All this was true, and the tribunes and prefects heaped on their men the same reproaches. The troops formed themselves in cohorts and companies, for they could not deploy into line, as the enemy were scattered everywhere, while from the fact that the battle was raging within the entrenchments, they were themselves hampered with their tents and baggage. Tutor, Classicus, and Civilis, each at his post, animated the combatants; the Gauls they urged to fight for freedom, the Batavi for glory, the Germans for plunder. Everything seemed in favour of the enemy, till the 21st legion, having more room than the others, formed itself into a compact body, withstood, and soon drove back the assailants. Nor was it without an interposition of heaven, that by a sudden change of temper the conquerors turned their backs and fled. Their own account was, that they were alarmed by the sight of the cohorts, which, after being broken at the first onset, rallied on the top of the hills, and presented the appearance of reinforcements. What checked them in their course of victory was a mischievous struggle among themselves to secure plunder while they forgot the enemy. Cerialis, having thus all but ruined everything by his carelessness, restored the day by his resolution; following up his success, he took and destroyed the enemy's camp on the same day.
