Massachusetts Investigates the Events of April 19, 1775
In the aftermath of the events of April 19, 1775, the Massachusetts Provincial Congress ordered local officials to interview witnesses and participants. Congress wanted to establish a key concept — the British fired first. If that could be established, it would place the fault for the action on General Thomas Gage, Lieutenant John Pitcairn, and Lieutenant Colonel Francis Smith.
The American Revolutionary War Begins — The Battles of Lexington and Concord
The events of April 19, 1775 — the day the American Revolutionary War started — began well before that day. However, the immediate sequence of events that led to hostilities started with the Boston Tea Party. Parliament responded to the protest by passing the Intolerable Acts, which significantly increased the tension between British officials and the people of Massachusetts.
Tensions Rise Between British Officials and the People of Massachusetts
General Thomas Gage, the Royal Governor of Massachusetts, increased his control over the province by removing military supplies from public storehouses and building defensive works in Boston. The people of Massachusetts, spurred on by political leaders in Boston who were associated with the Sons of Liberty, responded by setting up the Massachusetts Provincial Congress and preparing for hostilities.

British Spies Uncover Military Supplies Hidden in Concord
Gage was notified of the Massachusetts preparations by a spy, Dr. Benjamin Church. In turn, Gage asked Parliament to send for reinforcements. He also sent spies out into the countryside to map roads and gather intelligence. Around March 20, 1775, two British spies informed Gage there were cannons, artillery, and provisions hidden in Concord, Massachusetts.
The Midnight Riders
On the night of April 18, 1775, Gage issued orders to Lieutenant Colonel Francis Smith to lead British forces to Concord. The goal of Smith’s mission was to find and destroy weapons and supplies hidden there by the Massachusetts Militia. The Patriot spy network in Boston uncovered the plan and Dr. Joseph Warren sent express riders Paul Revere and William Dawes to Lexington and Concord to warn people.
Captain John Parker Assembles the Lexington Militia
Revere arrived in Lexington and warned Samuel Adams and John Hancock the British were on their way. The alarm was raised and Captain John Parker assembled the Lexington Militia on Lexington Common. The British advance force, under the command of Lieutenant John Pitcairn, arrived in Lexington early in the morning and found Parker and roughly 75 men blocking the road.
British Forces Attack Parker and His Men on Lexington Common
Pitcairn ordered Parker and his men to disperse and leave their weapons. Parker ordered his men to leave, but as they did, they took their guns with them. Within seconds, a shot was fired and then both sides opened fire. By the time Pitcairn restored order, eight Americans had been killed, and 10 more were wounded. The British formed their ranks and continued the march to Concord, to complete their mission.
Concord and the March Back to Boston
At Concord, the British were able to find and destroy some of the supplies but were engaged by gathering militia forces at the Old North Bridge where the “Shot Heard ‘Round the World” was fired. The Massachusetts Militia followed the British all the way back to Boston, along the way, Parker’s men attacked just outside of Lexington. Militia forces continued to join the fight, as did William Heath and Joseph Warren, and harassed the British as they moved into Menotomy. The militia ended its pursuit at Menotomy. However, the militia gathered around Boston, effectively laying siege to the city and trapping British forces.
