It is clear that the Bishop of Hippo could scarcely have given any other advice to the Count of Africa. To play the part of political counsellor in the very entangled state of affairs was extremely risky. How was it possible to exhort a victorious general to lay down his arms before the conquered? And yet, in estimating the situation from the Christian standpoint alone, Augustin had found a way to say everything essential, all that could profitably be said at the moment. How did Boniface take a letter which was, in the circumstances, so courageous? What we know is that he did not alter his plans. It would indeed have been very difficult for him to withdraw and yield; and more than ever since a new army under Sigisvultus had been sent against him in all haste. A real fatality compelled him to remain in revolt against Rome. Did he believe he was ruined, as has been stated, or else, through his family connections--let us remember that his wife was a Barbarian--had he been for a long time plotting with Genseric to divide Africa? He has been accused of that. What comes out is, that as soon as he heard of the arrival of Sigisvultus and the new expeditionary force, he called in the Vandals to his aid. This was the great invasion of 429. Ere long, the Barbarians entered Numidia. The borderlands about Hippo were threatened. Stricken with terror, the inhabitants in a mass fled before the enemy, leaving the towns empty. Those who were caught in them rushed into the churches, imploring the bishops and priests to help them. Or else, giving up all hope of life, they cried out to be baptized, confessed, did penance in public. The Vandals, as we have seen, aimed specially at the clergy; they believed that the Catholic priests were the soul of the resistance. Should not these priests, then, in the very interest of the Church, save themselves for quieter times, and escape the persecution by flight? Many sheltered themselves behind the words of Christ: "When they persecute you in this city, flee ye into another."
