In October 1914 French and British artillery commanders met to discuss means for supporting infantry attacks, the British practice having been to keep the artillery silent until targets were identified, the French artillery fired a burst of fire (), which ceased as the infantry began the assault. A moving barrage of fire was proposed as a combination of both methods and became a standard practice once when guns and ammunition were accumulated in sufficient quantity. Falkenhayn issued memoranda on 7 and 25 January 1915, defining a model of defensive warfare to be used on the Western Front, to enable ground to be held with the fewest possible troops. By reducing demand for manpower in the west, a larger number of divisions could be sent to the Eastern Front.
