Death rates
The overall mortality rates in prisons on both sides were similar, and quite high. Many Southern prisons were located in regions with high disease rates, and were routinely short of medicine, doctors, food and ice. Northerners often believed their men were being deliberately weakened and killed in Confederate prisons, and demanded that conditions in Northern prisons be equally harsh, even though shortages were not a problem in the North.[10]
