Historian A. Wilson Greene has written that the best estimate of Confederate casualties is 360 cavalry, 400 infantry, 760 total. Statements show that some Confederates also were taken prisoner. Sheridan suffered 40 killed, 254 wounded, 60 missing, total 354. Pickett lost General Terry to a disabling injury. He was replaced as brigade commander by Colonel Robert M. Mayo. Sheridan's messages to Grant Late in the afternoon Grant sent his aide-de-camp Lieutenant Colonel Horace Porter to report on Sheridan's situation. He arrived as Gregg's and Gibb's brigades were falling back from the junction of Adams and Brooks roads. Porter met Sheridan just before reaching Dinwiddie Court House. Sheridan told Porter he had had one of the liveliest days in his experience, fighting infantry and cavalry with only cavalry. Since his men were concentrating on high ground just north of Dinwiddie Court House, he would hold his position at all hazards. Sheridan reiterated that with a corps of infantry, he could cut off the whole force that Lee had detached and sent against him. Sheridan said that Pickett was in more danger than he was. Historian A. Wilson Greene has stated that the significance of the battle transcended the modest number of casualties. As Sheridan told Colonel Porter: "This force is in more danger than I am - if I am cut off from the Army of the Potomac, it is cut off from Lee's army, and not a man in it should ever be allowed to get back to Lee. We at last have drawn the enemy's infantry out of its fortifications, and this is our chance to attack it." Sheridan asked Porter to hasten back to Grant and to ask Grant to send him the VI Corps but Porter repeated Grant's earlier statement to Sheridan that Wright was on the right of the Union line and the only infantry corps that could promptly join Sheridan was Warren's V Corps. Sheridan appears not to have been as confident as he led Porter to believe because in a letter to Grant sent with a later dispatch via an aide, Colonel John Kellogg, he wrote that "This force (Pickett's) is too strong for us. I will hold on to Dinwiddie Court-House until I am compelled to leave." Porter made his report to Grant at Dabney's Mill at 7:00 p.m. The later reports carried to both Meade and Grant via Sheridan's brother Michael, one
