There are a number of reasons why it would be challenging to run a prison during wartime. One reason is that there would be an increased number of prisoners, as people would be more likely to be arrested for trying to flee the country or for committing crimes in order to survive. There would also be a shortage of staff, as many people would be drafted into the military or would be working in essential wartime industries. This would make it difficult to provide adequate care and supervision for the prisoners. Additionally, there would be a risk of prison breaks, as prisoners would be motivated to escape in order to join the fighting or to try to flee the country. There would also be a risk of attacks from enemy forces, who could target prisons in order to release their own soldiers or to try to capture enemy soldiers.
