29. This murder exasperated the Thebans, and all the Bœotians, to the most rancorous animosity against the Romans, for they considered that Zeuxippus, one of the first men of the nation, had not been party to such a crime without the instigation of the Roman general. [2] To recommence a war, they had neither strength nor a leader; but they had recourse to private massacres, as being next to war, and cut off many of the soldiers, some as they came to lodge in their houses, others as they wandered about their winter quarters, or were on leave of absence for various purposes. [3] Some were killed on the roads by parties lying in wait in lurking-places; others were seduced and carried away to inns, which were left uninhabited, and there put to death. [4] At last they committed these crimes, not merely out of hatred, but likewise from a desire of booty; for the soldiers on furlough generally carried money in their purses for the purpose of trading. [5] At first a few at a time, afterwards greater numbers used to be missed, until all Bœotia became notorious for those practices, and a soldier went beyond the bounds of the camp with more timidity than into an enemy's country. [6] Quinctius then sent deputies round the states, to make inquiry concerning the murders committed. The greatest number of murders were found to have been committed about the lake called Copais; there the bodies were dug out of the mud, and drawn up out [p. 1470]of the marsh, having had earthen jars or stones tied to them, so as to be dragged to the bottom by the weight. Many deeds of this sort were discovered to have been perpetrated at Acrœphia and Coronea. [7] Quinctius at first insisted that the persons guilty should be given up to him, and that, for five hundred soldiers, (for so many had been cut off,) the Bœotians should pay five hundred talents.¹ [8] Neither of these requisitions being complied with, and the states only making verbal apologies, declaring, that none of those acts had been authorized by the public; Quinctius first sent ambassadors to Athens and Achaia, to satisfy the allies, that the war which he was about to make on the Bœotians was conformable to justice and piety; [9] and then, ordering Publius Claudius to march with one-half of the troops to Acrœphia, he himself, with the remainder, invested Coronea; and these two bodies, marching by different roads from Elatia, laid waste all the country through which they passed. [10] The Bœotians, dismayed by these losses, while every place was filled with fugitives, and while the terror became universal, sent ambassadors to the camp; and as these were refused admittance, the Achaeans and Athenians came to their assistance. [11] The Achaeans had the greater influence as intercessors; inasmuch as they were resolved, in case they could not procure peace for the Bœotians, to join them in the war. [12] Through the mediation of the Achaeans, however, the Bœotians obtained admission and an audience of the Roman general; who, ordering them to deliver up the guilty, and to pay thirty talents² as a fine, granted them peace, and raised the siege.
