“Let it begin here”.
At about 5 a.m., 700 British troops, on a mission to capture Patriot leaders and seize a Patriot arsenal, march into Lexington to find 77 armed minutemen under Captain John Parker waiting for them on the town’s common green. British Major John Pitcairn ordered the outnumbered Patriots to disperse, and after a moment’s hesitation the Americans began to drift off the green. Suddenly, the “shot heard around the world” was fired from an undetermined gun, and a cloud of musket smoke soon covered the green. When the brief Battle of Lexington ended, eight Americans lay dead or dying and 10 others were wounded. Only one British soldier was injured, but the American Revolution had begun.
By 1775, tensions between the American colonies and the British government 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 England to seize all stores of weapons and gunpowder accessible to the American insurgents. On April 18, he ordered British troops to march against the Patriot arsenal at Concord and capture Patriot leaders Samuel Adams and John Hancock, known to be hiding at Lexington.
