MERCUTIO: Why, is not this better now than groaning for love?
now art thou sociable, now art thou Romeo; now art
thou what thou art, by art as well as by nature:
for this drivelling love is like a great natural,
that runs lolling up and down to hide his bauble in a hole.
This is the line...I think
I don't exactly have a poem to go off of here, but what happened was that Paul Revere saw the signal lanterns under Christ church and night. This was a signal that the British were there and ready for war. Then he got on his horse, and went all through town screaming "The British Are Coming!" which woke everyone up, and they saw the lantern as well. Paul's warning gave the colonists and the militia men time to prepare for the fight. Basically saving them.
Hope This helped :)
