Who hung the warning lanterns?

The warning lanterns were hung by Paul Revere, a patriot and silversmith, during his famous midnight ride on April 18, 1775. He used the lanterns as a signal system to alert the American colonists about the British troops' movements—one lantern if they were coming by land and two if by sea. This act was part of the larger effort to prepare for the Battles of Lexington and Concord, marking the start of the American Revolutionary War.
