Camp Hancock was established in July 1917 to serve as a training camp for the Pennsylvania National Guard units who would comprise the 28th “Keystone” Infantry Division, which occupied the camp from August 1917 – May 1918. After the 28th Division embarked for Europe the camp established a machine gun training center. It served as a demobilization center from December 1918 – March 1919 when it was closed.
There is nothing surviving of Camp Hancock in Augusta, and no historical marker, but a resource below from the Augusta Museum has laid out camp locations on a modern map for reference.
