The march of the auxiliaries was guided by the ambassador; and they were admitted, without distrust, into the fortresses of the Alps.
But the crafty tyrant followed, with hasty and silent footsteps, in the rear; and, as he diligently intercepted all intelligence of his motions, the gleam of armor, and the dust excited by the troops of cavalry, first announced the hostile approach of a stranger to the gates of Milan.

In this extremity, Justina and her son might accuse their own imprudence, and the perfidious arts of Maximus; but they wanted time, and force, and resolution, to stand against the Gauls and Germans, either in the field, or within the walls of a large and disaffected city.

Flight was their only hope, Aquileia their only refuge; and as Maximus now displayed his genuine character, the brother of Gratian might expect the same fate from the hands of the same assassin.

Maximus entered Milan in triumph; and if the wise archbishop refused a dangerous and criminal connection with the usurper, he might indirectly contribute to the success of his arms, by inculcating, from the pulpit, the duty of resignation, rather than that of resistance.

The unfortunate Justina reached Aquileia in safety; but she distrusted the strength of the fortifications: she dreaded the event of a siege; and she resolved to implore the protection of the great Theodosius, whose power and virtue were celebrated in all the countries of the West.
