Fort Delaware is located on Pea Patch Island, between New Jersey and Delaware in the middle of the Delaware River. The prisoners referred to this as "Devil's Half Acre".

Joseph and William both survived the ordeal and returned to their families in Tennessee. Joseph migrated with them to Indiana before returning to farm in Jefferson County, Tennessee.
In Brian Temple's The Union Prison at Fort Delaware: A Perfect Hell on Earth, he describes the conditions at Pea Patch Island in July and August 1863 as "the heat could be so intense that there were days where 'men by the hundreds are seen sweltering on their backs, fairly gasping for breath, like fish dying on a sand beach.'" The men there faced poor water and food conditions, often resorting to eating rats.
The following correspondence comes from War of the Rebellion: A Compilation of the Official Records of the Union and Confederate Armies (see Google Books):
Joseph and William were in the group of prisoners transferred from Fort Delaware to Point Lookout in September 1863. Detail on Point Lookout will be provided in a future post.
Update - I've corrected this post to note that Joseph was not alone as a prisoner of war, he was with his brother-in-law, William. This may be one of the reasons that they both survived through 3 months at Fort Delaware and almost 5 months at Point Lookout before they were set free.
