To obviate such a defeat of his plans, he resorted to a singular manœuvre. One of the Lacedæmonian envoys, Endius, was his private guest, by an ancient and particular intimacy subsisting between their two families.[69] This probably assisted in procuring for him a secret interview with the envoys, and enabled him to address them with greater effect, on the day before the meeting of the public assembly, and without the knowledge of Nikias. He accosted them in the tone of a friend of Sparta, anxious that their proposition should succeed; but he intimated that they would find the public assembly turbulent and angry, very different from the tranquil demeanor of the senate: so that if they proclaimed themselves to have come with full powers of settlement, the people would burst out with fury, to act upon their fears and bully them into extravagant concessions. He therefore strongly urged them to declare that they had come, not with any full powers of settlement, but merely to explain, discuss, and report: the people would then find that they could gain nothing by intimidation, explanations would be heard, and disputed points be discussed with temper, and he (Alkibiadês) would speak emphatically in their favor. He would advise, and felt confident that he could persuade, the Athenians to restore Pylos, a step which his opposition had hitherto been the chief means of preventing. He gave them his solemn pledge—confirmed by an oath, according to Plutarch—that he would adopt this conduct, if they would act upon his counsel.[70] The envoys were much struck with the apparent sagacity of these suggestions,[71] and still more delighted to find that the man from whom they anticipated the most formidable opposition was prepared to speak in their favor. His language obtained with them, probably, the more ready admission and confidence, inasmuch as he had volunteered his services to become the political agent of Sparta only a few months before; and he appeared now to be simply resuming that policy. They were sure of the support of Nikias and his party, under all circumstances; if, by complying with the recommendation of Alkibiadês, they could gain _his_ strenuous advocacy and influence also, they fancied that their cause was sure of success. Accordingly, they agreed to act upon his suggestion, not only without consulting but without even warning Nikias, which was exactly what Alkibiadês desired, and had probably required them to promise.
