Here again, we see the superiority of the narrative of Xenophon over that of Diodorus. According to the former, these Lacedæmonian commanders surrendered the Kadmeia without any resistance at all. Their condemnation, like that of the Athenian two generals, becomes a matter easy to understand and explain. Even before the Lacedæmonian envoys had quitted Athens, however, an incident, alike sudden and memorable, completely altered the Athenian temper. The Lacedæmonian harmost Sphodrias (whom Kleombrotus had left at Thespiæ to prosecute the war against Thebes), being informed that Peiræus on its land side was without gates or night watch,—since there was no suspicion of attack,—conceived the idea of surprising it by a night-march from Thespiæ, and thus of mastering at one stroke the commerce, the wealth, and the naval resources of Athens. Putting his troops under march one evening after an early supper, he calculated on reaching the Peiræus the next morning before daylight. But his reckoning proved erroneous. Morning overtook him when he had advanced no farther than the Thriasian plain near Eleusis; from whence, as it was useless to proceed farther, he turned back and retreated to Thespiæ; not, however, without committing various acts of plunder against the neighboring Athenian residents. This plan against Peiræus appears to have been not ill conceived. Had Sphodrias been a man competent to organize and execute movements as rapid as those of Brasidas, there is no reason why it might not have succeeded; in which case the whole face of the war would have been changed, since the Lacedæmonians, if once masters of Peiræus, both could and would have maintained the place. But it was one of those injustices, which no one ever commends until it has been successfully consummated,—“consilium quod non potest laudari nisi peractum.[206]” As it failed, it has been considered, by critics as well as by contemporaries, not merely as a crime but as a fault, and its author Sphodrias as a brave man, but singularly weak and hot-headed.[207] Without admitting the full extent of this censure, we may see that his present aggression grew out of an untoward emulation of the glory which Phœbidas, in spite of the simulated or transient displeasure of his countrymen, had acquired by seizing the Kadmeia. That Sphodrias received private instructions from Kleombrotus (as Diodorus states) is not sufficiently proved; while the suspicion, intimated by Xenophon as being abroad, that he was wrought upon by secret emissaries and bribes from his enemies the Thebans, for the purpose of plunging Athens into war with Sparta, is altogether improbable;[208] and seems merely an hypothesis suggested by the consequences of the act,—which were such, that if his enemies had bribed him, he could not have served them better.
