One of the oldest surviving U.S. Army buildings in America is the Hessian Powder Magazine in Carlisle, Pennsylvania. This sturdy limestone structure was built during the darkest days of the American Revolution to store the gunpowder and ammunition that helped sustain George Washington’s army. But who built it? And why has it long been known as the “Hessian” Powder Magazine?

Join us for a special America 250 program featuring a screening of the new 40-minute documentary The Hessian Powder Magazine, followed by a live conversation with historian Jack Leighow of the U.S. Army Heritage & Education Center and Army University, who helped lead the years-long research behind the film.

Drawing on newly uncovered documents, architectural analysis, ground-penetrating radar, and archaeological excavations, the documentary follows the remarkable effort to solve a centuries-old historical puzzle. The investigation confirms that the building is indeed the Revolutionary War powder magazine constructed in 1777 as part of the sprawling military depot at Carlisle, one of the Continental Army’s most important centers for manufacturing weapons, ammunition, and military supplies. It also reveals compelling evidence that Hessian prisoners captured at Trenton likely helped build the magazine, giving new meaning to a name that had long been dismissed as little more than local legend.

The story illuminates the enormous logistical effort behind American independence, the workshops, foundries, carpenters, blacksmiths, laborers, and military planners who supplied Washington’s army when victory depended as much on production as battlefield success. It also reminds us that history is never finished. Even after 250 years, archaeology, archival research, and careful scholarship continue to reshape what we know about the Revolution.

Following the film, Jack Leighow will discuss the investigation, answer questions, and explain how this remarkable survivor of the Revolutionary War is helping us better understand the nation’s founding as America approaches its 250th anniversary.

Join the Veterans Breakfast Club for a remarkable conversation with William S. Reeder Jr., the last U.S. Army soldier taken prisoner during the Vietnam War and author of Through the Valley: My Captivity in Vietnam.

In 1972, then-Captain Reeder was flying Cobra gunship missions in support of South Vietnamese forces near the besieged Special Forces camp at Ben Het, close to the Cambodian border. During an intense battle, his helicopter was shot down. After evading capture for three days, he was taken prisoner by North Vietnamese forces.

What followed was an extraordinary ordeal. Reeder spent weeks confined in jungle cages before enduring a brutal forced march along the Ho Chi Minh Trail. Seven men in his group of twenty-seven POWs died during the journey. Eventually imprisoned in Hanoi, he spent nearly a year in captivity before returning home during Operation Homecoming in 1973.

Reeder’s memoir, Through the Valley, vividly recounts not only the horrors of captivity but also the bonds among prisoners, the strength drawn from family and country, and the determination to survive under unimaginable conditions.

A decorated Army aviator, Reeder flew dangerous reconnaissance and attack missions throughout Southeast Asia, including classified operations over Laos, Cambodia, and North Vietnam. His service earned him numerous decorations, including the Silver Star, Distinguished Flying Cross, Bronze Star, Purple Heart, and Prisoner of War Medal.

During this live conversation, Reeder will reflect on his service and, as always, we’ll leave plenty of time for audience questions and conversation.
