When he joined with Tachos, he found his expectation of being general-in-chief disappointed. Tachos reserved that place for himself, ****** Agesilaus only captain of the mercenaries, and Chabrias, the Athenian, commander of the fleet. This was the first occasion of his discontent, but there followed others; he was compelled daily to submit to the insolence and vanity of this Egyptian, and was at length forced to attend him into Phoenicia, in a condition much below his character and dignity, which he bore and put up with for a time, till he had opportunity of showing his feelings. It was afforded him by Nectanabis, the cousin of Tachos, who commanded a large force under him, and shortly after deserted him, and was proclaimed king by the Egyptians. This man invited Agesilaus to join his party, and the like he did to Chabrias, offering great rewards to both. Tachos, suspecting it, immediately applied himself both to Agesilaus and Chabrias, with great humility beseeching their continuance in his friendship. Chabrias consented to it, and did what he could by persuasion and good words to keep Agesilaus with them. But he gave this short reply, "You, O Chabrias, came hither a volunteer, and may go and stay as you see cause; but I am the servant of Sparta, appointed to head the Egyptians, and therefore I cannot fight against those to whom I was sent as a friend, unless I am commanded to do so by my country." This being said, he despatched messengers to Sparta, who were sufficiently supplied with matter both for dispraise of Tachos and commendation of Nectanabis. The two Egyptians also sent their ambassadors to Lacedaemon, the one to claim continuance of the league already made, the other to make great offers for the breaking of it, and ****** a new one. The Spartans having heard both sides, gave in their public answer, that they referred the whole matter to Agesilaus; but privately wrote to him to act as he should find it best for the profit of the commonwealth. Upon receipt of his orders, he at once changed sides, carrying all the mercenaries with him to Nectanabis, covering, with the plausible pretence of acting for the benefit of his country, a most questionable piece of conduct, which, stripped of that disguise, in real truth was no better than downright treachery. But the Lacedaemonians, who make it their first principle of action to serve their country's interest, know not anything to be just or unjust by any measure but that.
Tachos, being thus deserted by the mercenaries, fled for it; upon which a new king of the Mendesian province was proclaimed his successor, and came against Nectanabis with an army of one hundred thousand men. Nectanabis, in his talk with Agesilaus, professed to despise them as newly raised men, who, though many in number, were of no skill in war being most of them mechanics and tradesmen, never bred to war. To whom Agesilaus answered, that he did not fear their numbers, but did fear their ignorance, which gave no room for employing stratagem against them. Stratagem only avails with men who are alive to suspicion, and, expecting to be assailed, expose themselves by their attempts at defence; but one who has no thought or expectation of anything, gives as little opportunity to the enemy as he who stands stock-still does to a wrestler. The Mendesian was not wanting in solicitations of Agesilaus, insomuch that Nectanabis grew jealous. But when Agesilaus advised to fight the enemy at once, saying it was folly to protract the war and rely on time, in a contest with men who had no experience in fighting battles, but with their great numbers might be able to surround them, and cut off their communications by entrenchments, and anticipate them in many matters of advantage, this altogether confirmed him in his fears and suspicions. He took quite the contrary course, and retreated into a large and strongly fortified town. Agesilaus, finding himself mistrusted, took it very ill, and was full of indignation, yet was ashamed to change sides back again, or to go away without effecting anything, so that he was forced to follow Nectanabis into the town.
When the enemy came up, and began to draw lines about the town, and to entrench, the Egyptian now resolved upon a battle out of fear of a siege. And the Greeks were eager for it, provisions growing already scarce in the town. When Agesilaus opposed it, the Egyptians then suspected him much more, publicly calling him the betrayer of the king. But Agesilaus, being now satisfied within himself, bore these reproaches patiently, and followed the design which he had laid, of over-reaching the enemy, which was this.
