Union Colonel Peter Stagg's brigade of Brigadier General Thomas Devin's cavalry division joined with Major General Horatio Wright's VI Corps in an attack on Ewell's stalled division. The Union forces caught up to Anderson's and Ewell's corps, who were without artillery, as the Confederates were positioned almost back-to-back near Sailor's Creek. Ewell's corps was almost surrounded and all but about 250 of his men from a reported 3,400 men then in the corps were casualties, mostly captured. Anderson lost about 2,600 men out of 6,300. Eight generals were captured including Ewell and Lee's son, Major General George Washington Custis Lee.
