Final answer:
King George III sent 4,000 redcoats to Boston in 1768 to deal with unrest, and later, on April 14, Thomas Gage deployed 1,000 troops to Lexington and Concord to confront the colonial militia.
Step-by-step explanation:
King George III, driven by a loss of patience with the American colonies and a desire to assert British control, deployed British troops, often referred to as redcoats, to enforce his laws and maintain order. In response to harassments from protesting colonists in Boston, 4,000 redcoats were sent in 1768 to suppress unrest and demonstrate British power. Subsequently, in light of ongoing conflicts and mounting tensions that would eventually lead to the American Revolution, on April 14, Thomas Gage, the commander of the British garrison in Boston, dispatched 1,000 troops to Lexington and then Concord to counteract American preparations for resistance, which included the accumulation of weapons and gunpowder.
