At the outset of 1918 Germany faced certain defeat as a result of Allied technical innovation in tanks and aircraft, and the American entry into the war. Victory could only be gained by the immediate application of overwhelming force in new tactical form; the 'fire-waltz' artillery barrage and the storm-trooper infantry attack. 1918 examines both the Germans' tactics and the Allies' preferred solution to fighting this war, the combination of artillery, tanks, infantry and aircraft, and argues that this reached a level of sophistication in command and control never before achieved. The war of attrition was far from over, but as more Americans arrived in France the ghastly cost became affordable. For the Germans, it became a question of whether they could negotiate an armistice before their armies were utterly destroyed.
