that we are speaking of an Hiberno-Spaniard, to whom the house of Stuart was no more sacred than the house of Orange.
The Williamite army rendezvoused at Mullingar towards the end of May, under Generals De Ginkle, Talmash and Mackay. On the 7th of June, they moved in the direction of Athlone, 18,000 strong, "the ranks one blaze of scarlet, and the artillery such as had never before been seen in Ireland." The capture of Ballymore Castle, in West-Meath, detained them ten days; on the 19th, joined by the Duke of Wurtemburg, the Prince of Hesse and the Count of Nassau, with 7,000 foreign mercenaries, the whole sat down before the English town of Athlone, which Saint Ruth, contrary to his Irish advisers, resolved to defend. In twenty-four hours those exposed outworks abandoned by the veteran Grace the previous year, fell, and the bombardment of the Irish town on the opposite or Connaught bank, commenced. For ten days—from the 20th to the 30th of June—that fearful cannonade continued. Storey, the Williamite chaplain, to whom we are indebted for many valuable particulars of this war, states that the besiegers fired above 12,000 cannon shot, 600 shells and many tons of stone, into the place. Fifty tons of powder were burned in the bombardment. The castle, an imposing but lofty and antique structure, windowed as much for a residence as a fortress, tumbled into ruins; the bridge was broken down and impassable; the town a heap of rubbish, where two men could no longer walk abreast. But the Shannon had diminished in volume as the summer advanced, and three Danes employed for that purpose found a ford above the bridge, and at six o'clock on the evening of the last day of June, 2,000 picked men, headed by Gustavus Hamilton's grenadiers, dashed into the ford at the stroke of a bell. At the same instant all the English batteries on the Leinster side opened on the Irish town, wrapping the river in smoke, and distracting the attention of the besiegers. Saint Ruth was, at this critical moment, at his camp two miles off, and D'Usson, the commandant, was also absent from his post. In half an hour the Williamites were masters of the heap of rubbish which had once been Athlone, with a loss of less than fifty men killed and wounded. For this bold and successful movement De Ginkle was created Earl of Athlone, and his chief officers were justly ennobled. Saint Ruth, over-confident, in a strange country, withdrew to Ballinasloe, behind the river Suck, and prepared to risk everything on the hazard of a pitched battle.
