On August 21, 1865, the steamboat, USS Argosy (Number 3) was returning Union soldiers of the 70th Ohio Infantry home via the Ohio River. The steamer was forced aground by a storm. Her boilers exploded and caused ten fatalities. They were buried in a mass grave one half mile from Magnet (then called Rono, Indiana). Ten grave makers were raised at the site.[1]
Local Perry County (Indiana) historian Bert Fenn discovered information that suggested one of the ten who was supposedly buried in the grave may have actually lived until arriving in Louisville, where he died.[2] [3] This could explain why one of the soldiers buried in the grave is an unknown soldier.The Civil War Memorial Grave historical marker at the site erected by the Indiana Civil War Centennial Commission in 1965.
Ironically one of the first vessels to arrive at the disaster was Steamboat USS Argosy No.27. For a picture and the later career of the USS Argosy Number 3 see the entry in Waterways Journal 2018[4]
