Returning to the front lines in November, he fought in Artois, participating in the battle for the town of Neuville-Saint-Vaast. After two months out of action with a throat infection, Hess served in the Battle of Verdun in May, and was hit by shrapnel in the left hand and arm on 12 June 1916 in fighting near the village of Thiaumont. After a month off to recover, he was sent back to the Verdun area, where he remained until December.[5][6]
