The Morning of Lexington
Dawn alert on the common
As dawn broke on April 19 1775, colonial militiamen gathered on Lexington Green after receiving word that British troops were advancing.
Captain John Parker positioned his small company to observe the road, seeking to avoid a confrontation while still demonstrating resolve in the face of a superior force.
Orders and ambiguous signals
Accounts differ on whether Parker intended to disperse or stand his ground, and on whether a shot was triggered by a single soldier or by an unknown party in the confusion.
The brief standoff ended with casualties on both sides, transforming the march of the British into the first exchange of fire of the Revolutionary War.
Concord and the North Bridge
Securing supplies and sending warnings
Before dawn, messengers rode through the countryside to warn townspeople of the British movement, allowing Concord’s militia to move supplies and hide weapons.
When British units reached Concord, they searched for military stores but found most items removed, diminishing the practical success of the expedition.
Standoff at the bridge
Colonel James Barrett and his men debated whether to engage on the North Bridge, ultimately choosing to confront advancing regulars when smoke appeared near the town.
The exchange at the bridge marked a turning point, as colonial units returned fire and forced the British troops to abandon their hold on Concord.
The Long Retreat to Boston
Snipers along the road
During the return march to Boston, colonial militiamen used fences, stone walls, and buildings to take cover and harass the long column of redcoats.
Regular soldiers formed defensive squares but suffered steadily increasing casualties, demonstrating that disciplined European tactics were ill suited to this kind of terrain and resistance.

The scale of resistance on April 19 1775 convinced colonial leaders to mobilize larger forces and tighten the ring around Boston, laying the groundwork for the prolonged siege.
