Exploits of valour and intrepidity may be discovered in the history of every nation. But the revolution of Thebes displayed not less wisdom of design, than enterprising gallantry in execution. Amidst the tumult of action, and ardour of victory, the conspirators possessed sufficient coolness and foresight to reflect that the Cadmea, or citadel, which was held by a Lacedæmonian garrison of fifteen hundred men, would be reinforced, on the first intelligence of danger, by the resentful activity of Sparta. To anticipate this alarming event, which must have rendered the consequences of the conspiracy incomplete and precarious, they commanded the messenger, whom, immediately after the destruction of the tyrants, they had despatched to their friends in the Thriasian plain, to proceed to Athens, in order to communicate the news of a revolution which could not fail to be highly agreeable to that state, and to solicit the immediate assistance of the Athenians, whose superior skill in attacking fortified places was acknowledged by Greeks and barbarians. This message was attended with the most salutary effects. The acute discernment of the Athenians eagerly seized the precious opportunity of weakening Sparta, which, if once neglected, might never return. Several thousand men were ordered to march; and no time was lost, either in the preparation, or in the journey, since they reached Thebes the day after Pelopidas had re-established the democracy. The seasonable arrival of those auxiliaries, whose celerity exceeded the most sanguine hopes of the Thebans, increased the ardour of the latter to attack the citadel. The events of the siege are variously related. According to the most probable account, the garrison made a very feeble resistance, being intimidated by the impetuous alacrity and enthusiasm, as well as the increasing number of the assailants, who already amounted to fourteen thousand men, and received continual accessions of strength from the neighbouring cities of Bœotia. Only a few days had elapsed, when the Lacedæmonians desired to capitulate, on condition of being allowed to depart in safety with their arms. Their proposal was readily accepted; but they seem not to have demanded, or at least not to have obtained, any terms of advantage or security for those unfortunate Thebans whose attachment to the Spartan interest strongly solicited their protection. At the first alarm of sedition, these unhappy men, with their wives and families, had taken refuge in the citadel. The greater part of them cruelly perished by the resentment of their countrymen; a remnant only was saved by the humane interposition of the Athenians. So justly had Epaminondas suspected, that the revolution could not be accomplished without the effusion of civil blood.[f] THE SECOND ATHENIAN LEAGUE [Sidenote: [379-378 B.C.]]
