Georgia: The Armies Gather at Resaca

May 13, 1864 – Major General William T. Sherman shifted his Federals southeast to try moving around General Joseph E. Johnston’s flank, but Johnston shifted to block them.

Sherman had assigned Major General James B. McPherson to lead his Army of the Tennessee around the Confederate left and capture Resaca. However, McPherson had failed to use his 23,000 troops to knock the 4,000 Confederates out of town before they were reinforced. This meant that Johnston’s communication and supply lines (and perhaps most importantly, his line of retreat) remained intact.

Although frustrated, Sherman acknowledged that McPherson had used sound judgment. He wrote McPherson, “I regret beyond measure that you did not break the railroad, however little, but I suppose it was impossible. Should he attack you, fight him to the last and I will get to you.” Sherman later told him, “Well, Mac, you missed the opportunity of your life.”

Sherman opted to go with the plan originally conceived by Major General George H. Thomas, commander of the Federal Army of the Cumberland, which entailed a much larger Federal movement around Johnston’s left flank. Sherman informed his superiors at Washington that he intended to move “between Johnston and Resaca, when we will have to fight it out.”

The Federals spent the 10th probing the Confederate defenses at Rocky Face Ridge, Buzzard’s Roost Gap, and points farther south. Unable to dislodge Johnston from such strong positions, Sherman hoped to send his entire force around the Confederate left, through Snake Creek Gap, and attack Resaca with overwhelming force. This would isolate Johnston north of the Oostanaula River.

Meanwhile, Johnston dispatched three divisions from Lieutenant General John Bell Hood’s corps to hold Resaca. They reported that McPherson had fallen back, leaving Johnston confused as to Sherman’s real intent. Johnston therefore opted to defend Dalton, Resaca, and all points in between. The Confederates had the advantage of holding the interior line, which ran 18 miles from Dalton to Resaca via the Western & Atlantic Railroad.

That night, Lieutenant General Leonidas Polk’s Confederate Army of Mississippi began arriving in bulk and taking up positions at Resaca. Polk himself arrived to take command in the area the next day. Polk’s army thereafter became known as “Polk’s Corps” of Johnston’s Army of Tennessee.

Sherman issued marching orders on the 11th. McPherson would stay put while the armies of Thomas and Major General John Schofield would swing southeast along Taylor Ridge to join McPherson’s army at Snake Creek Gap. A small Federal force would remain at Rocky Face Ridge as a diversion, consisting of IV Corps and two mounted divisions. Major General Oliver O. Howard, commanding IV Corps, was “terrified” by the idea of facing the Confederates at Rocky Face alone. However, Johnston remained purely on the defensive and did not threaten his small force.

The Federal advance was extremely slow because the troops, guns, and wagons all used just one road. This gave Johnston’s scouts time to confirm that the main Federal movement was taking place to the west, around the Confederate left. The next day, Major General Joseph Wheeler’s cavalry scouts reported that just a skeleton force remained at Rocky Face Ridge, thus proving that Sherman’s intent was to slide around the left.

Johnston ordered Lieutenant General William Hardee’s corps and the rest of Hood’s corps to fall back and join Polk at Resaca. The Confederates began evacuating Dalton on the night of the 12th. Meanwhile, Sherman’s Federals still had not fully arrived at Snake Creek Gap due to the delays that came with marching along a single road.

On the morning of the 13th, the withdrawing Confederates began arriving at Resaca, a town within a peninsula formed by the Oostanaula and Conasauga rivers. The Federals began probing through Snake Creek Gap but were stopped by Polk’s Confederates. This gave the rest of Johnston’s men time to take positions on the high ground west of town.

Johnston hoped to stay on the defensive and stretch the Federal supply lines to the point where Sherman would have to either engage in an open fight or fall back for sustenance. Sherman hoped to cut Johnston off from the Oostanaula, but by the time he was ready to advance in force, the Confederate wagon train was already crossing that river.

The Federals finally began advancing through Snake Creek Gap in force. McPherson’s army was on the right (south), with its right flank anchored on the Oostanaula, and Thomas’s army was on the left. Schofield’s army was held in reserve, east of the gap. The opposing line consisted of Polk on the left (south), Hardee in the center, and Hood on the right.

Sherman did not expect Johnston to put up a fight; he believed that Johnston just wanted to stall until his wagons got over the river. He therefore directed McPherson and Thomas to demonstrate in the Confederate front while Schofield’s Federals built bridges over the Oostanaula and crossed over to cut off the Confederate line of retreat. The action would begin the next morning.
