Grant abandoned the stalemate following the Battle of North Anna (May 23–26) by once again swinging widely around Lee's right flank, using the Pamunkey River to screen his movements to the southwest.
But Hampton had held up the Union cavalry for seven hours, prevented it from achieving its reconnaissance objectives, and had provided valuable intelligence to General Lee about disposition of Grant's army.
Gen. James H. Wilson to Little River, probing the western end of the Confederate line, while at the same time men from the cavalry divisions of Brig.
Gregg were sent to the Little Page Bridge and Taylor's Ford on the Pamunkey, 10 miles upriver from Grant's intended crossing points.
Lee, who was still in his tent suffering from the diarrhea that had incapacitated him during the North Anna battle, was fooled by Grant's actions and assumed that the Union general would be moving west for the first time in the campaign.
He also sent a small brigade of North Carolina and Virginia cavalry down the southern bank of the Pamunkey to scout and harass the Union advance wherever possible.
Ewell was also laid up with a similar illness and rode in an ambulance; his condition was serious enough that he was temporarily replaced in command by Maj. Gen. Jubal Early.
Gen. George A. Custer's Michigan cavalry brigade scattered the mounted Confederate pickets guarding the ford and an engineer regiment constructed a pontoon bridge.
Gen. Matthew C. Butler (the newly formed and inexperienced 4th and 5th South Carolina cavalry regiments, commanded temporarily by Col. B. Huger Rutledge, and the 20th Georgia Battalion under Lt. Col. John M. Millen), and several sections of horse artillery.
Three miles west of Hanovertown, and a mile beyond a large blacksmith shop called Haw's Shop, Gregg's troopers ran into Hampton at Enon Church, finding the Confederate cavalrymen dismounted in a wooded area, hurriedly erecting breastworks made of logs and rails, and well covered by artillery.
As Davies rode into the fighting, his saber was cut in half by a Minié ball and his horse's tail was shot off.
Gen. Wesley Merritt extended Gregg's line to the right, thwarting a flanking maneuver attempted by Hampton with Chambliss's newly arrived brigade.
[15] There was plenty of infantry nearby that could have been called for reinforcements, with Maj. Gen. Winfield S. Hancock's II Corps dug in about one mile to the north.
However, Custer inspired his men by staying mounted as he led them forward, waving his hat in full view of the enemy, while his brigade band played Yankee Doodle.
Receiving heavy rifle and artillery fire, 41 of the Union cavalrymen fell in the attack, as did Custer's horse—the seventh time the flamboyant general lost a horse during the war.
Meanwhile, on the northern end of the battle, a Confederate mistakenly identified some dismounted Union cavalrymen as infantry and reported this to Hampton.
Concerned that his cavalry command would be isolated and overwhelmed by an infantry attack, Hampton gave the order to begin withdrawing.
(Hampton had also just received intelligence from prisoners on the location of two Union corps that had crossed the Pamunkey, which meant that his reconnaissance mission had been successfully completed.
Custer took advantage of the situation by charging forward, overrunning the Georgians, killing their commander, Lt. Col. John M. Millen, and capturing many of his men.
Davies's brigade joined the attack and the remaining Confederate line fell apart into a rout, but by nightfall Hampton's cavalry was safely west of Totopotomoy Creek.
[19] Union casualties were 256 men in Gregg's division and another 41 from Custer's brigade, including Private John Huff, the cavalryman from the 5th Michigan who had fatally shot Maj. Gen. J.E.B.
Confederate losses were never tabulated officially, but Union reports claimed they buried 187 enemy bodies after the battle, recovered 40 to 50 wounded men, and captured 80 South Carolinians.
He has been criticized by historians such as Gordon Rhea for missing an opportunity to destroy Hampton's command while it was isolated and vulnerable in front of the Totopotomoy, something that could have been accomplished if Sheridan had devoted his entire Cavalry Corps to the task.
And rather than attempting to maneuver on several of the roads that led to Hampton's rear, Sheridan's command expended their efforts on costly frontal assaults.
