They soon saw that it would be too difficult a task to relieve the island, so they begged Eurymedon to grant a truce until they sent ambassadors to Athens to sue for peace. Their request was granted, and the Spartan ambassadors at once set sail for Athens. When they entered the assembly, Athens, had she but known it, might have ended the war with honour. But Pericles was no longer there to tell her that to do so would be well. Cleon still ruled the assembly with his rough eloquence. Nicias, the leader of those who desired peace, although he bitterly disliked Cleon, was not strong enough to overthrow him. The assembly, urged by its leader, offered the Spartan ambassadors terms which it knew they would not accept. After rejecting them, as the Athenians expected, the ambassadors returned indignant to Pylos, and the truce was at an end. But Sphacteria was not taken so easily as the Athenians had dreamed. In spite of the strict blockade, food was taken to the island, so that the Spartans were in no danger of starving. Sometimes swimmers carrying with them linseed, poppy seeds and honey, reached the island. Sometimes Helots, tempted by promise of freedom, would manage, when the sky was dark and the sea stormy, to sail past the enemy’s ships, taking cheese, meal and even wine to the Spartans. In Athens, the people were growing impatient of the long blockade. When Demosthenes sent messengers to the city to ask for reinforcements, they began to be sorry that they had not offered more reasonable terms to the ambassadors. They looked darkly at Cleon, and began to whisper that but for his counsel peace would certainly have been made. A meeting of the assembly was called, and Cleon, losing his temper when Nicias urged that peace should be arranged without delay, said, ‘It would be easy enough to take Sphacteria if our generals were men. If I were general I would do it at once.’ Nicias was a quiet man, but these scornful words roused him to anger, and he retorted that if Cleon thought he was able to take the island it would be well that he should go and do so. He was himself a general, while Cleon was only a leather-merchant, but he was willing to resign in his favour. At first Cleon thought that Nicias was but jesting, and he pretended that he really wished to go to the help of Demosthenes. But when he found that his opponent was in earnest, he declined the honour, saying that while Nicias was a general, he himself had no training in military affairs. But the people were not willing to let the leather-merchant escape the consequences of his rash words. They shouted that he must go and prove that he could do as he had said. When Cleon saw that there was no escape he grew reckless, and boasted that he would not only go to Sphacteria, but that he would take the island within twenty days, and either kill all the Spartans on it or bring them prisoners to Athens.
