Dr. Joseph Warren learned of the British plans and sent Paul Revere to alert John Hancock and Samuel Adams. Paul Revere promised to warn them when the British soldiers started to march. Since he wasn't sure that he would be able to get out of Boston with the message, he made plans to alert people by putting lanterns in the Old North Church steeple.
He would light one lantern if the British were coming by land, and two lanterns if the British were coming by sea. On the evening of April 18 th, the British troops were ferried across the Boston Harbor to start their march on Lexington. Paul Revere hung two lanterns in the church steeple. Then Paul Revere, William Dawes and Dr. Samuel Prescott rode to warn the colonists that the British were coming. Paul Revere rode to Lexington and alerted Samual Adams and John Hancock.
By the time the British soldiers reached Lexington, Samual Adams and John Hancock had escaped.

They had organized a group of militia, called the Minutemen. They were called Minutemen because they needed to be prepared to fight on a minutes notice. When the British soldiers reached Lexington, Captain Jonas Parker and 75 armed Minutemen were there to meet them.
The Minutemen were greatly outnumbered. The British soldiers fired, killing 8 Minutemen and injuring 10 others. Although Paul Revere was captured by British scouts before reaching Concord, other messengers managed to get through and warn the people. While the British soldiers continued on their way to Concord, the men and women of Concord were busy moving the arms and ammunition to new hiding places in surrounding towns. When the soldiers arrived they were only able to destroy part of the supplies. Minute Man Memorial, Concord, Massachusetts (Source: Library of Congress).
