Custer then personally led an assault with his entire force but without a breakthrough. At about 9:00 p.m., under the light of a full moon, Custer's entire division again assaulted and finally broke the Confederate line. The Confederates began to withdraw, abandoning many of their active guns, caissons and baggage wagons which then were captured by Custer's men. The gradual dispersal of Walker's cannons and men and the withdrawal of Gary's and Talcott's men weakened Walker's remaining defense to the point of collapse upon Custer's final charge.
