During historical military campaigns, soldiers often brought various musical instruments to help pass the time in camps. Commonly, these included:
Banjos: Lightweight and portable, banjos were popular among soldiers for playing folk and upbeat melodies.
Fiddles: Often used for traditional tunes and lively camp dances, the fiddle was a favored choice.
Guitars: Providing accompaniment for songs and ballads, guitars also held a steady presence in camps.
These instruments were cherished for their ability to lift spirits and provide a comforting reminder of home during the long and often difficult periods of encampment. Drums and bugles were also a staple in military life, used for communication and signaling, but for personal recreation, banjos, fiddles, and guitars were more prevalent among individual soldiers Source.
