In March 1599 Essex took the command of the English troops; he was to suppress the rebellion and grant Tyrone his life only on condition of his complete surrender. But instead of carrying out his orders, which were to attack the rebels in their stronghold, Ulster, Essex remained for long inactive, and at last marched into Munster. One of his subordinate officers, Sir Henry Harington, suffered a disgraceful defeat, partly through his own incompetence, partly through the cowardice of his officers and men. He was tried by court-martial in Dublin, and he himself, and every tenth man of his command, were shot. The summer slipped away, and in its course the 16,000 men with whom Essex had come to Ireland were reduced by sickness and desertion to a quarter of their original number. Under these circumstances, Essex again deferred his march upon Ulster, so that the Queen, who was excessively displeased, expressly forbade him to return from Ireland without her permission. When at last, in the beginning of September 1599, he confronted with his shrunken forces Tyrone's unbreathed army, which had taken up a strong position to await the coming of the English, he abandoned his plan of attack, invited Tyrone to a parley, had half an hour's conversation with him on the 6th of September, and concluded a fourteen weeks' armistice, to be renewed every six weeks until the 1st of May. According to his own account, he promised Tyrone that this treaty should not be placed in writing, lest it should fall into the hands of the Spaniards and be used against him. This was certainly not what Elizabeth had expected of the Irish campaign, which had opened with such a flourish of trumpets, and we cannot wonder that her anger was fierce and deep-seated. No sooner had she received the intelligence, than she forbade the conclusion of any treaty whatsoever. Convinced that his enemies now had the entire ear of the Queen, Essex sought safety in once more disobeying Elizabeth's express command. With a train of only six followers, which in the indictment against him afterwards grew into a body of 200 picked men, he crossed to England to attempt his own justification, rode direct to Nonsuch Palace, where Elizabeth then was, forced all the doors, and, travel-stained as he was, threw himself on his knees before the Queen, whom he surprised in her bed-chamber, with her hair undressed, at ten o'clock in the morning of the 28th of September.
