I am trying to track down a soldier in the Second Indiana Light Artillery who was captured at the battle of Poison Spring, Arkansas, on April 18, 1864. Four men are listed in the after action report as not having returned to camp after the battle. I know that Levi H. Burgess died in a prison camp and Charles Van De Venter is listed in the Adjutant General's report as missing in action. That leaves Alonzo Hinshaw (who I'm pretty sure went to a Texas prison camp) and John Highstreet. Does anyone know if I am correct and Highstreet was captured at Poison Spring and escaped a couple of months later?

Thanks for any assistance and, believe it or not, this is a somewhat timely inquiry!
