Which event was a significant indicator of the American colonies' determination to resist British authority?

The Battle of Concord is indeed a significant event that exemplifies the American colonies' resolve to resist British authority. This battle, which took place on April 19, 1775, was part of the larger conflict that erupted between colonial militia and British troops. It marked the first military engagement of the American Revolutionary War. The resistance at Concord demonstrated that the colonies were willing to take up arms against British oppression, showcasing their determination to defend their rights and liberties.

At Concord, the colonial forces successfully repelled the British advance, inflicting casualties and forcing the troops to retreat back to Boston. This act of defiance not only showed the colonists' willingness to fight for their rights but also galvanized support for the revolutionary cause throughout the colonies.

While the Boston Tea Party was a critical moment of protest against British taxation, it was a nonviolent act of defiance rather than direct military engagement. The formation of the Continental Army and the signing of the Declaration of Independence were crucial developments in the fight for independence, but they occurred after the initial military confrontations began at battles like Concord. The Battle of Concord serves as a powerful symbol of the colonies’ collective commitment to resisting British control through armed conflict.
