The eunuch seems to have led his army round the head of the Adriatic Gulf.
The conduct of a new campaign was entrusted to the eunuch Narses; Totila marched against him and was defeated and killed at the battle of Tagina in July 552.
The emperor at last complied, and in 552 a powerful army was despatched under Narses, an Armenian eunuch now advanced in life, but reputed the most skilful general of the age, as Belisarius was the hottest soldier.
This was Bardas Sclerus, whom the eunuch deposed from his post of general in the East.
Belisarius wrote to the eunuch pointing out the necessity of unity of purpose in the imperial army.
He denies that the precedents of the eunuch baptized by Philip or of Paul baptized without hesitation by Simon (to which the other party appealed) were relevant.
Their maritime importance compelled Narses, the imperial commander, to seek their aid in transporting his army from Grado; and when the Paduans appealed to the Eunuch to restore their rights over the Brenta, the Venetians replied by declaring that islands of the lagoon and the river mouths that fell into the estuary were the property of those who had rendered them habitable and serviceable.
