It was at this time that the cohorts of Batavians and 19 Canninefates, on their way to Rome under orders from Vitellius, received the message which Civilis had sent to them. They promptly fell into a ferment of unruly insolence and demanded a special grant as payment for their journey, double pay, and an increase in the number of their cavalry. Although all these things had been promised by Vitellius they had no hope of obtaining them, but wanted an excuse for rebellion. Flaccus made many concessions, but the only result was that they redoubled their vigour and demanded what they felt sure he would refuse. Paying no further heed to him they made for Lower Germany, to join Civilis. Flaccus summoned the tribunes and centurions and debated with them whether he should use force to punish this defiance of authority. After a while he gave way to his natural cowardice and the fears of his subordinates, who were distressed by the thought that the loyalty of the auxiliaries was doubtful and that the legions had been recruited by a hurried levy. It was decided, therefore, to keep the soldiers in camp. However, he soon changed his mind when he found himself criticized by the very men whose advice he had taken. He now seemed bent on pursuit, and wrote to Herennius Gallus in command of the First legion, who was holding Bonn, telling him to bar the path of the Batavians, and promising that he and his army would follow hard upon their heels. The rebels might certainly have been crushed had Flaccus and Gallus each advanced their forces from opposite directions and thus surrounded them. But Flaccus soon gave up the idea, and wrote another letter to Gallus, warning him to let the rebels pass undisturbed. This gave rise to a suspicion that the generals were purposely promoting the war; and all the disasters which had already occurred or were feared in the future, were attributed not to the soldiers’ inefficiency or the strength of the enemy, but to the treachery of the generals.
