This month, we commemorate the 250th anniversary of the Battles of Lexington and Concord, the “shot heard round the world” that ignited the Revolutionary War.

To help us investigate, we’re revisiting our conversation from Episode 350 with Pulitzer Prize-winning historian Stacy Schiff, author of The Revolutionary: Samuel Adams.
