NEVER FORGET.
You forgot that the battles of Lexington and Concord, MA happened on April 18 - 19, 1775. The first regular U.S. fighting force, the Continental Army, was organized by the Continental Congress on June 14, 1775, to supplement local militias in the American Revolution.
The Battle of Bunker Hill took place on June 17, 1775.
Sorry, Should not have relied on memory, but the meaning is the same.
Thanks for the correction of date.
