'For conspicuous gallantry and constant devotion to duty during operations around Bapaume and near Gouzeaucourt from August 25th to September 13th, 1918. This man was in charge of the Battalion Stretcher bearers and his work, while of a most trying and exhausting nature has been splendidly carried out. Under very heavy artillery and strong machine gun fire Allason repeatedly led forward his parties collecting the wounded. On 12th September when several of his bearers were wounded he organised new parties and was largely instrumental in clearing the battle field so quickly. This man has always shown a wonderful contempt for danger and has constantly run great risks for the sake of the wounded.'
