4. Lucius Cornelius the consul, having finished what had to be done in Rome, issued his edict before the assembly that the soldiers whom he personally had enlisted as reinforcements and those who were among the Brutti with Aulus Cornelius the propraetor should all assemble on the Ides of July¹ at Brundisium. [2] He named also three lieutenants, Sextus Digitius, Lucius Apustius and Gaius Fabricius Luscinus, who were to collect ships at Brundisium from all along the sea-coast; and having now made everything ready set out from the City in uniform. About five thousand volunteers, Romans and allies, who had earned their discharges under the command of Publius Africanus, attended the consul as he was setting out and gave in their names for service with him.² [3] About the time the consul departed to the war, during the ludi Apollinares,³ on the fifth day before the Ides of July, in a clear sky during the day, the light was dimmed since the moon passed before the circle of the [4] sun.⁴ Lucius Aemilius [6] [p. 303]Regillus, to whom the naval appointment had fallen,⁵ also departed at the same time. Lucius Aurunculeius was entrusted by the senate with the task of building thirty quinqueremes and twenty triremes, since the rumour was that Antiochus after the naval battle was fitting out a very much larger fleet.⁶

The Aetolians, after their ambassadors [7] had brought back the word from Rome that there was no hope for peace, although their whole coast which faces the Peloponnesus had been ravaged by the Achaeans, thinking more of their [8] danger than of their losses, in order to bar the road against the Romans, seized Mount Corax;⁷ for they had no doubt that they would return at the beginning of spring to besiege Naupactus.⁸ Acilius, because he knew that this was their expectation, thought it better to try [9??] something unforeseen and to attack Lamia;⁹ for the people had both been brought nigh to destruction by Philip and, just because at that time they feared nothing of the kind, he thought that they could be more easily taken by [10??] surprise. Setting out from Elatia he first encamped in hostile territory near the Spercheus river; thence he moved his standards by night and at daybreak attacked the walls from a girdle of entrenchments.
