Several of the Welsh internationals who had face the All Blacks, reneged on a promise to turn out for the Glamorgan team, so several positions needed to be hastily filled.
After competing in all 30 games of the 1904/05 season for Cardiff,[5] and facing the All Blacks for Glamorgan, Westacott was selected for his one and only international cap for the Wales team in the 1906 Home Nations Championship.
The Welsh selectors changed the team formation by dropping Billy Trew from centre and bringing in an extra forward.
Three new Welsh caps were brought into the pack, Westacott, Cardiff teammate Jack Powell and Llanelli's Tom Evans.
After taking the bunker positions around the farm, Westacott was killed in action the following day, and he is commemorated at Tyne Cot Memorial, Zonnebeke in Belgium.
