396 THE DECLINE AND FALL Valentinian m. emperor of the West. A.D. 425-455 dently entrusted to Ardaburius and his son Aspar, who had ah'eady signalized their valour af^ainst the Persians. It was resolved that Ardaburius should embark with the infantry ; whilst Aspar, at the head of the cavalry, conducted PlaeicUa and her son 'alentinian along the sea-coast of the Hadriatic. The march of the cavalry was performed with such active dili- gence that they surprised, without resistance, the important city of Aquileia ; when the liopes of Aspar were unexpectedly confounded by the intelligence that a storm had dispersed the Imperial fleet ; and that his father, with only two galleys, was taken and carried a prisoner into the ])ort of Ravenna. Yet this incident, unfortunate as it might seem, faciliUxted the con- quest of Italy.
