In mid-June, 1863--three months after La Salle received its charter--there was panic in Philadelphia as General Robert E. Lee crossed into Pennsylvania and threatened Harrisburg and, potentially, Philadelphia. Frantic calls went out for home guard volunteers to defend the state and the city. After Gettysburg, the medical facilities in Philadelphia were overwhelmed, leading to the use of churches as impromptu hospitals, as shown in this sketch by James Queen.
