Today, we celebrate George Washington, whose leadership shaped the founding of our Nation and whose faith informed his service. As Commander in Chief of the Continental Army, Washington recognized the essential role of chaplains in sustaining the moral and spiritual strength of the force. In 1775, he supported the Continental Congress’ authorization of military chaplains, affirming their place within the Army from its very beginning.

The U.S. Army Chaplain Corps continues that legacy by supporting the free exercise of religion and offering a steady presence to Soldiers and Families in every generation.

Episode 3: The Times That Try Men’s Souls (July 1776 – January 1777) features the Battle of Long Island (Brooklyn).
The battle began with one of the largest amphibious landings (over 400 vessels supported this operation), on the current site of USAG Fort Hamilton. Its worth watching.

Thirteen colonies unite in rebellion, win their independence, and found the United States. Stream the full documentary from Ken Burns, Sarah Botstein and David Schmidt.

👀👀👀
Right up the road.

On this day 245 years ago, American militiamen captured British Major John Andre at Tarrytown, New York. The night before, Andre had met with the commandant of the American defenses around West Point, Major General Benedict Arnold, to discuss Arnold surrendering the position and defecting to the British. News of Andre's capture reached Arnold only moments before a messenger arrived from General George Washington's entourage, informing Arnold that the commander-in-chief would be arriving at West Point shortly. Arnold fled to Hudson, hijacked a boat, and had himself rowed out to the HMS Vulture, a British sloop-of-war.

Arnold's treachery might have done fatal damage to the American cause as it went off as planned. Instead, it merely did fatal damage to Arnold's reputation. In the United States, he remains a reviled traitor in public memory (unlike other American soldiers who eventually took up arms against their former comrades, Arnold has no public monuments). In Britain, he was widely shunned as an amoral opportunist who fought not out of principle but for mercenary profit. Arnold never set foot in America after he traveled to England in 1781. He died in London on June 14, 1801, at the age of 60. He was buried without military honors.

After the terrorists attack on 9/11/01, soldiers of the U.S. Army at USAG Fort Hamilton were deployed to Ground Zero.

Never forget.
Mourn the loss of those that died.
Sympathize with those injured and sick.
Remember and celebrate the patriotic resurgence that occurred in the aftermath.

Over the decades, many of the soldiers we have encountered at the museum, this event shaped their careers. We can never forget.

NEW ARMY HISTORY MAGAZINE NOW AVAILABLE!!

In the Spring 2025 issue of Army History, we are pleased to present two excellent articles, an in-depth look at a pair of extremely rare and nationally important Army artifacts, and a preview of a unique museum exhibit coming to the Airborne and Special Operations Museum, as well as our usual crop of book reviews.

The first article, by Center of Military History historian Matthew Margis, examines the service of World War I National Guard soldier Francis Webster.

The second article, by Patrick O’Keefe, an active-duty Army major, examines the drive by Wehrmacht units of Army Group South during the initial days of Operation Barbarossa.

The Artifact Spotlight in this issue looks at a pair of pistols once owned by George Washington. Housed at the West Point Museum these pistols were given to Washington just after the winter at Valley Forge and have a very strong provenance. They will feature prominently during the museum’s commemoration of the 250th anniversary of the American Revolution.

This issue’s Museum Feature provides a preview of an upcoming exhibit at the Airborne and Special Operations Museum in Fayetteville, North Carolina. Titled “Surviving the Devil’s Cauldron: The Enduring ‘Swaying Virgin’ of La Gleize,” this exhibit will honor the Monuments, Fine Arts, and Archives officers, also known as the “Monuments Men.”
