The relief maps of the Gettysburg National Military Park, on exhibition at the office in the Federal Building, in Gettysburg, were designed by the Engineer of the Commission, Colonel E. B. Cope, and built under his supervision. The largest reproduces 24 square miles and correctly delineates all the topographical features of the Park. Many of the monuments and markers erected by the Commission were also designed by Colonel Cope. The imposing stone gateway at the entrance to Hancock Avenue was proposed by the Chairman, Colonel Nicholson, and designed by the Engineer. This gateway is built of native granite taken from the battlefield. Celebrations, reunions, dedications, and campfires almost without number have been held at Gettysburg, bringing to the field those who participated in the battle, their families and friends, and many other visitors. For many years, until a permanent camp was established at Mt. Gretna, the National Guard of Pennsylvania encamped on the field. The two greatest occasions were the Twenty-fifth Anniversary in 1888, and the Fiftieth Anniversary in 1913. The latter was attended by almost 55,000 survivors of the two armies. Ample accommodations were provided for their comfort and enjoyment. The time extended over a period of eight days, June 29th to July 6th, and every State in the Union was represented. The men who had met as mortal enemies fifty years before now met as brothers. The American soldier is not only a good fighter but also a good friend. Many donned their uniforms of ’63, some of Blue and some of Gray, but in the wearers great changes had been wrought. The sturdy veterans who in the vigor of their youth met fifty years before in battle, returned grizzled with age and the ravages of war, many bearing scars. With keen interest, in pairs and groups, they moved from place to place relating to each other their experiences. In startling contrast to the 45,000 casualties of ’63 there were only seven deaths, and these from the infirmities of age and natural causes. The President of the United States and many able speakers from all sections of the country made addresses to large audiences. It was an event never to be forgotten and did much finally to heal the animosities engendered by the war. On July 3, 1922, Marines from Quantico, Va., under the command of Brigadier-General Smedley D. Butler, repeated Pickett’s Charge as it was made in 1863, and on July 4th conducted it as such a charge would be made under present warfare conditions with modern equipment and maneuvers. President Harding, General Pershing, and many others prominent in the State and Nation enjoyed the display.
