Evacuation of Boston March 18, 1776
The Americans found the works deserted, entered in triumph with drums beating and colours flying. Putmann took command of the city and the flag of thirteen stripes, the standard of the Union, floated above all the forts. Among the accidents of the Bombardement was the bursting of Putnam's vaunted mortar, the Congress* March 9. The mortar was fixed in a bed; old Putnam mounted it, dashed on it a bottle of rum, and gave it the name of Congress.
