Confederates hovering near his flank, at about 3 p.m. Sheridan sent Torbert's three brigades, supported by Davies's brigade of Gregg's division, on a reconnaissance west on the Gordonsville and Charlottesville roads. They found Hampton's entire force in an L-shaped line behind some log breastworks at the Ogg and Gentry farms, two miles northwest of Trevilian. Torbert launched seven assaults against the apex and shorter leg of the "L", but his brigades were repulsed with heavy losses. Fitzhugh Lee detached his division from the line and his brigades under Wickham and Lomax swung around to hit the Union right flank with a strong counterattack. The battle ended about 10 p.m., with both sides remaining in place. Late in the night, however, Torbert withdrew. Sheridan, burdened with many wounded men, disproportionately from Custer's brigade, about 500 prisoners, and a shortage of ammunition, decided to withdraw. He planned a leisurely march back to Cold Harbor, knowing that Hampton would be obliged to follow and would be kept occupied for days, unavailable in that time to Robert E. Lee. Aftermath The results of the Battle of Trevilian Station were mixed. Union casualties were 1,007 (102 killed, 470 wounded, and 435 missing or captured). Confederate losses were reported as 612, but this includes the losses from only Hampton's Division and 831 is a better total estimate. It was the bloodiest and largest all-cavalry engagement during the war. Sheridan maintained that the battle was a Union victory. In 1866, he wrote, "The result was constant success and the almost total annihilation of the rebel cavalry. We marched when and where we pleased; were always the attacking party, and always successful." Ulysses S. Grant's personal memoirs agreed with the sentiment and many of Sheridan's biographers accept his claim. As a diversion, it can be considered a partial success for the Union; it was not until Grant began attacking the weak forces at Petersburg that General Lee finally understood that the Union Army had maneuvered away from him and crossed the James River. However, Sheridan failed in two important objectives. He was unable to permanently disrupt the Virginia Central Railroad because within two weeks the track was repaired and supplies continued to flow to General Lee's army. The planned rendezvous between Sheridan and Hunter failed completely. Hunter was subsequently defeated at the Battle of Lynchburg (June 17–18) by Lt. Gen. Jubal Early in the Valley and was soon
