Plan 1919 was a military strategy drawn up by J.F.C. Fuller in 1918 during World War I. His plan criticised the practice of physically destroying the enemy, and instead called for tanks to rapidly advance into the enemy's rear area to destroy supply bases and lines of communication, which would also be bombed. He suggested a lightning thrust toward the command center of the German Army:
"... every available bombing machine should concentrate on the various supply and road centres. The signal communication should not be destroyed, for it is important that the confusion resulting from the dual attack carried out by the Medium D tanks and aeroplanes should be circulated by the enemy. Bad news confuses, confusion stimulates panic … (then) a carefully mounted artillery, tank and infantry attack should be launched, the objective of which is the zone of the enemy's guns: namely the secondary tactical zone some 10,000 yards deep."
"so does an army depend for its power on the will of its Commander and his Staff: cut that will off and the army will be paralyzed." He proposed using Medium D tanks "to disorganise the enemy’s Command in rear of the entrenched zone."
The Allied advance and German retreat across France and Belgium in 1918 had begun to show some of the pace and aspects that would mark later mechanized warfare; British tanks played an increasing role, and German rear-guard defenses focused on stopping their advance. Although never implemented, Plan 1919 would have carried these trends forward earlier.
Background
By 1918, the British, French and German Armies had been through years of trench warfare and were approaching their breaking point. Both sides realised that a new form of warfare was needed for the successful conclusion of the war. Tanks, although used unsuccessfully at the Battles of the Somme and Passchendaele, were used in the Battle of Cambrai and demonstrated their usefulness. Although the main objective was not achieved, and the German artillery made short work of them after the initial shock had worn off, military theorists were inspired to try to incorporate them properly.
In the spring of 1918, J.F.C. Fuller submitted a study, "The tactics of the attack as affected by the speed and circuit of the Medium D tank", a bold new plan involving tanks and air support that aimed to target the German leadership and supply lines, as opposed to the tactic then used of grinding away at the main forces.
Fuller's plan had three elements. The first was a fast attack by medium tanks and aircraft against the German headquarters, removing its ability to control their forces. Then, the main assault by heavy tanks, infantry and artillery would break the German lines. Finally cavalry, light tanks and infantry mounted on trucks would follow the retreating Germans to prevent them from reforming or counterattacking.
His plan was to be used as the blueprint for the spring offensive the next year and was titled "Plan 1919". The German armistice in November 1918 precluded the implementation of the plan, but it was studied extensively by the Germans and used as the model for their Blitzkrieg attacks during the next war (Fuller). Plan 1919, although never carried out, laid the "groundwork" for numerous upgrades in military equipment, technology and tactics of modern warfare .
Fuller's ideas were largely in line with papers put forward by other members of the Tank Corps such as by Capper and Elles' paper "The future of tank operations and production requirements", which envisaged tank forces of several thousand light, medium and heavy tanks and the means and the time necessary to produce them and then to deploy them to the front.
Description
Fuller, in his Military History of the Western World stated, "There are two ways of destroying an organization: 1. by wearing it down, 2. by rendering it inoperative. In war the first comprises the killing, wounding, capturing and disarming of the enemy's soldiers- body warfare. The second, the rendering inoperative of his power of command- brain warfare. To take a single man as an example: the first method may be compared to a succession of slight wounds which will eventually cause him to bleed to death; the second- a shot through the brain".
