Warren was. Chamberlain replied that he thought he was at the rear of the column. Sheridan exclaimed: "That's just where I should expect him to be." Warren's men knew this was an unfair comment because Warren had never shown a lack of personal bravery. Sheridan instructed Griffin to place his men south of J. Boisseau's farm, while Ayres's remained south of Griffin. Warren and Crawford's division arrived soon thereafter. At 6:00 a.m., Meade's Chief of Staff, Brigadier General Alexander S. Webb, had sent an order to Warren to report to Sheridan for further orders. Two of Warren's divisions had done so within an hour of that message. A staff officer rode up to Warren at about 9:30 a.m. and handed him Webb's message. At the same time that Webb sent this message to Warren, 6:00 a.m., Meade sent a telegram to Grant stating that Warren would be at Dinwiddie soon with his whole corps and would require further orders.

Breaking camp at 3:30 a.m., Mackenzie's troopers rode toward Dinwiddie Court House over the Monk's Neck and Vaughan Roads. Pickett withdraws to Five Forks Pickett realized his position was untenable after he learned between 9:00 p.m. and 10:00 p.m. that Bartlett's brigade was on its way to reinforce Sheridan, exposing his force to flanking Union infantry attack. So Pickett withdrew to Five Forks by 5:00 a.m., giving up any advantage his attack on Sheridan might have gained. Bartlett's brigade was only the lead unit for all of Griffin's and Crawford's divisions which were put on the march later that night and would have trapped Pickett's force between them and Sheridan's troops. This would have given the Confederate force no apparent alternatives other than surrender or flight to the west. Pickett's retreat gave him an opportunity to defend Five Forks and the South Side Railroad. When Sheridan discovered the Confederates were pulling
