In spite of the heavy fire he carried on with his well-organised arrangements. Later, whilst looking for a new dressing station, he was captured, but managed to make good his escape. Throughout the operations he displayed great energy, and his work was magnificent." and his 2nd Bar "For conspicuous gallantry and devotion to duty as liaison medical officer. He constantly kept tough with brigade and battalion headquarters, moving over roads and ground exposed to heavy shelling.
