Boonsboro, or Turner's Gap, the Fox's Gap, and the Crampton's Gap to give him time to bring back the Second corps and pull together the Army of Northern Virginia at Sharpsburg. On September 14, 1862, Union troops from the Army of the Potomac moved to seize the passes and advance toward Boonsboro where the wagon trains and parks of artillery of the Army of Northern Virginia were kept. McClellan expected to meet with strong opposition at the South Mountain, but in reality the Confederates there were greatly outnumbered by the Federals. The main points of contention were two South Mountain passes, the Turner's Gap and the nearby Fox's Gap, as they provided the shortest access to Boonsboro. Hill wrote in his memoir, The Battle of South Mountain, or Boonsboro: Fighting For Time at Turner's and Fox's Gaps, that after the Federal artillery started firing at 9 a. m. he instructed Garland to defend the National Pike, which was leading through the Turner's Gap towards Boonsboro, at all costs: About 3,000 Federals belonging to General Jacob D. Cox's division from Gen. Jesse L. Reno corps, including Lieutenant-Colonel Rutherford B. Hayes of the 23d Ohio regiment, attacked Garland's men whose number was at "scarce a thousand." The Federals pressed north toward Fox's and Turner's Gaps. During the spirited mid-morning engagement at Fox's Gap, Garland was mortally wounded while commanding his men who were defending a stone wall bordering farmer Daniel Wise's field along Old Sharpsburg Road. He died within minutes. Colonel Duncan K. McRae, of the 5th North Carolina Regiment, assumed command after Garland's death. Garland's body was retrieved by Confederate troops and sent down the mountainside. On September 19, 1862, Garland was buried in the Presbyterian Cemetery in his hometown of Lynchburg next to his wife and son. Family Garland's maternal grandmother was Lucinda Rose Garland, a daughter of Dr. R.H. Rose and Frances Madison, who was a sister of President James Madison. His uncle, John Garland, was a U.S. Army general and fought in many different wars including, the War of 1812, Seminole Wars, Mexican–American War, Utah War and very briefly in the American Civil War on the side of the Union. Remembrance In his official report after the Battle of South Mountain, Garland's commanding officer, Maj. Gen. D.H. Hill memorialized him by writing, "This brilliant service, however, cost us the life of that pure, gallant, and accomplished Christian soldier,
