The Battle of Pickett's Mill (May 27, 1864) was fought in Paulding County, Georgia, between Union forces under Major General William Tecumseh Sherman and Confederate forces led by General Joseph E. Johnston during the Atlanta campaign in the American Civil War. Sherman sent Brigadier General Thomas J. Wood's division, supported by other formations, to turn Johnston's right flank, but the Federals were repulsed with heavy casualties when they ran into tenacious Confederate opposition. Author Ambrose Bierce, an eyewitness, later wrote an account of the battle titled The Crime at Pickett's Mill.
Earlier in May 1864, Sherman's army successfully compelled the Confederate Army of Tennessee to fall back to a strong defensive position at Allatoona Pass. Unwilling to attack Johnston's lines frontally, Sherman attempted a wide sweep around the Confederate western flank. Johnston quickly shifted his army southwest to block the move, and Sherman's first thrust at his opponent's defenses was defeated at New Hope Church. Both sides entrenched their positions. A day after Sherman's troops were beaten at Pickett's Mill, the Confederates launched an attack on the Union right flank which was repelled at Dallas. The two armies faced each other in the New Hope Church and Dallas lines until Sherman extended his left flank toward the railroad, compelling Johnston to retreat to a new position on June 4.
Background
Union Army
In the Atlanta campaign, William T. Sherman commanded a force made up of three armies drawn from the Military Division of the Mississippi. On April 30, 1864, the Army of the Cumberland led by Major General George H. Thomas included 73,000 troops and 130 guns, the Army of the Tennessee under Major General James B. McPherson numbered 24,500 soldiers and 96 guns, and the Army of the Ohio directed by Major General John Schofield reported 11,362 infantry, 2,197 cavalry, and 28 guns. Sherman's forces were supported by 25,000 non-combatants consisting of railroad employees and repair crews, teamsters, medical staff, and Black camp servants. Thomas' army was made up of Major General Oliver Otis Howard's IV Corps, Major General John M. Palmer's XIV Corps, Major General Joseph Hooker's XX Corps, and the 1st, 2nd, and 3rd Cavalry Divisions led by Brigadier Generals Edward M. McCook, Kenner Garrard, and Hugh Judson Kilpatrick, respectively. McPherson's army consisted of Major General John A. Logan's XV Corps and Brigadier General Grenville M. Dodge's Left Wing of the XVI Corps. Major General Francis Preston Blair Jr.'s XVII Corps joined McPherson's army on June 8. Schofield's small army included his own XXIII Corps and a cavalry division led by Major General George Stoneman. The IV and XX Corps each counted 20,000 soldiers, the XIV Corps had 22,000, the XV Corps numbered 11,500, and the XVI and XVII Corps each included about 10,000 men.
Confederate Army
Johnston's Army of Tennessee consisted of two infantry corps led by Lieutenant Generals William J. Hardee and John Bell Hood, and a cavalry corps under Major General Joseph Wheeler. Johnston's army was soon reinforced by the corps of Lieutenant General Leonidas Polk and the cavalry division of Brigadier General William Hicks Jackson from the Army of Mississippi. Hardee's corps included the divisions of Major Generals William B. Bate, Benjamin F. Cheatham, Patrick Cleburne, and William H. T. Walker. Hood's corps was made up of the divisions of Major Generals Thomas C. Hindman, Carter L. Stevenson, and Alexander P. Stewart. Polk's corps had the divisions of Major Generals Samuel Gibbs French and William Wing Loring, and Brigadier General James Cantey. On April 30, 1864, Johnston's Army of Tennessee reported 41,279 infantry, 8,436 cavalry, and 3,227 artillerymen serving 144 guns. Battles and Leaders calculated Johnston's reinforcements as follows: Brigadier General Hugh W. Mercer's brigade (2,800) on May 2, Cantey's division (5,300) on May 7, Loring's division (5,145) on May 10–12, French's detachment (550) on May 12, Jackson's cavalry (4,477) on May 17, French's division (4,174) on May 19, Brigadier General William Andrew Quarles' brigade (2,200) on May 26, and a 643-man detachment of Jackson's cavalry on June 10. Other reinforcements came from two Georgia state regiments (1,200), men returned from furlough, recruits, and returned deserters. There were about 8,000 non-combatants supporting Johnston's army, mostly men unfit for combat.
Operations
The Atlanta campaign began with the Battle of Rocky Face Ridge on May 5–9, 1864, when Sherman sent McPherson's two corps to turn Johnston's defenses from the west while Thomas and Schofield demonstrated frontally. Outflanked, Johnston retreated and fought the Battle of Resaca on 13–16 May, by which time Polk's corps began arriving. With his western flank menaced, Johnston withdrew again and Union troops captured Rome. At the Battle of Cassville on May 19, Johnston planned to counterattack part of Sherman's widely-spread army, but timing was ruined when McCook's cavalry appeared in an unexpected location. Johnston then took up a defensive position south of Cassville. Hood and Polk argued that the Cassville line was vulnerable to Union artillery fire, so Johnston retreated to Allatoona Pass on the night of May 19–20. Finding Johnston's position too strong to directly attack, Sherman decided to make another maneuver around Johnston's western flank. After pausing operations for three days, Sherman sent McPherson's right wing south to Van Wert and then east toward Dallas. Thomas's army formed Sherman's center and Schofield's corps his left.
