He was mortally wounded on the night of 30 November 1864 along with his brother Lt. Joseph G.E. Williams.
Joseph had a arm shot off and Enoch was shot in the stomach.
It was a cold night and around daylight after the battle Enoch and Joseph were found wrapped in each others arms trying to stem the flow of blood from each others wounds before their deaths.
It is believed that both were buried together in the same grave on the battlefield.
Joseph's identify was not known at during the reburial of the soldiers into the cemetery, so he is probably buried there as an Unknown.
There are 565 Unknowns buried in the cemetery.
