on his map of every unit engaged in the battle. That fall he published a panoramic view of Gettysburg. During visits to the Army's winter quarters, he claims to have interviewed the commanders of every regiment and battery in the Army of the Potomac. He later organized reunions on the field and accompanied veterans over the terrain and placed wooden stakes into the ground to identify important points of the battle. In 1870, noted artist James Walker was commissioned by Bachelder to paint an account of Pickett's Charge, entitled "The Repulse of Longstreet's Assault at the Battle of Gettysburg," a massive work that measured 7.5 by 20 feet. Bachelder wrote an accompanying guidebook and toured widely with the canvas, lecturing across the United States. In 1873, he published a guidebook to the battle, which was well received by the public. Bachelder's contribution to Gettysburg was more than artistic. From 1883 to 1887, he served in the position as Superintendent of Tablets and Legends for the Gettysburg Battlefield Memorial Association, and is probably responsible more than any man for the placement of monuments and battlefield markers, both Union and Confederate. He coined the phrase "Copse of Trees" and invented the concept of a "High Water Mark of the Confederacy" at which the famous Pickett's Charge peaked. All but a few monuments on the battlefield bear some of his influence. In 1880, President Rutherford B. Hayes signed into law a bill that provided $50,000 to Bachelder to write a detailed history of the battle of Gettysburg. Bachelder based his manuscript on the Official Records and the interviews he had done, but he has been criticized by some historians because his personal interviews, which would be considered more accurate than reports compiled years after the event, affected only about 10% of the 2,550 pages that he sent to Washington in October 1886. Southern historians also complained that he chose to interview very few Confederate officers. Bachelder's activities at Gettysburg were described in detail by Senator Wade Hampton of South Carolina on March 17, 1880, in a report to the Senate from its Military Affairs Committee: Death Bachelder died of pneumonia in Hyde Park, Massachusetts, in 1894. His body was then transported the 79 miles to be buried alongside his only child, Charlotte who had died at age 13. Their graves are located in a small family cemetery on Stevens Hill Road in Nottingham,
