Roedd Brwydr Coedwig Mametz yn ffyrnig a bu llawer iawn o anafiadau. Gyda'r ardal wedi'i dinistrio gan ffrwydron trwm a pharhaus, ac er gwaethaf y coed a'r isdyfiant trwchus, cyflawnodd y 38ain Adran (Gymreig) ei hamcan i gipio’r goedwig erbyn y pumed diwrnod.
The Battle of Mametz Wood was fierce and there were heavy casualties. With the area obliterated by heavy and continuous artillery shells, and despite thick trees and dense undergrowth, the Welsh Division fulfilled its objective to capture the wood by the fifth day.
