"The Tree of Appomattox" concludes the series of connected romances dealing with the Civil War, begun in "The Guns of Bull Run," and continued successively through "The Guns of Shiloh," "The Scouts of Stonewall," "The Sword of Antietam," "The Star of Gettysburg," "The Rock of Chickamauga" and "The Shades of the Wilderness" to the present volume. It has been completed at the expense of vast labor, and the author has striven at all times to be correct, wherever facts are involved. So far, at least, no historic detail has been challenged by critic or reader. More than half a century has passed since the Civil War's close. Not many of the actors in it are left. It was one of the most tremendous upheavals in the life of any nation, and it was the greatest of all struggles, until the World War began, but scarcely any trace of partisan rancor or bitterness is left. So, it has become easier to write of it with a sense of fairness and detachment, and the lapse of time has made the perspective clear and sharp.
