SPONSOR Washington-Rochambeau National Historic Trail 
DETAILS Dr. de Rode’s lecture will discuss the preparatory phase of the Yorktown Campaign. Focus will be placed on understudied French officers, such as Chastellux, Vioménil and Montesquieu, who will illustrate the critical details of the exact interplay between the French and American forces during the time of the preparation for the Yorktown campaign, during the winter of 1780 and 1781. This period has been almost entirely overlooked by historians but is an essential step in the victory of Yorktown. 
ABOUT THE PRESENTER Dr. Iris de Rode is specialized in the French participation in the American Revolution, and more broadly in the history of the Atlantic Revolutions. Iris earned her doctoral degree in November 2019. Her dissertation will be published in French in the autumn of 2021 and she is currently working on the publication of an adaptation of this dissertation in English to be published in 2023 with the University of Virginia Press.

SPONSORS RW250, Warner Library and The Historical Society, Inc. Serving Sleepy Hollow & Tarrytown  and the Hudson River Patriots Chapter NSDAR
DETAILS During the Revolutionary War, Tarrytown played a dramatic and crucial role in the achievement of American independence; yet, revolutionary events in Tarrytown and Westchester, once celebrated and known to both locals and Americans across the nation, have lapsed into obscurity or become the stuff of legend. This illustrated lecture provides an overview of important events and locations in the area around Tarrytown during the Revolutionary War and examines the importance of the era’s legacy on its historical development, on regional identity, and on the formation of national character.
Presenter Erik Weiselberg, Ph.D. also serves as the Village Historian in Irvington, New York, teaches social studies at Irvington High School, Irvington, New York, and is the recipient of the 2020 Hudson River Patriots Chapter, NSDAR and 2020 NYS DAR Outstanding Teacher of American History award.
