Logan House’s most historically significant event came eighteen months into the Civil War. Northern support was weakening at that time and Pennsylvania Governor Andrew Curtin decided to organize a meeting to express support for Lincoln and the Union cause. In almost complete secrecy, Governor Curtin assembled the meeting for governors of Union states. Fourteen governors attended the meeting in Altoona, Pennsylvania, on September 24 and 25. This meeting was significant as the Union army hat faltered and Abraham Lincoln had announced plans for emancipation which was not universally supported in the North as a war aim. At this conference, the governors unanimously supported Lincoln which gave the beleaguered President an important victory second only to the battlefield victories in the West and in the Battle of Antietam.
