Joseph Warren’s life as a Patriot was rather brief (in fact his life overall was relatively short), but it was quite important to the cause. Warren was part of the committee that investigated the Boston Massacre, he sent Paul Revere on his midnight ride (just go with it for now), he wrote a song called “Free America,” which was based on a British melody called “The British Grenadiers”, he fought at Lexington and Concord, and he died at Bunker Hill.
