In her position, he asserted, no Grecian power either would or could have acted otherwise—no Grecian power, certainly not Sparta, would have acted with so much equity and moderation or given so little ground of complaint to her subjects. Worse they had suffered, while under Persia; worse they would suffer, if they came under Sparta, who held her own allies under the thraldom of an oligarchical party in each city; and if they hated Athens this was only because subjects always hated the present dominion, whatever that might be.
Having justified both the origin and the working of the Athenian empire, the envoy concluded by warning Sparta to consider calmly, without being hurried away by the passions and invectives of others, before she took a step from which there was no retreat, and which exposed the future to chances such as no man on either side could foresee. He called on her not to break the truce mutually sworn to, but to adjust all differences, as Athens was prepared to do, by the amicable arbitration which that truce provided. Should she begin war, the Athenians would follow her lead and resist her, calling to witness those gods under whose sanction the oaths were taken. At any time previous to the affair of Corcyra, the topics insisted upon by the Athenian would probably have been profoundly listened to at Sparta. But now the mind of the Spartans was made up. Having cleared the assembly of all “strangers,” and even all allies, they proceeded to discuss and determine the question among themselves. Most of their speakers held but one language—expatiating on the wrongs already done by Athens, and urging the necessity of instant war. There was however one voice, and that a commanding voice, raised against this conclusion: the ancient and respected king Archidamus opposed it.
The speech of Archidamus is that of a deliberate Spartan, who, setting aside both hatred to Athens and blind partiality to allies, looks at the question with a view to the interests and honour of Sparta only. He reminded them of the wealth, the population (greater than that of any other Grecian city), the naval force, the cavalry, the hoplites, the large foreign dominion of Athens—and then asked by what means they proposed to put her down. Ships, they had few; trained seamen, yet fewer; wealth, next to none. They could indeed invade and ravage Attica, by their superior numbers and land-force. But the Athenians had possessions abroad sufficient to enable them to dispense with the produce of Attica, while their great navy would retaliate the like ravages upon Peloponnesus. To suppose that one or two devastating expeditions into Attica would bring the war to an end, would be a deplorable error; such proceedings would merely enrage the Athenians, without impairing their real strength, and the war would thus be prolonged, perhaps for a whole generation. Before they determined upon war, it was absolutely necessary to provide more efficient means for carrying it on; and to multiply their allies not merely among the Greeks, but among foreigners also. While this was in process, envoys ought to be sent to Athens to remonstrate and obtain redress for the grievances of the allies. If the Athenians granted this—which they very probably would do, when they saw the preparations going forward, and when the ruin of the highly-cultivated soil of Attica was held over them
The speech of Archidamus was not only in itself full of plain reason and good sense, but delivered altogether from the point of view of a Spartan; appealing greatly to Spartan conservative feeling and even prejudice. But in spite of all this, and in spite of the personal esteem entertained for the speaker, the tide of feeling in the opposite direction was at that moment irresistible. Sthenelaidas, one of the five ephors to whom it fell to put the question for voting, closed the debate. His few words mark at once the character of the man, the temper of the assembly, and the simplicity of speech, though without the wisdom of judgment, for which Archidamus had taken credit to his countrymen.