At the start of the latest Union maneuver, Sherman ordered 20 days rations be carried in his wagons because they were leaving the proximity of the railroad. Thomas' army crossed the Etowah River and marched through Euharlee and Stilesboro, while Brigadier General Jefferson C. Davis' 2nd Division, XIV Corps, which was detached at Rome, joined the movement of McPherson's wing. Blair's XVII Corps was approaching from the north, but had not yet joined Sherman. Garrard's cavalry preceded McPherson's columns, McCook's cavalry covered Thomas' front, Stoneman's cavalry headed Schofield's columns, and Kilpatrick's cavalry watched the railroad north of the Etowah. Johnston received news of Sherman's move from Jackson's cavalry, and on the afternoon of May 23, he ordered Hardee's corps to march to Dallas and Polk's corps to follow. On May 24, Johnston ordered Hood's corps to join the others. By May 25, Johnston's army was positioned so that Hardee's corps was on the left near Dallas and Hood's corps was on the right at New Hope Church. Polk's corps was posted to the left of Hood, with a lightly defended gap between Polk and Hardee.
Hooker's XX Corps led the advance of Thomas' Army of the Cumberland. When it reached Pumpkinvine Creek at Owen's Mill, the Federals drove off some Confederates who were trying to burn the bridge. Strongly resisted by three Confederate regiments, Brigadier General John W. Geary's 2nd Division pressed forward until it came into contact with Hood's corps at New Hope Church. It was 5 pm before Hooker was able to reinforce Geary with the divisions of Brigadier General Alpheus S. Williams (1st) and Major General Daniel Butterfield (3rd). Each of the three divisions were formed into brigade columns, that is, with the leading brigade deployed and the two other brigades of the division directly behind it. In the Battle of New Hope Church on May 25, Hooker's divisions repeatedly assaulted the ridge that Hood's troops defended, but without success. The battle lasted three hours, and during its last hour a thunderstorm rumbled overhead. Hooker admitted sustaining losses of 1,665 killed and wounded in a place the Union troops began calling the "Hell Hole". Stewart's division, which was the main defending force, reported losing 300–400 casualties.
The leading unit of Howard's IV Corps, which was Brigadier General John Newton's 2nd Division, arrived in the area of New Hope Church at 6 pm and was placed in line on the left of Hooker's corps. By the morning of May 26, Howard's entire corps was fully deployed. Regarding Palmer's XIV Corps, Brigadier General Absalom Baird's 3rd Division was assigned to guard Thomas' wagon train at Burnt Hickory and Brigadier General Richard W. Johnson's 1st Division was placed in reserve behind Hooker. On the morning of May 26, McPherson's two corps occupied Dallas and confronted Hardee's corps about 2 mi (3.2 km) farther east. McPherson deployed Logan's XV Corps on the right, Dodge's XVI Corps in the center, and Davis' XIV Corps division on the left. Between Davis and Hooker, there was a lightly defended area. Schofield's XXIII Corps left Brigadier General Alvin Peterson Hovey's division to watch the wagon train and proceeded with the divisions of Brigadier Generals Jacob Dolson Cox and Milo S. Hascall. Schofield's corps reached the battlefield after an all night march in the rain. During the night, Schofield was injured when his horse fell into a ravine, so Cox temporarily assumed command of the corps. In the morning, Sherman directed the corps to the left of Howard's corps and, after marching by compass through thick woods, it came into line near Brown's saw-mill. At this point, the XXIII Corps and the left of the IV Corps made a right wheel to face toward the Confederate defensive positions. On May 26, both sides entrenched and the day was notable for the continuous skirmishing that took place between the two sides.
Battle
The maneuver
Sherman decided to turn Johnston's right flank. Aware of his numerical superiority, and with both armies entrenched, Sherman decided that he could assemble some of his troops and use them to outflank the Confederate defenses. In addition, by extending his left flank northward, Sherman was able to get closer to the railroad line. Also on May 26, McCook's cavalry bested Wheeler's horsemen in a skirmish, capturing 50 Confederates. This clash seemed to indicate that Johnston's right flank was only defended by cavalry.
On May 27, the artillery of Schofield, Howard, and Hooker bombarded the Confederate defenses starting at dawn, and the opposing batteries replied. Sherman wanted Howard, supported by Schofield's divisions, to thrust at what he believed to be Johnston's right flank while McPherson pressed back the Confederate left flank. At dawn, Howard withdrew Thomas J. Wood's division (IV Corps) from its newly dug trenches and replaced it with David S. Stanley's division. As Wood's division marched north, Thomas and Howard conducted a reconnaissance of the location where Sherman wanted to attack. Finding that the assault would have to cross an open field subject to Confederate cross fire, Thomas instructed Howard to shift the assault location farther north, to the left of Schofield's lines. Thomas also detached Johnson's 1st Division from XIV Corps so that it could support Wood's attack. Furious that first Davis' and now Johnson's divisions were taken away from him, Palmer threatened to resign command of XIV Corps, and Thomas had to talk him out of it.
At 11 am, Wood's division was formed into a column of brigades with each brigade formed into two lines, so that the division was deployed into six lines, one behind the other. Johnson's division was formed into a similar column. The Union divisions marched through forests so dense that Wood gave the colonel of his leading regiment a compass to guide the movement. After marching 1.5 mi (2.4 km), Howard ordered Wood's and Johnson's columns to turn to the right and prepare to attack. Wood's skirmishers went forward and discovered entrenched Confederates in front, so Howard decided to attack farther north. Howard ordered Brigadier General Nathaniel McLean's brigade to support Wood's right flank; McLean's command was the 3rd Brigade, 3rd Division, XXIII Corps. The crucial defense of McLean's brigade at the Second Battle of Bull Run may have prevented a Union catastrophe, but bad blood existed between McLean and Howard. Historian Albert Castel asserted, "Of all the brigade commanders in Sherman's army, a worse one to assist in Howard's attack could not have been found." Howard blamed McLean among others for the disaster to XI Corps at the Battle of Chancellorsville and McLean detested Howard for it.
