Much irritation had been caused among the Athenians by the shifting and treacherous conduct of the Spartans, who had failed to redeem their sworn pledges, and had excited great suspicion at Athens by repeated intrigues with Argos, and with their own offended allies of the Peloponnesian League. Alcibiades had a private grudge against the Spartans, to whom he had made overtures of friendship and service at the time when the treaty was under discussion, only to be set aside as a profligate and frivolous youth, unfit to meddle with serious matters of state. He now placed himself at the head of the party hostile to Sparta, and it was not long before he had an opportunity of revenging the insult to his pride. He used all his influence to promote an alliance with Argos, the ancient enemy and rival of Sparta in Peloponnesus; and when envoys arrived from Sparta to remonstrate against this proceeding, and reassure the Athenians as to their intentions, he contrived by a masterpiece of low cunning to cover them with shame and contempt. When the envoys were introduced to the senate they declared that they had come with full powers to settle all differences, and Alcibiades feared that if they made the same statement to the general assembly of the citizens, they might induce the Athenians to renounce their alliance with Argos. So, after the senate had risen, he took the envoys aside, and with an air of great candour and friendliness warned them that they must conceal the extent of their powers when they appeared before the popular assembly. "You do not understand," he said, "how to deal with the mob of Athens; if you show your hand, they will force you into extravagant concessions. Leave the matter to me, and everything will turn out as you wish." The simple Spartans fell into the snare. They were not at all startled by the proposal that they should eat their own words, for in dishonesty they were not behind Alcibiades himself, though they were no match for him in cunning. Being brought before the people, and asked whether they had come with full powers, they answered bluntly "No!" Great was the amazement at this flat contradiction of the avowal which they had made before the senate, and Alcibiades, giving voice to the general indignation, overwhelmed the astonished envoys with a torrent of invective and abuse. The Spartans were dumb-foundered by his perfidy, and looked helplessly at Nicias, the staunch friend and supporter of Sparta, whom they had forsaken for this shameless young reprobate. Nicias, who of course knew nothing of the trick, was utterly confounded by the double-dealing of the envoys, and could do nothing to relieve their embarrassment. The result was that the envoys were abruptly dismissed, and after a fruitless mission of Nicias to Sparta, which only served to lower his own reputation, the Athenians entered heart and soul into the Argive alliance.
