31 Days of Boston — Day 19
On April 18, 1775, lanterns, riders, church towers, boats, and alarm networks carried the news that British troops were moving.
Boston on the night of April 18, 1775, was a town under military occupation—and a town filled with watchers.
British troops prepared to cross the Charles River and move toward Concord, where colonial military supplies were believed to be stored. Patriot intelligence networks detected the movement.
Lanterns displayed from the steeple of Christ Church, now known as Old North Church, helped signal the route. Paul Revere crossed the river and rode into the countryside. William Dawes and other messengers also spread the alarm.
The famous story has been polished by poetry, but the underlying achievement is more impressive than the legend. This was a decentralized communications network operating without telephones, radios, or engines. Riders, bells, guns, drums, and local committees moved information from community to community.
By dawn, British regulars would face armed militia at Lexington. Boston’s political rebellion had become war.
