The Battle of Chaffin’s Bluff

September 28, 1864 – Major General Benjamin F. Butler, commanding the Federal Army of the James, planned to send 20,000 men north to seize Confederate Forts Harrison and Gilmer, which made up a vital part of the Chaffin’s Bluff defenses southeast of the Confederate capital at Richmond, Virginia.

After Federal forces captured the Weldon Railroad south of Petersburg in August, both sides returned to their siege lines and regrouped for much of September. Most of the action in Virginia this month occurred in the Shenandoah Valley, with Major General Philip Sheridan’s Federals scoring major victories over the Confederate Army of the Valley under Lieutenant General Jubal Early.

President Abraham Lincoln worried that General Robert E. Lee, commanding the Confederate Army of Northern Virginia at Petersburg, would reinforce Early in the Valley. Lincoln wrote Lieutenant General Ulysses S. Grant, the overall Federal commander, “I hope it will lay no constraint on you, nor do harm anyway, for me to say I am a little afraid lest Lee sends re-enforcements to Early, and thus enables him to turn upon Sheridan.”

Grant replied, “I am taking steps to prevent Lee sending re-enforcements to Early by attacking him here.” This attack would consist of a two-pronged assault on Lee’s Confederates defending Richmond (i.e., their left flank) and those defending the South Side Railroad southwest of Petersburg (i.e., their right flank). Grant hoped to stretch the Confederate siege lines to their breaking point, thus leaving either Richmond, Petersburg, or both open to Federal capture.

Preparations for the attack on Richmond involved reuniting Butler’s army, which consisted of two infantry corps (X under Major General James B. Birney and XVIII under Major General E.O.C. Ord), and Brigadier General August V. Kautz’s cavalry. According to Butler’s plan:

  • Ord’s 8,000 troops would cross the James on a pontoon bridge and attack Forts Harrison and Gilmer at Richmond’s southern defenses near Chaffin’s Farm.
  • Birney’s 10,000 troops and Kautz’s horsemen would cross on Ord’s right, 18 miles downstream, and attack the Confederates’ easternmost defenses at New Market Heights.

Butler received intelligence (which proved correct) that the Confederate garrisons were lightly defended. Activity swirled around Butler’s headquarters the night before the attacks, as the commanders studied 16 pages of orders for this operation. A New York Times correspondent wrote, “Portents of a coming something were unmistakable. In all my experience, I never knew a plan to be kept so profoundly secret.”

Lee, whose army was spread dangerously thin already, began shifting troops from the Petersburg sector under Lieutenant General Richard H. Anderson to reinforce Lieutenant General Richard Ewell’s Confederate defenders outside Richmond. However, Butler’s secrecy ensured that the Confederates did not know where (or even if) an attack would take place.

On the night of the 28th, Ord’s Federals crossed the James at Aiken’s Landing and headed up the Varina Road, while Birney’s men crossed at Deep Bottom. Birney had orders to turn the enemy right at New Market Heights; this would push the Confederates away from Forts Harrison and Gilmer so Ord could capture them. Just 2,000 unsuspecting Confederates held New Market Heights against Birney’s entire corps.

Birney’s Federals advanced through the thick fog on the morning of the 29th. Brigadier General Charles J. Paine’s division led the assault, with a brigade of black troops in the frontline. The blacks charged unsupported, and many were either taken prisoner or killed after they surrendered. Birney regrouped and sent Paine’s troops forward again, this time supported by Brigadier General Alfred H. Terry’s division on their right. However, the Federals were stopped again by ferocious enemy fire.

As the Confederate fire slackened, the Federals launched a third charge that finally overran the works. But they soon learned that the Confederates had withdrawn because of the results of the fighting at Forts Harrison and Gilmer, not because of their charges. Paine’s division sustained 800 casualties, most of whom were black troops.

In Ord’s sector, the Federals had to charge over 1,400 yards of open ground, a desperate effort even with the benefit of fog. The Confederates were initially surprised by the enemy’s approach, but they quickly regrouped and poured heavy fire into the attackers. They killed hundreds of Federals in the first attack wave, including the wave commander, Brigadier General Hiram Burnham.

The subsequent attack waves were disorganized, but their sheer numbers overwhelmed the Confederates, and the Federals seized Fort Harrison by 7:30 a.m. The Federals then turned south to attack Fort Gilmer, the key to the Chaffin’s Farm defense line. The Confederate defenders at Gilmer had heard the firing at Harrison and were ready. They held firm with support from Confederate gunboats on the James, wounding Ord in the process. He was temporarily replaced as corps commander by Brigadier General Charles A. Heckman, with Major General Godfrey Weitzel replacing Heckman the next day.

Meanwhile, Kautz’s cavalry advanced down the Darbytown Road, but Confederate artillery drove them back. As the day ended, the Federals held Fort Harrison and New Market Heights, but the Confederates retained Fort Gilmer as they fell back to stronger, more compact defenses.

Ewell notified Lee that Fort Harrison had fallen. Fearing that this would open the road to Richmond, Lee hurried reinforcements to that sector and asked General Braxton Bragg, advisor to President Jefferson Davis, to call out all Richmond militia. Lee considered launching a night attack to retake Harrison but opted to wait until the next day. He reported that night, “The enemy still hold Battery Harrison on the exterior line. Our loss is very small.”

Both sides disengaged for the night, with the Confederates forming a new defense perimeter and the Federals fortifying against an expected attempt to retake Harrison the next day. Lee sent eight infantry brigades numbering 10,000 men north of the James for the impending assault.

On the 30th, the entrenched Federals easily repelled four desperate Confederate charges. Lee personally directed three of the assaults, fearful that losing Harrison might collapse his left flank. Brigadier General George J. Stannard led the strong Federal defense before being severely wounded in the final attack. Meanwhile, Federals made another effort to capture Fort Gilmer. Four companies of the 7th U.S. Colored Troops lost about half their men as they reached the fort’s ramparts, but the Confederates ultimately drove them off.

The Confederates who could not reclaim Harrison fell back to works between the fort and Richmond, beyond Federal gun range near Chaffin’s Bluff. This eventually became an even stronger line than the original one. Lee reported the loss of Harrison to the Confederate War Department that evening, as well as the loss of about 2,000 men in the two-day contest.

The Federals sustained 3,327 casualties (383 killed, 2,299 wounded, and 645 missing) out of about 20,000 engaged. Black troops comprised 1,773 of the total casualties, and of the 16 Congressional Medals of Honor earned by black soldiers in the war, 14 were awarded for this battle alone.

While the Confederates were now behind stronger defenses, Lee had no more men to reinforce either the troops stretching southwest of Petersburg or the Confederates in the Shenandoah Valley. Only a lack of effective Federal coordination prevented a major breakthrough that could have opened a path to Richmond.
