Dan Sickles at Gettysburg

I have been reading a book on northern generals by Wilmer Jones ("Generals in Blue and Gray: Lincoln's Generals," Vol. I, Stackpole Books, 2004). In the chapter on Dan Sickles, Jones talks about two things I found particularly interesting. First, after the war, Sickles was instrumental in the creation of the Gettysburg National Park. One observer noted that there were no monuments for Sickles in the Park, and Sickles replied, "Hell, the whole damn battlefield is my monument." Second, Jones notes that Sickles always believed his actions at the Peach Orchard, etc., saved the Union from defeat by blunting Longstreet's attack on the second day. Moreover, after the war, Longstreet sent Sickles a letter, published in several newspapers, crediting Sickles with slowing his attack on July 2, 1863, allowing Northern troops time to occupy Little Round Top.
