Cassius Dio Cocceianus, Dio's Rome, Volume 1
“ Thus, under compulsion, Hanno left Messana entirely. The Carthaginians disciplined him and sent a herald to the Romans bidding them leave Messana and depart from all of Sicily by a given day; they also set [Pg 163] an army in motion. Since the Romans paid no heed, they put to death the mercenaries serving with them who were from Italy, and made an assault upon Messana, Hiero accompanying them. Then for a season they besieged the city and kept guard over the strait, to prevent any troops or provisions being conveyed to the foe. ”
