The court and the people were astonished by the strange intelligence, that a virtuous hero, after so many favors, and so many services, had renounced his allegiance, and invited the Barbarians to destroy the province intrusted to his command. The friends of Boniface, who still believed that his criminal behavior might be excused by some honorable motive, solicited, during the absence of Ætius, a free conference with the Count of Africa; and Darius, an officer of high distinction, was named for the important embassy. In their first interview at Carthage, the imaginary provocations were mutually explained; the opposite letters of Ætius were produced and compared; and the fraud was easily detected. Placidia and Boniface lamented their fatal error; and the count had sufficient magnanimity to confide in the forgiveness of his sovereign, or to expose his head to her future resentment. His repentance was fervent and sincere; but he soon discovered that it was no longer in his power to restore the edifice which he had shaken to its foundations. Carthage and the Roman garrisons returned with their general to the allegiance of Valentinian; but the rest of Africa was still distracted with war and faction; and the inexorable king of the Vandals, disdaining all terms of accommodation, sternly refused to relinquish the possession of his prey. The band of veterans who marched under the standard of Boniface, and his hasty levies of provincial troops, were defeated with considerable loss; the victorious Barbarians insulted the open country; and Carthage, Cirta, and Hippo Regius, were the only cities that appeared to rise above the general inundation.
