The American Revolutionary War began with the “shot heard ’round the world.” At the battles of Lexington and Concord, seventy-three British troops were killed and 200 were wounded or missing in action. The patriot losses were forty-nine dead and forty-six wounded or missing.
In March of 1776, American forces captured Dorchester Heights, which overlooked Boston harbor. They proceeded to enhance their position with artillery captured from Fort Ticonderoga. Outflanked, the British were forced to evacuate Boston and set sail for Halifax, Nova Scotia.
