It gives me great pleasure thank the many people who assisted me in the preparation of this report. First of all thanks are due to the Florence Gould Foundation for funding the research, to the Hudson River Valley Greenway for administering the grant, and to project director Dr. James M. Johnson, Colonel, US Army (Ret.), for his assistance and guidance.

Many a citizen of the State of New York has helped by various ways and means. Ms Tema Harnik, Director of the Lower Hudson Conference welcomed me to Elmsford, and gave me the opportunity to present my findings at a "Symposium on Interpreting American Revolutionary Sites & Stories" on 25 May 2001. Ms Katie Hite, director of the Westchester County Historical Society and Archives and its librarian Ms Elizabeth Fuller gave me access to their treasures, especially the MacDonald Papers; Ms Sarah Henrich, Executive Director, Historical Society of Rockland County, did the same on the other side of the Hudson. In Waterford, Peter D. Shaver and John A. Bonafide, Historic Preservation Program Analysts for Westchester and Rockland Counties in the New York State Office of Parks, Recreation, and Historic Preservation gave generously of their time and advice. Dr. Joseph Meany, Jr., Office of the State Historian at the New York State Museum, provided information on earlier attempts at marking the Washington-Rochambeau Route through the State, and Albert D. McJoynt drew the maps. Robert Stackpole, Frank Jazzo, Peter Q. Eschweiler, and Richard Presser were invaluable for researching the Franco-American camp at Philipsburg and the Odell House; Ms Lynn Roessler and John Curran, Peekskill City Historian, John Martino of Lancaster, Pennsylvania, Mike Clark of the New Windsor Cantonment and Thomas Flynn, Historian for the Borough of Yonkers, provided valuable images and information. Drs. Allan Gilbert (Anthropology) and Roger Wines (History) of Fordham University pointed out the Corsa/Rose Hill Manor archeological site to me. I was welcomed by Don Loprieno, Site Manager of the Stony Point Battlefield State Historic Site, Carol Hagglund, Director of Philipsburg Manor, and Laura Correo, Director, Van Cortlandt House Museum. Mr. Judd Levin generously shared his research on the Van Cortland House with me while Dr. Lloyd Ultan, Bronx Borough Historian, answered my questions on the Grand Reconnaissance in the Bronx. In driving most of the route with me, Ms Nancy Bayer of Garrison, also traced the journey her ancestor William de Deux-Ponts had taken 220 years earlier. In France, M. le comte Jacques de Trentinian, a descendant of an officer in Lauzun's Legion, answered many inquiries; so did M. Gérard-Antoine Massoni, an expert on Lauzun's Legion. John W. Shannahan, Historic Preservation Officer for the State of Connecticut graciously granted permission to re-use, in updated form, parts of the historical background essay from my report on the Washington-Rochambeau Revolutionary Route for the State of Connecticut. I would be greatly amiss if I would not thank my good friend and colleague Dr. Samuel F. Scott who generously shared his vast knowledge of Rochambeau's troops, as well as the late Donald Brandt and Dr. Philip J. Handrick, who have been interpreting the Royal Deux-Ponts since 1976 and who put their files at my disposal. The generous assistance provided by David P. Jensen, director of Hope College's VanWylen Library, and by Ms Helen Einberger, head of the Inter-Library Loan Department, greatly facilitated the completion of this report.

Last but by far not least I would like to thank my wife Barbara and my children Mary, Sebastian, and Hannah for doing without me for three long weeks in the fall of 2000, and for their patience during the time I spent in front of the computer. Thank you all.
