The "Krümpersystem", introduced to the Prussian army by the military reformer Gerhard von Scharnhorst, arranged for giving recruits a short period of training, which in the event of war could be considerably expanded. With this the reduction of the army's strength did not have the desired effect, and in the following wars Prussia was able to draw up a large number of trained soldiers. By the time of the Second Reich reservists were already being given so-called "war arrangements" following the completion of their military service, which contained exact instructions relating to the conduct of reservists in time of war.
