3.2: The Battle of Lexington

Difficulty Level: At Grade Created by: CK-12
Turn In

After the passage of the Stamp Act, tensions between the colonists and the British government continued to rise, and the colonists began to organize militias. On April 19, 1775, British troops marched from Boston to the nearby towns Lexington and Concord to arrest the militia’s leaders, John Hancock and Sam Adams, and to confiscate their weapons. The militias learned in advanced that the British were coming, and about 70 militiamen, also called minutemen, assembled before dawn on the central green of the town of Lexington. As dawn was breaking, a shot rang out which set off the first battle of the American Revolution. But who fired the shot? The historical sources disagree. Read the documents below and attempt to determine which side fired first. Then analyze the two paintings of the battle and decide which is a more accurate representation of the battle.

A sample exploration of these documents can be viewed in the video at http://historicalthinkingmatters.org/why/.

Diary of John Barker

Source: Entry for April 19th, 1775, from the diary of Lieutenant John Barker, an officer in the British army.

19th. At 2 o’clock we began our march by wading through a very long ford up to our middles. After going a few miles we took three of four people who were going off to give intelligence. About 5miles on this side of a town called Lexington, which lay in our road, we heard there were some hundreds of people collected together intending to oppose us. At 5 o’clock we arrived there and saw a number of people, I believe between 200 and 300, formed in a common in the middle of the town. We still continued advancing, keeping prepared against an attack though without intending to attack them. But on our coming near them they fired one or two shots, upon which our men without any orders, rushed in upon them, fired and put them to flight. We then formed on the Common, but with some difficulty, the men were so wild they could hear no orders; we waited a considerable time there, and at length proceeded on our way to Concord.

Account of the Battle of Lexington – Nathaniel Mullikan

Source: Sworn by 34 minutemen on April 25 before three Justices of the Peace.

We Nathaniel Mulliken, Philip Russell, (Followed by the names of 32 other men present on Lexington Green on April 19, 1775)... All of lawful age, and inhabitants of Lexington in the County of Middlesex... do testify and declare, that on the nineteenth of April.... about five o’clock in the morning, hearing our drum beat, we proceeded towards the Green, and soon found that a large body of troops were marching towards us. Some of our company were coming to the Green, and others had reached it, at which time, the company began to disperse. While our backs were turned on the British troops, we were fired on by them, and a number of our men were instantly killed and wounded, not a gun was fired by any person in our company on the British soldiers to our knowledge before they fired on us, and continued firing until we had all made our escape.

Lexington, April 25, 1775.
