When President Abraham Lincoln first proclaimed Thanksgiving a national holiday, little did he know he was spelling the beginning of the end to the prominence of the original patriotic celebration held during the last week of November: Evacuation Day.

In November 1863, Lincoln issued an order thanking God for harvest blessings, and by the 1940s, Congress had declared the 11th month of the calendar year’s fourth Thursday to be Thanksgiving Day.

That commemoration, though, combined with the gradual move toward détente with what is now the U.S.’ strongest ally – Great Britain – displaced the day Americans celebrated the last of the Redcoats fleeing their land.

Following the Declaration of Independence in Philadelphia in 1776, New York City, just 99 miles to the northeast, remained a British stronghold until the end of the Revolutionary War.

Captured Continentals were held aboard prison ships in New York Harbor and British political activity in the West was anchored in the Big Apple, according to the Department of Veterans Affairs.

However, that all came crashing down on the crown after the Treaty of Paris was signed, and new “Americans” eagerly saw the British out of their hard-won home on Nov. 25, 1783.

In their haste to flee the U.S., the British took time to grease flagpoles that still flew the Union Jack. One prominent post was at Bennett Park – on present-day West 183 Street near the northern tip of Manhattan.

Undeterred, Sgt. John van Arsdale, a Revolution veteran, cobbled together cleats that allowed him to climb the slick pole and tear down the then-enemy flag. Van Arsdale replaced it with the Stars and Stripes – and without today’s skyscrapers in the way, the change of colors at the island’s highest point could be seen farther downtown.

In the harbor, a final blast from a British warship aimed for Staten Island, but missed a crowd that had assembled to watch the 6,000-man military begin its journey back across the Atlantic to King George III.

Later that day, future President George Washington and New York Gov. George Clinton – who had negotiated “evacuation” with England’s Canadian Gov. Sir Guy Carleton – led a military march down Broadway through throngs of revelers to what would today be the Wall Street financial district at the other end of Manhattan.

Clinton hosted Washington for dinner and a “Farewell Toast” at nearby Fraunces’ Tavern, which houses a museum dedicated to the original U.S. holiday. Samuel Fraunces, who owned the watering hole, provided food and reportedly intelligence to the Continental Army.

Washington convened at Fraunces’ just over a week later to announce his leave from the Army, surrounded by Clinton and other top Revolutionary figures like German-born Gen. Friedrich von Steuben – whom New York’s Oktoberfest-styled parade officially honors.

“With a heart full of love and gratitude, I now take leave of you. I most devoutly wish that your latter days may be as prosperous and happy, as your former ones have been glorious and honorable,” Washington said.

Before Lincoln – and later Congress – normalized Thanksgiving as the mass family affair it has become, Evacuation Day was more prominent than both its successor and Independence Day, according to several sources, including Untapped New York.

Nov. 25 was a school holiday in the 19th century and people re-created van Arsdale’s climb up the Bennett Park flagpole. Formal dinners were held at the Plaza Hotel and other upscale institutions for many years, according to the outlet.

An official parade reminiscent of today’s Macy’s Thanksgiving Parade was held every year in New York until the 1910s.

As diplomatic relations with the United Kingdom warmed heading into the 20th century and the U.S. alliance with London during the World Wars proved crucial, celebrating Evacuation Day became less and less prominent.

Into the 2010s, however, commemorative flag-raisings have been sporadically held at Bowling Green, the southern endpoint of Broadway. On the original Evacuation Day, Washington’s dinner at Fraunces Tavern was preceded by the new U.S. Army marching down the iconic avenue to formally take back New York.

Thirteen toasts – marking the number of United States – were raised at Fraunces, each one spelling out the new government’s hope for the new nation or giving thanks to those who helped it come to be. 

An aide to Washington wrote them down for posterity, and the Sons of the American Revolution recite them at an annual dinner, according to the tavern’s museum site.

“To the United States of America,” the first toast went. The second honored King Louis XVI, whose French Army was crucial in America’s victory.

“To the vindicators of the rights of mankind in every quarter of the globe,” read another. “May a close union of the states guard the temple they have erected to liberty.”

The 13th offered a warning to any other country that might ever seek to invade the new U.S.:

“May the remembrance of this day be a lesson to princes.”
