In March 1864, Ulysses S. Grant was summoned from the Western Theater, promoted to lieutenant general, and given command of all Union armies. He left Maj. Gen. William Tecumseh Sherman in command of most of the western armies. Grant devised a coordinated strategy that would strike at the heart of Confederacy from multiple directions: Grant, George G. Meade, and Butler against Robert E. Lee near Richmond; Franz Sigel in the Shenandoah Valley; Sherman to invade Georgia, defeat Joseph E. Johnston, and capture Atlanta; George Crook and William W. Averell to operate against railroad supply lines in West Virginia; Nathaniel Banks to capture Mobile, Alabama. This was the first time the Union armies would have a coordinated offensive strategy across multiple theaters.

Grant and Meade attacked Lee's Army of Northern Virginia directly in the Overland Campaign. Butler's mission was to deploy his 33,000-man army via the James River to the Virginia Peninsula and strike northwest to Richmond. The objective was not to capture the Confederate capital directly, but to cut the Richmond-Petersburg Railroad—a critical Southern supply line—and force Lee to send reinforcements to that front, weakening him against Grant and Meade.

Butler was one of several political generals in the war—a man selected more for his support of Abraham Lincoln's upcoming re-election than his skill on the battlefield. His military career contained more controversies than victories. Grant hoped to compensate for Butler's weaknesses by assigning him two strong subordinate generals: Quincy A. Gillmore, commanding the X Corps, and William F. "Baldy" Smith, commanding the XVIII Corps. (Neither proved assertive enough to counteract Butler's inexperience.)

The campaign took its name from the fishing village of Bermuda Hundred on the peninsula at the confluence of the Appomattox and James rivers. The village is southeast of Richmond and northeast of Petersburg. It was downriver on the James from the practical limit of advance for Union warships, the fortifications at Drewry's Bluff.

Butler's Army of the James disembarked from navy transports at Bermuda Hundred on May 5, the same day Grant and Lee began fighting in the Battle of the Wilderness. He also dropped units at City Point, which could be used to threaten Petersburg. For a brief time, Butler attempted to move out smartly. Opposing him was a Confederate "army" (the Department of North Carolina and Southern Virginia) of 18,000 under Gen. P.G.T. Beauregard; some of these soldiers were pieced together from the ranks of teenagers and elderly men in the Richmond-Petersburg area, theoretically no match for Butler's soldiers. Beauregard's subordinate commanding troops around Petersburg was George Pickett of Pickett's Charge fame.

[edit] Battles

The battles fought during the Bermuda Hundred Campaign were:

Battle of Port Walthall Junction (May 6 – May 7, 1864)

On May 6, Brig. Gen. Johnson Hagood's brigade stopped initial Federal probes at Port Walthall Junction, a junction critical to controlling the railroad. On May 7, a Union division drove Hagood's and Bushrod Johnson's brigades from the depot and cut the railroad. Confederate defenders retired behind Swift Run Creek and awaited reinforcements.

Battle of Swift Creek (May 9)

Butler made a thrust toward Petersburg and was met by Johnson's division at Swift Creek. A premature Confederate attack at Arrowfield Church was driven back with heavy losses, but Union forces did not follow up. After skirmishing, Butler seemed content to tear up the railroad tracks and did not press the defenders. In conjunction with the advance to Swift Creek, five Union gunboats steamed up the Appomattox River to bombard Fort Clifton, while Brig. Gen. Edward W. Hincks's U.S. Colored Troops division struggled through marshy ground from the land side. The gunboats were quickly driven off, and the infantry attack was abandoned.

Battle of Chester Station (May 10)

Elements of Maj. Gen. Robert Ransom's division conducted a reconnaissance-in-force against a portion of Butler's army that was destroying the railroad at Chester Station. The Confederates attacked near the Winfree House, and the Federals retired to their Bermuda Hundred entrenchments.

Battle of Proctor's Creek (May 12 – May 16)

Butler moved north against the Confederate line at Drewry's Bluff but again adopted a defensive posture when his attack was not supported by gunboats. On May 13, a Union column struck the right flank of the Confederate line at the Wooldridge House, carrying a line of works. Butler remained cautious, however, giving Beauregard time to concentrate his forces. At dawn on May 16, Ransom's division opened an attack on Butler's right flank, routing many units. Subsequent attacks lost direction in the fog, but the Federals were disorganized and demoralized. After severe fighting, Butler extricated himself from battle, withdrawing again to his Bermuda Hundred line. Butler's offensive against Richmond was effectively ended.

Battle of Ware Bottom Church (May 20)

Confederate forces under Beauregard attacked Butler's line near Ware Bottom Church. About 10,000 troops were involved in this action. After driving back Butler's advanced pickets, the Confederates constructed the Howlett Line, effectively bottling up the Federals at Bermuda Hundred.
