Meanwhile the campaign had opened favourably for Otho, at whose bidding the armies of Dalmatia and Pannonia had begun to move. These comprised four legions from each of which two thousand troops were sent on in advance. The 7th had been raised by Galba, the 11th, 13th, and 14th were veteran soldiers, the 14th having particularly distinguished itself by quelling the revolt in Britain. Nero had added to their reputation by selecting them as his most effective troops. This had made them long faithful to Nero, and kindled their zeal for Otho. But their self-confidence induced a tardiness of movement proportionate to their strength and solidity. The auxiliary infantry and cavalry moved in advance of the main body of the legions. The capital itself contributed no contemptible force, namely five Prætorian cohorts, some troops of cavalry, and the first legion, and together with these, 2000 gladiators, a disreputable kind of auxiliaries, but employed throughout the civil wars even by strict disciplinarians. Annius Gallus was put at the head of this force, and was sent on with Vestricius Spurinna to occupy the banks of the Padus, the original plan of the campaign having fallen to the ground, now that Cæcina, who they had hoped might have been kept within the limits of Gaul, had crossed the Alps. Otho himself was accompanied by some picked men of the body-guard, with whom were the rest of the Prætorian cohorts, the veteran troops from the Prætorian camp, and a vast number of the levies raised from the fleet. No indolence or riot disgraced his march. He wore a cuirass of iron, and was to be seen in front of the standards, on foot, rough and negligent in dress, and utterly unlike what common report had pictured him.
