Who fired the first shot on Lexington Green on the morning of April 19, 1775, remains in dispute. Both the British regulars and the American rebels vehemently denied that it came from their side. What is agreed on is that after that first shot was heard, there was immediately sporadic and then volley fire from the British regulars. In June, there was the catastrophic Battle of Bunker Hill. While the result was indecisive, it was a self-proclaimed British victory at a staggering cost.
