Xerxes watched this transaction from his place on the hill with extreme interest and pleasure. He saw the vessel of Artemisia bearing down upon the other, which last he supposed, of course, from Artemisia's attacking it, was a vessel of the enemy. The only subject of doubt was whether the attacking ship was really that of Artemisia. The officers who stood about Xerxes at the time that the transaction occurred assured him that it was. They knew it well by certain peculiarities in its construction. Xerxes then watched the progress of the contest with the most eager interest, and, when he saw the result of it, he praised Artemisia in the highest terms, saying that the men in his fleet behaved like women, while the only woman in it behaved like a man. Thus Artemisia's exploit operated like a double stratagem. Both the Greeks and the Persians were deceived, and she gained an advantage by both the deceptions. She saved her life by leading the Greeks to believe that her galley was their friend, and she gained great glory and renown among the Persians by making them believe that the vessel which she sunk was that of an enemy. Though these and some of the other scenes and incidents which Xerxes witnessed as he looked down upon the battle gave him pleasure, yet the curiosity and interest with which he surveyed the opening of the contest were gradually changed to impatience, vexation, and rage as he saw in its progress that the Greeks were every where gaining the victory. Notwithstanding the discord and animosity which had reigned among the commanders in their councils and debates, the men were united, resolute, and firm when the time arrived for action; and they fought with such desperate courage and activity, and, at the same time, with so much coolness, circumspection, and discipline, that the Persian lines were, before many hours, every where compelled to give way. A striking example of the indomitable and efficient resolution which, on such occasions, always characterized the Greeks, was shown in the conduct of Aristides. The reader will recollect that the Persians, on the night before the battle, had taken possession of the island of Psyttalia--which was near the center of the scene of contest--for the double purpose of enabling themselves to use it as a place of refuge and retreat during the battle, and of preventing their enemies from doing so. Now Aristides had no command. He had been expelled from Athens by the influence of Themistocles and his other enemies. He had come across from AEgina to the fleet at Salamis, alone, to give his countrymen information of the dispositions which the Persians had made for surrounding them. When the battle began, he had been left, it seems, on the shore of Salamis a spectator. There was a small body of troops left there also, as a guard to the shore. In the course of the combat, when Aristides found that the services of this guard were no longer likely to be required where they
