Final answer:
The colonists needed guns and ammunition to defend themselves from perceived British aggression during the American Revolution.
Step-by-step explanation:
The colonists needed guns and ammunition in order to defend themselves and their rights from perceived British aggression. By the time of the American Revolution, tensions between the American colonies and the British government had escalated, and the colonists felt the need to protect themselves and their communities. They formed militias, such as the Minutemen, who were ready to mobilize quickly to defend their homes and communities in case of conflict. Stockpiling weapons and gunpowder was a way for the colonists to prepare for potential hostilities with the British forces.
