Gallagher, in Lee and His Army in Confederate History (Chapel Hill: University of North Carolina Press, 2001, ISBN 978-0-8078-2631-7), p. 173, wrote that Lee's surrendering army "represented but a fraction of the Confederacy's men under arms, yet virtually everyone, North and South, interpreted Appomattox as the end of the war. [...] Wartime evidence points strongly to the conclusion that Lee was correct in believing he operated in the vital geographic area."
