Athens: Its Rise and Fall, Book V. by Lytton, Edward Bulwer Lytton, Baron, 1803-1873

VI. The inglorious result of the Peloponnesian expedition into Attica naturally tended to make the Spartans desirous of peace upon honourable terms, while the remembrance of dangers, eluded rather than crushed, could not fail to dispose the Athenian government to conciliate a foe from whom much was to be apprehended and little gained. Negotiations were commenced and completed (B. C. 445). The Athenians surrendered some of the most valuable fruits of their victories in their hold on the Peloponnesus. They gave up their claim on Nisaea and Pegae--they renounced the footing they had established in Troezene--they abandoned alliance or interference with Achaia, over which their influence had extended to a degree that might reasonably alarm the Spartans, since they had obtained the power to raise troops in that province, and Achaean auxiliaries had served under Pericles at the siege of Oeniadae [259]. Such were the conditions upon which a truce of thirty years was based [260]. The articles were ostensibly unfavourable to Athens. Boeotia was gone--Locris, Phocis, an internal revolution (the result of Coronea) had torn from their alliance. The citizens of Delphi must have regained the command of their oracle, since henceforth its sacred voice was in favour of the Spartans. Megara was lost--and now all the holds on the Peloponnesus were surrendered. These reverses, rapid and signal, might have taught the Athenians how precarious is ever the military eminence of small states. But the treaty with Sparta, if disadvantageous, was not dishonourable. It was founded upon one broad principle, without which, indeed, all peace would have been a mockery--viz., that the Athenians should not interfere with the affairs of the Peloponnesus. This principle acknowledged, the surrender of advantages or conquests that were incompatible with it was but a necessary detail. As Pericles was at this time in office [261], and as he had struggled against an armed interference with the Boeotian towns, so it is probable that he followed out his own policy in surrendering all right to interfere with the Peloponnesian states. Only by peace with Sparta could he accomplish his vast designs for the greatness of Athens-- designs which rested not upon her land forces, but upon her confirming and consolidating her empire of the sea; and we shall shortly find, in our consideration of her revenues, additional reasons for approving a peace essential to her stability.
