When the Lacedaemonians had thus spoken, the Athenians, by the advice of Themistocles, answered that they would send ambassadors to them concerning what they spoke of; and immediately dismissed them. And Themistocles advised them to send himself as quickly as possible to Lacedaemon, and having chosen other ambassadors besides himself, not to despatch them immediately, but to wait till such time as they should have raised their wall to the height most absolutely necessary for fighting from; and that the whole population in the city, men, women, and children, should build it, sparing neither private nor public edifice, from which any assistance towards the work would be gained, but throwing down every thing.
After giving these instructions, and suggesting that he would himself manage all other matters there, he took his departure.
On his arrival at Lacedaemon he did not apply to the authorities, but kept putting off and making excuses. And whenever any of those who were in office asked him why he did not come before the assembly, [*]( Or, about his not coming, according to Arnold, who objects to the common mode of explanation, by understanding διὰ before ὅτι.) he said that he was waiting for his colleagues; that owing to some engagement they had been left behind; he expected, however, that they would shortly come, and wondered that they were not already there.
When they heard this, they believed Themistocles through their friendship for him; but when every one else [*]( i.e. those who came from Athens, and could therefore speak to the fact. κατηγορούντων is thought by some to mean, charging him with the fact: but with that signification it would require a genitive case after it, (e.g. ch. 95. 7) and as none is expressed, I have preferred taking it in the more general sense.) came and distinctly informed them that the walls were building, and already advancing to some height, they did not know how to discredit it.
When he found this, he told them not to be led away by tales, but ratter to send men of their own body who were of good character, and would bring back a credible report after inspection.
They despatched them therefore; and Themistocles secretly sent directions about them to the Athenians, to detain them, with as little appearance of it as possible, and not to let them go until they themselves had returned back; (for by this time his colleagues, Abronychus, the son of Lysicles, and Aristides, the son of Lysimachus, had also come to him with the news that the wall was sufficiently advanced;) for he was afraid that the Lacedaemonians, when they heard the truth, might not then let them go.
