Sir Henry Sidney, in writing to his court, had always reported John O'Neil as "the only strong man in Ireland." Before his rout at Lough Swilly, he could commonly call into the field 4,000 foot and 1,000 horse; and his two years' revolt cost Elizabeth, in money, about 150,000 pounds sterling "over and above the cess laid on the country"--besides "3,500 of her Majesty's soldiers" slain in battle. The removal of such a leader in the very prime of life was therefore a cause of much congratulation to Sidney and his royal mistress, and as no other "strong man" was likely soon to arise, the Deputy now turned with renewed ardour to the task of establishing the Queen's supremacy, in things spiritual as well as temporal.
