By midday, the crowds returned around St. Philip Neri's Church. General George Cadwalader ordered the crowds to disperse, but they did not. By the evening, the sheriff had arrived with a 150-strong posse. Throughout the evening, the military presence grew, and three cannons were stationed on the streets. The soldiers cleared the streets near the church, despite being pelted with rocks by the mob. Responding to the rock throwers, General Cadwalader ordered a cannon to be fired at the crowd on Third Street. Former U.S. Congressman Charles Naylor begged the general not to fire; he and several others were arrested and held within the church. By the morning of July 7, most of the soldiers had left, but the crowds, led by an alderman and the sheriff, returned and demanded that the remaining guard release Naylor. Everyone except Naylor was released. The crowds grew, and a cannon was brought from a nearby wharf and used to threaten the church. After further negotiations, Naylor was released and carried home to cheers on people's shoulders.
