Arrived before the city, he found that there was an army opposed to him there, under the command of a general named Antigonus. His army was encamped upon a hill near the city, awaiting his arrival. The mind of Pyrrhus had become so chafed and irritated by the opposition which he had encountered, and the defeats, disappointments, and mortifications which he had endured, that he was full of rage and fury, and seemed to manifest the temper of a wild beast rather than that of a man. He sent a herald to the camp of Antigonus, angrily defying him, and challenging him to come down from his encampment and meet him in single combat on the plain. Antigonus very coolly replied that _time_ was a weapon which he employed in his contests as well as the sword, and that he was not yet ready for a battle; adding, that if Pyrrhus was weary of his life, and very impatient to end it, there were plenty of modes by which he could accomplish his desire. Pyrrhus remained for some days before the walls of Argos, during which time various negotiations took place between the people of the city and the several parties involved in the quarrel, with a view to an amicable adjustment of the dispute, in order to save the city from the terrors attendant upon a contest for the possession of it between such mighty armies. At length some sort of settlement was made, and both armies agreed to retire. Pyrrhus, however, had no intention of keeping his agreement. Having thrown the people of the city somewhat off their guard by his promise, he took occasion to advance stealthily to one of the gates at dead of night, and there, the gate being opened to him by a confederate within the city, he began to march his soldiers in. The troops were ordered to keep silence, and to step noiselessly, and thus a large body of Gauls gained admission, and posted themselves in the market-place without alarming or awakening the inhabitants. To render this story credible, we must suppose that the sentinels and guards had been previously gained over to Pyrrhus's side.
