What did a drummer boy do in the mrevolutionary war?

Drummer boys had a tough life....they would mostly perform chores,obery orders,and get along with their mates. This was especially hard since most were younger than 12, and lied about their age. Although other drummer boys were between the ages of 12 and 16. Drummer boys led their army with the beat of their drums and also were used to communicate when voices werent load enough.
