# Fort Myer

fort myer is the previous name used for a U.S. Army post next to Arlington National Cemetery in Arlington County, Virginia, and across the Potomac River from Washington, D.C. Founded during the American Civil War as Fort Cass and Fort Whipple, the post merged in 2005 with the neighboring Marine Corps installation, Henderson Hall, and is today named Joint Base Myer–Henderson Hall. == History == In 1861, the land that fort myer would eventually occupy was part of the Arlington estate, which Mary Anna Custis Lee, the wife of Robert E. Lee, owned and at which Lee resided when not stationed elsewhere (see Arlington House, The Robert E. Lee Memorial). When the Civil War began, the Commonwealth of Virginia seceded from the United States, Lee resigned his commission, and he and his wife left the estate.
