The Shot Heard Round the World: Lexington and the Start of Revolution

These depositions are among the most important primary sources for teaching the Battle of Lexington, and they reward careful, critical reading. Collected by the Massachusetts Provincial Congress in the days immediately following April 19, the depositions served an explicit political purpose: to establish before the world that British troops fired first on peaceful colonists. This context does not make them unreliable — the deponents were under oath and describing events they personally witnessed — but it means students should consider how political urgency shaped what was recorded and how. Guide students to notice what the depositions share in common: the militia was dispersing when firing began, the British advanced in battle formation, the colonists did not intend to engage. Then push students to notice what varies: the sequence of events, the number of shots, whether orders were given. This is where genuine historical thinking begins. Contradictions between honest eyewitness accounts are not evidence of deception — they are evidence of the chaos of lived experience. Use these documents to build students' capacity for holding ambiguity and evaluating evidence on its own terms.

Lieutenant Barker's diary is a gift for teaching source analysis because it complicates the simple binary of "British account vs. colonial account." Barker was critical of his own commanders — he thought the expedition was poorly planned and badly executed — which gives his account a credibility that official reports lack. A soldier complaining in his private diary about his superiors is unlikely to be crafting propaganda. Guide students to consider the difference between public and private sources. The colonial depositions were created for publication and political persuasion. Barker's diary was never intended for an audience. Ask students: does this make it more reliable? Less reliable? In what ways? Students often assume that "the other side" is simply lying. Barker's diary helps them move beyond that simplistic framework toward a more sophisticated understanding of perspective, context, and the limits of any single account. This is exactly the kind of source that builds genuine historical thinking skills rather than reinforcing comfortable narratives.

Visual primary sources offer a powerful entry point for students who struggle with dense written texts. The Doolittle engravings are especially valuable because they were created by someone who actually visited the sites and interviewed witnesses, yet they are clearly constructed arguments about what happened. Have students "read" the images like texts: What is in the foreground? What is emphasized? Where are the British soldiers relative to the militia? These choices tell a story. Doolittle was a Connecticut patriot — his sympathies are clear in how he composed the scenes. This makes the engravings excellent for teaching that even "documentary" images reflect a point of view. Pair them with the written sources for a multimedia analysis that builds visual literacy alongside textual analysis skills.
