Patriots' Day is indeed based on a true story, commemorating actual historical events that marked the beginning of the American Revolutionary War. It is a civic holiday observed in several U.S. states, particularly Massachusetts, Maine, and Wisconsin, and signifies a pivotal moment in the nation's struggle for independence.
Specifically, Patriots' Day commemorates the Battles of Lexington and Concord, which occurred on April 19, 1775. These engagements represented the first military confrontations between the American colonists and British Regulars. The events included the famous "midnight ride" of Paul Revere, William Dawes, and Samuel Prescott, who warned colonial militias of the approaching British forces, leading to the initial skirmishes at Lexington Green and subsequent, more substantial fighting along the British retreat route to Boston. These battles, though relatively small in scale, had immense historical significance as they ignited the full-scale conflict that ultimately led to the formation of the United States.
Thus, the notion that Patriots' Day is a "kisah nyata" (true story) is accurate. The events it commemorates are well-documented historical facts, supported by numerous primary sources from both colonial and British perspectives, making it a commemoration of a foundational and verifiable moment in American history rather than a fictional narrative.
