Ita amborum exercitu coniuncto, Marium iam in hiberna proficiscentem vix decuma parte die relicua invadunt, rati noctem, quae iam aderat, et victis sibi munimento fore et, si vicissent nullo inpedimento, quia locorum scientes erant, contra Romanis utrumque casum in tenebris difficiliorem fore.
So, after the armies of both kings had been united, they attacked Marius while he was now departing for winter quarters, when scarcely a tenth part of the day was left. For they thought that the night, which was at hand, would offer them protection in case of defeat and would be no hindrance, if they were victorious because they had knowledge of the locale; for the Romans, by contrast, either outcome of the battle would be more difficult in the darkness.
