The Confederate Government was unable to provide housing, food, shelter, clothing, and medical care for all the prisoners. the prison was only made to hold about 10,000 prisoners but it got very crowded and ended up with as many as 45,613 prisoners.
After the prison site was selected, Captain Richard B. Winder was sent to Andersonville to construct a prison. Arriving in late December of 1863, Captain Winder designed the prison that encircle roughly 16.5 acres which he felt was large enough to hold 10,000 prisoners. The prison was to be rectangular in shape with a small creek flowing roughly through the center of the compound. The prison was given the name Camp Sumter. It was intended as a place where prisoners could be watched by a few amount of soldiers at a time.
Over 45,000 Union soldiers went to Andersonville during the 14 months that it was in existence. Of these, 12,912 died from disease, overcrowding, or exposure. They were buried shoulder to shoulder in trenches near the prison.
Here are some of the sites that I used to gather my information:
