The Eddy house served as the regimental hospital while the camp was in use, and the surrounding campsite is counted as contributing. It is significant at the local level.","narrative":"On the eastern outskirts of Shawneetown, Illinois, a 196-acre farm preserves the site of Camp Mather and Camp Logan, Civil War recruiting and training camps. At its center is a one-and-a-half-story red brick house, built around 1838-1839 by Henry Eddy, a regional Whig political leader, newspaper founder and lawyer, as the summer home of a working farm. Its original plan was a row of single rooms, each opening to the porch through its own door, with three dormers above. From October 1861 through March 1863 the surrounding fields hosted Federal regiments assembling from their home counties, and the Eddy house served as the regimental hospital. Records from the period describe measles and deaths among the troops, and winter flooding that cut the camp off from town. The rural setting, house and fields remain largely intact, and this wartime role is the basis for its local significance. Later additions include a 1975 apartment and garage, and several farm buildings postdate the war.","period_of_significance":"1861-1863","architect_builder":"Unknown (house built by its first owner, Henry Eddy)","architectural_style":"Mid-19th Century vernacular, with no attributed sub-type","criteria":["A"],"status_note":"Described as a single-family dwelling in current use; the surrounding land is an open farm field planted in wheat.
