There were rumors that the patriots had been smuggling weapons into their possession in order to possibly prepare for a physical revolt against British troops. The Red coat Army was given orders to go and confiscate Colonial weapons that were smuggled in for the possible uprising.
Paul Revere spoke with fellow Patriots about the British' arrival. They agreed that 1 lantern would be lit if the British came by land, and two lanterns would be lit if they came by sea; if the Red Coats came by land, the colonists would have more time to prepare. Robert Newman would be the patriot to light the lantern.
After receiving orders to confiscate the smuggled weapons of the Patriot army, the Red Coat army marched toward Lexington and Concord and followed Colonel Smith into battle. The Patriot Army was able to set up for an ambush against the Red Coats.
On April 19, 1775, "The Shot heard 'round the world" was fired just after dawn. The British Army had made it's way to Concord and was surprised by the Colonial Army. The Patriots were able to prepare for the Red Coat Army's arrival with barriers and weapons. The first shot of the battle, and of the American Revolution, was fired by the Colonists. It was "heard 'round the world" because every other power had noticed the British colonies were militantly revolting.
After the 'Shot heard round the world' was fired, the Red Coat Army and Patriot Militia met up in Lexington and engaged in a gory battle. The Red Coat Army was faced with a rather tough opponent here. They had seemingly underestimated the Colonists, assuming they were just a bunch of farmers, not an actual, respectable militant group. The British Army continued to fight in hopes that they would still find the weapons.
After the fighting, almost 100 British soldiers were killed along with nearly 200 wounded, whereas less than 100 Colonial troops were killed. The British had begun to retreat back to Boston after about 4 hours of fighting. This battle displayed the determination and seriousness of the Patriot Army; they earned some respect from their opponent, and they sparked the Revolutionary War.
