Why did the Concord skirmish happen?

Answer 1

In 1775, on what turned out to be the first day of the American War for Independence, the Concord "skirmish" happened mainly for three reasons. First, word had spread quickly of the one-sided battle at Lexington earlier in the day, and colonists were eager to make a better showing against the British troops. Second, patriotic fever was running very high in New England, and the British march to Concord came as a challenge that the local patriots were no longer willing (or perhaps even able) to ignore. Third, a large number of patriots had gathered at Concord, and the odds of a favorable battle were in their favor.
