His MID and likely the cause of the DCM: "22123 Troop-Quarter-Master-Sergeant J. Newnham, 22864 Sergeant S. Grist, and 22442 Corporal J. Wilson, “A” Pontoon Troop. – Conspicuous bravery and coolness when laying and working at pontoon bridge under fire on several occasions, specially at Munger’s Drift on 5th February (1900)”.
Munger’s Drift was the pontoon crossing of the Tugela River opposite the Doorn Kloof Ridge and the Boer artillery emplacements at Vaal Krantz. After an initial period of quiet the Boers began to pour a “hot and terrible fire from their rifles and a machine gun” onto the British troops. The Royal Engineers, from the very nature of their work, could take no cover.
