While Paul Revere most certainly did not yell "the Americans are COming", while Americans were still in bed, ringing a bell and shooting his rifle warning the British that they will not take away our 2nd ammendment rights regardind our guns...
He did warn others to spread the warning that the British Fleet were near the harbor.
The midnight ride of Paul Revere was made by Isreal Bissel who rode nearly 400 miles spreading the word the British warships had arrived.
