The treacherous capture of this youthful chieftain was one of the skilful devices on which Sir John Perrott most prided himself. Although a mere lad, the mysterious language of ancient prophecy, which seemed to point him out for greatness, give him consequence in the eyes of both friends and foes. Through his heroic mother, a daughter of the Lord of the Isles, he would naturally find allies in that warlike race. His precocious prowess and talents began to be noised abroad, and stimulated Perrott to the employment of an elaborate artifice, which, however, proved quite successful. A ship, commanded by one Bermingham, was sent round to Donegal, under pretence of being direct from Spain. She carried some casks of Spanish wine, and had a crew of 50 armed men. This ship dropped anchor off Rathmullen Castle on Lough Swilly, in which neighbourhood the young O'Donnell—then barely fifteen—was staying with his foster-father, McSweeny, and several companions of his own age. The unsuspecting youths were courteously invited on board the pretended Spanish ship, where, while they were being entertained in the cabin, the hatches were fastened down, the cable slipped, the sails spread to the wind, and the vessel put to sea. The threats and promises of the astonished clansmen as they gathered to the shore were answered by the mockery of the crew, who safely delivered their prize in Dublin, to the great delight of the Lord Deputy and his Council. Five weary years of fetters and privation the young captives were doomed to pass in the dungeons of the Castle before they breathed again the air of their native North.
But now every ship that reached the English or Irish ports brought tidings more and more positive of the immense armada which King Philip was preparing to launch from the Tagus against England. The piratical exploits of Hawkins and Drake against the Spanish settlements in America, the barbarous execution of Mary, Queen of Scots, and the open alliance of Elizabeth with the Dutch insurgents, all acted as stimulants to the habitual slowness of the Spanish sovereign. Another event, though of minor importance, added intensity to the national quarrel. Sir William Stanley, whose account of the battle of Glenmalure we lately quoted, went over to Philip with 1,300 English troops, whom he commanded as Governor of Daventer, and was taken into the counsels of the Spanish sovereign. The fleet for the invasion of England was on a scale commensurate with the design. One hundred and thirty-five vessels of war, manned by 8,000 sailors, and carrying 19,000 soldiers, sailed from the Tagus, and after encountering a severe storm off Cape Finesterre, re-assembled at Corunna. The flower of Spanish bravery embarked in this fleet, named somewhat presumptuously "the invincible armada." The sons of Sir James Fitzmaurice, educated at Alcala, Thomas, son of Sir John of Desmond, with several other Irish exiles, laymen, and ecclesiastics, were also on board. The fate of the expedition is well known. A series of disasters befell it on the coasts of France and Belgium, and finally, towards the middle of August, a terrific storm swept the Spaniards northward through the British channel, scattering ships and men helpless and lifeless on the coasts of Scotland, and even as far north as Norway. On the Irish shore nineteen great vessels were sunk or stranded. In Lough Foyle, one galleon, manned by 1,100 men, came ashore, and some of the survivors, it is alleged, were given up by O'Donnell to the Lord Deputy, in the vain hope of obtaining in return the liberation of his son. Sir John O'Doherty in Innishowen, Sir Brian O'Ruarc at Dromahaire, and Hugh O'Neil at Dungannon, hospitably entertained and protected several hundreds who had escaped with their lives. On the iron-bound coast of Connaught, over 2,000 men perished. In Galway harbour, 70 prisoners were taken by the Queen's garrison, and executed on St. Augustine's hill. In the Shannon, the crew of a disabled vessel set her on fire, and escaped to another in the offing. On the coasts of Cork and Kerry nearly one thousand men were lost or cast away. In all, according to a state paper of the time, above 6,000 of the Spaniards were either drowned, killed, or captured, on the north, west, and southern coasts. A more calamitous reverse could not have befallen Spain or Ireland in the era of the Reformation.
