The Roman History · Amm. 31.7.10

Therefore the next day, as soon as it was light, the signal for taking arms having been given by the trumpets on both sides, the barbarians, after having, in accordance with their usual custom, taken an oath to remain faithful to their standards, attempted to gain the higher ground, in order that from it they might descend down the steep like wheels, overwhelming their enemy by the vigour of their attack. When this was seen, our soldiers all flocked to their proper regiments, and then stood firm, neither turning aside nor in any instance even leaving their ranks to rush forward.
