Was there a Confederate POW camp in or near Helena Arkansas during the Civil War? My great granduncle, Samuel Friend (a Union soldier), stated he was a POW in Helena, Arkansas for six weeks and returned to his unit after a prisoner exchange. According to most military history of the area in the later part of 1862, Helena was occupied by the Union army. Is there information about those who were in the POW camp in that area?

Thanks,
Matt Friend
