Washington at Dey Mansion in 1780: A Lecture by Tom Dempsey
Local historian Tom Dempsey returns to Dey Mansion to share the history of daily events at the headquarters in July 1780. In his presentation, Tom will discuss how events were shaped by the anticipated arrival of the French forces. The General Orders and correspondence from that time reflect a growing resolve by Washington to launch an attack on New York, despite troubling reports of British naval superiority. As the month progressed, Washington learned that the British had their own menacing plans, ultimately forcing the Continental Army to leave Preakness.

Dey Mansion is proud to welcome Dr. Iris de Rode for a special lecture on the historic 1780 meeting between General George Washington and the Marquis de Chastellux, which took place right here at Dey Mansion.
As a major general in Rochambeau’s expeditionary force, Chastellux played a pivotal role in logistics and strategic planning, and—most importantly—served as the key liaison between General Rochambeau and General Washington. Throughout the campaign, Washington and Chastellux developed a deep friendship that strengthened the Franco-American alliance and helped shape the course of the Revolutionary War.
Drawing from Chastellux’s long-forgotten private papers—rediscovered by Dr. de Rode in the Chastellux family château in Burgundy—this lecture will vividly bring their transformative encounter to life and offer fresh insights into the human bonds at the heart of this historic alliance.

In Reduced Circumstances: Loyalist Women and British Government Assistance, 1779-1783
The American Revolution involved every man, woman and child in America, directly or otherwise. While some women followed their husband’s or family’s allegiance in the conflict, others viewed their own opinions. Those retaining an allegiance to the British faced a wide range of experiences, ranging from mob violence to abject poverty and homelessness. Many lost family members. Others accompanied their husbands on campaign while some actively supported the crown in the secret service. We will examine the circumstances and tribulations of many of these Loyalist women and what became of them once the war ended.

Loyalist Lecture by Todd Braisted (Summer Kitchen)
The Plan to Kidnap George Washington
The winter of 1779-1780 was referred to as “the severest in human memory.” The main British Army under Sir Henry Clinton was laying siege to Charleston, South Carolina. George Washington’s main army lay hutted at Jockey Hollow, about five miles northwest of Morristown, where Washington himself took quarters at the Ford Mansion, with but a small detachment of his Life Guard. Morristown’s distance from British-occupied New York City and the severity of the weather ensured his safety better than a large army surrounding him could. Or so he thought. Join us as we examine the British plot to spirit the Father of our Country into British captivity and perhaps bring the Revolutionary War to a shocking end.
