218 HISTORY OF GUEECE. them a protection 1 analogous to that which had been conferred by Athens and her powerful fleet, during the interval between the formation of the Confederacy of Delos and the Athenian catas- trophe at Syracuse. At the same time, during the truce, the army had neither occupation nor subsistence. To keep it together and near at hand, yet without living at the cost of friends, was the problem. It was accordingly with great satisfaction that Derkyl- lidas noticed an intimation accidentally dropped by Arakus. Some envoys (the latter said) were now at Sparta from the Thracian Chersonesus (the long tongue of land bordering westward on the Hellespont), soliciting aid against their marauding Thracian neigh- bors. That fertile peninsula, first hellenized a century and a half before by the Athenian Miltiades, had been a favorite resort for Athenian citizens, many of whom had acquired property there during the naval power of Athens. The battle of .ZEgospotami dispossessed and drove home these proprietors, at the same time depriving the peninsula of its protection against the Thracians. It now contained eleven distinct cities, of which Sestos was the most important ; and its inhabitants combined to send envoys to Sparta, entreating the ephors to send out a force for the purpose of building a wall across the isthmus from Kardia to Paktye ; in recompense for which (they said) there was fertile land enough open to as many settlers as chose to come, with coast and harbors for export close at hand. Miltiades, on first going out to the Chersonese, had secured it by constructing a cross-wall on the same spot, which had since become neglected during the pe- riod of Persian supremacy ; Perikles had afterwards sent fresh colonists, and caused the wall to be repaired. But it seems to have been unnecessary while the Athenian empire was in full vigor, since the Thracian princes had been generally either conciliated, or kept off, by Athens, even without any such bulwark." Informed that the request of the Chersonesites had been favorably listened to at Sparta, Derkyllidas resolved to execute their project with his own army. Having prolonged his truce with Pharnabazus, he crossed the Hellespont into Europe, and employed his army during the whole summer hi constructing this cross-wall, about four and ? 1 Compare Xen.
