On 23/24 March 1918 at Montagne Bridge, France, the enemy had gained a position on the south bank of the canal and Second Lieutenant Herring's post was surrounded, but he immediately counter-attacked and recaptured the position, together with 20 prisoners and six machine-guns. During the night the post was continually attacked, but all attacks were beaten off, largely because Lieutenant Herring was frequently visiting his men and cheering them up. It was owing to his bravery and magnificent handling of his troops that the enemy advance was held up for 11 hours at a very critical period.
