Their actions that day became the spark that lead to the Revolution.
I always take this day to remember one man. Samuel Whittemore, State Hero of Massachusetts. Born in 1696. Served in a Massachusetts Regiment in King George's War in the 1740s. On the 19th of April, 1775, he was 80 years old.
Upon hearing of the events of the day, he loaded his muskets and two French pistols he had kept from his prior service and went to intercept the retreating British. He shot one with the musket and another with the first pistol, with decisive result. He wounded a third with the last pistol. Then he drew a sword and attacked.
The rest of the British detachment shot him in the face, bayoneted him several times, and left him for dead. When he was found, he was trying to reload. He survived this, lived another 18 years, dying at the age of 98, a citizen of the United States.
"Stand your ground. Don't fire unless fired upon, but if they mean to have a war let it begin here." --Captain John Paarker, on Lexington Green, April 19, 1775.
