CLEP U.S. History I 027: Lexington, Concord, and the Move toward Independence
U.S. History to 1877 | Chapter 6 | Lesson 6.1
By early 1775, Massachusetts patriots had formed committees, stored military supplies, and trained militia. General Thomas Gage sent British troops toward Concord to seize arms and possibly arrest leaders. Fighting at Lexington on April 19 left militiamen dead. At Concord and along the return to Boston, militia inflicted serious losses. Who fired first at Lexington remains uncertain, but the political result was clear: bloodshed turned a constitutional dispute into open war.
Militia forces surrounded Boston, and the Second Continental Congress met in Philadelphia. It created a Continental Army and appointed George Washington commander, giving the New England fighting a continental symbol. At the same time, Congress sent the Olive Branch Petition professing loyalty and seeking peace. This apparent contradiction reflected divided expectations. Delegates could prepare defense while hoping the king would restrain Parliament.
The Battle of Bunker Hill in June 1775, fought mainly on Breed’s Hill, ended in British occupation of the position but heavy British casualties. It showed that inexperienced colonial forces could impose great cost. King George III declared the colonies in rebellion and refused the Olive Branch approach. British plans to use force, including hiring German troops, further weakened attachment to monarchy.
Independence emerged through escalation, not a single awakening. Local committees displaced royal authority. Warfare demanded money and alliances. And royal rejection narrowed compromise. Yet Loyalism remained substantial and many people tried to avoid either side. The historian should explain why possibilities closed without reading July 1776 backward into April 1775.
