On the same day (31st of March), Warren advanced his corps from the neighborhood of Armstrong's Mill towards Five Forks; so that when the engagement between Sheridan and Fitz Lee closed for the night, Warren's, corps was on Fitz Lee's flank, and almost in his rear. Pickett and Fitz Lee, perceiving the conditions, fell back at light the next morning (April 1st), and arranged their commands in line of battle at Five Forks, with Pickett's division in line, Munford covering its left flank, W.

He then quickly moved upon it, doubled it up, and drove it from the field in the utmost confusion towards the west, and captured the greater part of the artillery and many prisoners.

Anderson, who was at Burgess' Mill with Johnson's division, that the Fifth Corps was with Sheridan, and that Sheridan, now with overwhelming force, was pressing upon him. Anderson, in person, with Wise's and Gracie's brigades, moved to his relief, but as Warren had
