13 I heard that the Basilica was surrounded by the groaning of the people, but while the lessons were being read, I was informed that the new Basilica also was full of people, that the crowd seemed greater than when they were all free, and that a Reader was being called for. In short, the soldiers themselves who seemed to have occupied the Basilica, when they knew that I had ordered that the people should abstain from communion with them, began to come to our assembly. When they saw this, the minds of the women were troubled, and one rushed forth. But the soldiers themselves said that they had come for prayer not for fighting. The people uttered some cries. With great moderation, with great instancy, with great faithfulness they begged that we would go to that Basilica. It was said, too, that the people in that Basilica were demanding my presence.
