Two hundred forty years ago today, the “shot heard around the world” signaled the start of the American Revolutionary War. As described on History.com, 

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.

The next few years would be difficult and trying, but eventually, the brave colonists would prevail. I shall ever be grateful for those who redeemed this great nation by shedding their precious blood in our behalf. (Doctrine & Covenants 101:80)
