During the Civil War, compasses were used by both the North and South for many reasons. At that time, people used the sun, stars, moon, currents, and wind to find their way around. But, clouds and other elements of nature can make that kind of navigation hard. So compasses were important tools. Armies used compasses to help make maps, track the movement of troops, and locate enemy forces.
