On 3 January 1916, Herring arrived in Alexandria with the 13th Battalion following the evacuation of Anzac. On 21 February 1916, the battalion was split, half going to form the new 45th Infantry Battalion. Herring took command of the new battalion, while Durrant resumed command of the old. Unfortunately, the new battalions soon had to absorb large numbers of men unwanted by the old battalions and left behind when they moved to France. On 12 March 1916, he became a temporary lieutenant colonel. He was promoted to the rank on 24 June 1916. The 45th Battalion departed Alexandria on 2 June 1916, arriving at Marseilles on 8 June. In August, the battalion was committed to the fighting at Pozières, losing 448 men on its first tour. For his leadership at Pozières, Herring was mentioned in dispatches and awarded the Distinguished Service Order (DSO).
