Leisure activities were similar in both the Union and Confederate army and most free time was spent writing letters home. Soldiers were prolific letter writers and wrote at every opportunity. It was the only way for them to communicate with loved ones and inform the home folks of their condition and where they were. Thrifty soldiers sent their pay home to support their families and kept only a small amount to see them through until the next payday. The arrival of mail in camp was a cause for celebration no matter where the soldiers were and there was sincere grumbling when the mail arrived late. The lucky soldiers who received a letter from home often read and re-read them many times. Packages from home contained baked goods, new socks or shirts, underwear, and often soap, towels, combs, and toothbrushes. Union soldiers often spent their free time at the sutler's store, comparable to the modern post exchange, where they could purchase toiletries, canned fruit, pocketknives, and other supplementary items, but usually at exorbitant prices. A private's salary amounted to $13.00 per month in 1863 and those unfortunates who owed the sutler watched as most of their pay was handed over to the greedy businessman on pay day. Confederates did not have the luxury of sutlers, who disappeared soon after the war began. Instead they depended on the generosity of folks at home or farmers and businessmen near the camps.

Free time was also spent in card games, reading, pitching horseshoes, or team sports such as the fledgling sport of baseball, a game which rapidly gained favor among northern troops. Rule booklets were widely distributed and the game soon became a favorite. Soldiers also played a form of football that appeared more like a huge brawl than the game we know today, and often resulted in broken noses and fractured limbs. Holidays were celebrated in camp with feasts, foot races, horse racing, music, boxing matches, and other contests. But while on active campaign, the soldiers were limited to writing, cleaning uniforms and equipment, and sleeping.
