After training in Ireland and Aldershot, he went to the front with the Jersey Company in December 1915. He appears to have remained with them through 1916 and into 1917 until seriously wounded while on patrol near Cambrai in December. It was his brother Robert who found and carried him to a Casualty Clearing Station where he subsequently died. In a letter to his parents explaining the death, CQMS Mallet wrote that Archibald was 'an exceedingly smart NCO … and was held in high esteem'.
Originally a bugler, while in Ireland he became 'Company Piper'.
Commemorated on Old Boys of St James' Company Boys Brigade Memorial
