After Naylor was brought home, the mob attacked the church, damaging a wall with the cannon. A second cannon was brought from the wharfs and fired at the church, after which the mob pelted the building with rocks and broke in through a side door. The soldiers fired on the men breaking into the church, who promptly retreated. After retreating, the nativists negotiated with the guard, who agreed to withdraw, allowing the nativists to guard the church. The crowd pelted the soldiers with rocks and some soldiers fired back, which only incited the mob further. The mob forced its way into the church, causing extensive damage to the interior. After about an hour, a group of twenty men organized themselves to guard St. Philip Neri's, and the mob left the church.
