On or about this date, the Confederates moved Jens Dahle, and James Everhart, the diarist, from Libby Prison, crossed the James River to Belle Isle. This prison was located an island overlooking Richmond, Virginia. Jens and James stayed at Belle Isle until October of 1864. 
Belle Isle was a “tent” type prison in that there was no permanent structure to house the prisoners who were housed in tents. The James River served as a deterrent to escapes.  This view in the photo is taken looking at Richmond. 
Early in the war, prisoners would be exchanged between the two armies. In April of 1864, General Ulysses S. Grant recognized that this exchange program was advantageous to the Confederates as the Confederate exchanged soldiers went back into the Confederate Army contrary to their oath upon release, whereas the Union soldiers went home. Grant cancelled all further exchanges. Prisons like Belle Isle, sized for 1000 prisoners, swelled almost overnight to many times that number.  This was true for prisons in the north and the south. As a consequence, housing became crude, food shortages were chronic and deaths mounted as sanitary conditions became rudimentary and pathogens infiltrated what water supplies were available. Death became common place. 
Next posting: 8 October 1864. Jens is transferred to Salisbury Prison.
 CMSR, Jens Dahle.
