There is evidence to show that Hartsdale played a significant role during the Revolutionary War, some of which still stands today. On October 28, 1776, a Revolutionary War battle was fought alongside the Bronx River, near the site of the current Hartsdale train station. The Odell House (on Ridge Road, built in 1732) served as the headquarters for the French general the Comte de Rochambeau, and is where the count and George Washington are supposed to have formed an alliance leading to the Battle of Yorktown. The house was later named after John Odell, Washington's guide who bought the house in 1785. In 1965, his descendants deeded the house to the Sons of the American Revolution, and today the house is in severe decay, awaiting funds to transform it into a museum.
