The Battles of Lexington and Concord

A comprehensive Timeline of the Battles of Lexington and Concord, including the causes of the battles and events that unfolded on April 18–19, 1775. The battles were fought between the Massachusetts Militia and British forces on April 19, 1775. The battles followed the Midnight Rides and the Lexington Alarm, which alerted the countryside to British troops marching to Concord. The situation escalated when the British fired on the Lexington Militia, starting the American Revolutionary War.

The Lexington Alarm — The Midnight Riders

On the night of April 18, Joseph Warren sent two Express Riders, Paul Revere and William Dawes, to spread the news that the British were marching to Lexington and Concord. They took separate routes out of Boston and raised the alarm along the way. They reached Lexington safely and were joined by Samuel Prescott as they made their way to Concord. They were apprehended by British troops. Revere was seized while Dawes and Prescott escaped. Prescott was the only rider who reached Concord.

Paul Revere’s Midnight Ride is one of the most famous events in American History. Ralph Waldo Emerson memorialized it in his 1861 poem, “Paul Revere’s Ride.” The poem is partially based on Revere’s testimony regarding the events of the night of April 18–19, 1775.

In 1798, Revere wrote a letter to Jeremy Belknap in which he recalled the Lexington Alarm and his Midnight Ride and laid out his suspicions regarding the traitor, Dr. Benjamin Church.

The Lexington Alarm — Massachusetts Towns

The following militia companies mustered but did not engage the British.

Battle of Lexington

The Battle of Lexington occurred on the morning of April 19, 1775, in Lexington, Massachusetts. During the incident, British troops intentionally fired on the colonial militia that had assembled on Lexington Common.

Battle of Concord

The Battle of Concord was fought between the Massachusetts Militia and Great Britain on April 19, 1775, the first day of the American Revolutionary War. Following the Battle of Lexington, a British expedition marched to Concord and destroyed military supplies. After a fire started in the town, the Massachusetts Militia engaged the British at the North Bridge and fired the “Shot Heard ‘Round the World.” The British were forced to withdraw and marched back to Boston with American forces in pursuit.

Parker’s Revenge

Parker’s Revenge occurred on April 19, 1775, near Lexington, Massachusetts, west of Boston. It was one of the opening battles of the American Revolution, the second at Lexington that day. The Lexington Militia attacked the British as they marched by and followed them back to Boston, where the Lexington men joined in the Siege of Boston.

Siege of Boston

The Siege of Boston was conducted by American militia forces against the British, who were trapped in the city following the Battles of Lexington and Concord. It lasted for 11 months and included the Battle of Bunker Hill and the formation of the Continental Army. The siege ended when Americans occupied Dorchester Heights, forcing the British to evacuate. This also ended the British occupation of Boston, which had started in 1768.
