Answer+Explanation:
On this day in 1775, British troops march out of Boston on a mission to confiscate the American arsenal at Concord and to capture Patriot leaders Samuel Adams and John Hancock, known to be hiding at Lexington. As the British departed, Boston Patriots Paul Revere and William Dawes set out on horseback from the city to warn Adams and Hancock and rouse the Minutemen.
By 1775, tensions between the American colonies and the British government had approached the breaking point, especially in Massachusetts, where Patriot leaders formed a shadow revolutionary government and trained militias to prepare for armed conflict with the British troops occupying Boston. In the spring of 1775, General Thomas Gage, the British governor of Massachusetts, received instructions from Great Britain to seize all stores of weapons and gunpowder accessible to the American insurgents. On April 18, he ordered British troops to march against Concord and Lexington.
The Boston Patriots had been preparing for such a British military action for some time, and, upon learning of the British plan, Revere and Dawes set off across the Massachusetts countryside. They took separate routes in case one of them was captured: Dawes left the city via the Boston Neck peninsula and Revere crossed the Charles River to Charlestown by boat. As the two couriers made their way, Patriots in Charlestown waited for a signal from Boston informing them of the British troop movement. As previously agreed, one lantern would be hung in the steeple of Boston’s Old North Church, the highest point in the city, if the British were marching out of the city by Boston Neck, and two lanterns would be hung if they were crossing the Charles River to Cambridge. Two lanterns were hung, and the armed Patriots set out for Lexington and Concord accordingly. Along the way, Revere and Dawes roused hundreds of Minutemen, who armed themselves and set out to oppose the British.
