Archaeologists have discovered a POW camp in southeastern Georgia that was briefly used to house Union soldiers.  Since they had to leave in a hurry to flee the advance of Sherman’s army, a lot of interesting artifacts were left behind.  If you’re interested, here’s a link to the article:

For those of you in Chicago.  We had a POW camp here as well in the Bronzeville area:  Camp Douglas.  It housed Confederate POWs.  No traces of the site itself remain.  It was built over years ago.  But a monument does exist at Oak Woods Cemetary to commemorate the many unknown dead from the camp, called Confederate Mound.
