John Bankhead Magruder was an American and Confederate military officer. A graduate of West Point, Magruder served with distinction during the Mexican–American War (1846–1848) and was a prominent Confederate Army general during the American Civil War (1861–1865). As a major general, he received recognition for delaying the advance of Maj. Gen. George B. McClellan's large force, the Army of the Potomac, during the 1862 Peninsula Campaign, as well as recapturing Galveston, Texas the following year.

The Battle of Malvern Hill, also known as the Battle of Poindexter's Farm, was fought on July 1, 1862, between the Confederate Army of Northern Virginia, led by Gen. Robert E. Lee, and the Union Army of the Potomac under Maj. Gen. George B. McClellan. It was the final battle of the Seven Days Battles during the American Civil War, taking place on a 130-foot (40 m) elevation of land known as Malvern Hill, near the Confederate capital of Richmond, Virginia and just one mile (1.6 km) from the James River. Including inactive reserves, more than fifty thousand soldiers from each side took part, using more than two hundred pieces of artillery and three warships.
