Problems both the South and the North faced were diseases such as typhoid, pneumonia, and tuberculosis. About twice as many soldiers died of illnesses as died in combat. Both Union and Confederate armies faced shortages of clothing, food, and even rifles. Troops lacked standard uniforms and simply wore their own clothes. Military service meant long hours of drills and many days marching on hot, dusty roads. It was hard to get used to the troubles and demands of army life.
