Imagine you're at the Green Dragon Tavern in the 1700s. In the corner, Samuel Adams and Paul Revere are arguing about the latest political pamphlets over a flagon of ale. The whole city of Boston is abuzz with jostling voices and new ideas...

But how much do you really know about this revolutionary period that birthed the United States and changed the world?

While you might know lots about the Boston Tea Party or the Declaration of Independence, here are 10 lesser-known stories, hidden figures, and moments that made the nation.

Did you know the Continental Congress actually voted for independence in 1776 on July 2nd not July 4th? Founding Father John Adams predicted that the 2nd would be celebrated by future generations with "pomp and parade." However, because the formal Declaration document was approved on the 4th, that date became the one etched into history.

To keep secrets during the war, a Patriot spy network established by George Washington, called the Culper Ring, would use invisible ink to write hidden messages. One spy would write a mundane letter, then hide the real intel between the lines using a chemical that only became visible when treated with a special substance.

During the brutal winter at Valley Forge, Polly Cooper, an Oneida woman, led a group hundreds of miles to deliver white corn to the starving Continental Army. She accepted only a shawl as a token of gratitude, refusing any other payment for her vital service.

Smallpox, not British bullets, posed one of the greatest threats to Washington's troops during the war. A massive outbreak prompted Washington's secret order for the first large-scale immunization program in American history, preventing his army from disappearing before battle.

On the 5 March 1770, British soldiers fired into a crowd of Bostonians, killing multiple people including sailor Crispus Attucks. This caused a serious outcry and became known as the ‘Boston Massacre’. Attucks became a martyr for the revolutionary cause.

We speak of the 13 colonies, but the revolutionaries desperately hoped for 14. In 1775, the Continental Army launched an invasion of Quebec, hoping to spark a pro-independence uprising in Canada. However, the campaign was a frostbitten failure and Canada remained a loyal British stronghold.

The famous warning, "The British are coming!", was probably never said. In 1775, colonists still identified as British and the soldiers of the British Army were known as Regulars. So Paul Revere likely actually said, "The Regulars are coming out."

The war saw the birth of submarine warfare. The American Turtle, a one-man, hand-cranked wooden submersible, attempted to attach an explosive charge to a British warship in New York Harbor. Though the mission failed to sink a ship, it remains a testament to the inventive spirit of 1776.

During the war, British prison ships, such as the notorious HMS Jersey, were floating graveyards. Disease and starvation claimed the lives of approximately 11,000 prisoners. Which was nearly double the number of those killed in battle throughout the entire war.

While the revolution began in Massachusetts, it ended as a global struggle. It was not just a fight between Great Britain and its colonies. The survival of the young United States depended on a complex web of international alliances, including France, the Netherlands, and Spain.

Sowing the seeds of a rebellion had to be done in secret, and where better to meet up with fellow revolutionaries to discuss protests, battles, and building a new nation than the local tavern? From New York to Virginia, take a virtual visit to these iconic sites that still exist today.

This tavern is named after Samuel Fraunces, the restaurateur who bought the building in 1762 and turned it into a site that would become an integral meeting point for Patriots in New York. Famously George Washington celebrated the final evacuation of the British Army from American shores in 1783 here.

This was the local haunt for famous Boston Patriots Paul Revere and prominent Founding Father John Hancock. It is even known that the plans for the invasion of Lexington and Concord that kick-started the Revolutionary War were discussed in this very tavern.

The second ever President of the United States, John Adams, once said this was “the most genteel tavern in America.” Today you can visit the tavern and step back to the time of the revolution with costumed waiters and a Colonial-era menu.
