On 26 January 1915, the representatives of the German ministries for foreign affairs and also war, general headquarters and navy headquarters had made a decision to provide military training for 200 Finns. The commander was major Maximilian Bayer, who was a war veteran from the German African colonies and the chairman of the German Scout league, "Deutsche Pfadfinderbund", which he established in 1907 and of which he served as the chairman, "Reichsfeldmeister". In World War I, he had served in the Regiment Prinz Louis-Ferdinand, the 27th Infantry Regiment, and took part in the attack against Liège in Belgium. Thereafter, he had served as the German commandant of Liège from 5 January 1915. The original idea was to nominate the commander, one infantry captain and one pioneer captain, but the decision was to nominate four captains: Julius Knaths, Hans Bade, Walter Just and Karld Heldt. They all reported to the German Ministry for War on 13 February for instructions. In April 1915, Offiziersverstellvertreter Hans Eller was also ordered to the Pathfinder course, for machine gun training. From 12 to 13 non-commissioned officers were ordered to attend the course, and also six pioneers. The master sergeants ("Fäbel") were Perper and Steinmuller, and the non-commissioned officers in lower ranks ("Unteroffiziers") were Claussen, Huyssen, Hoden and Toeppel. Hoden and Toeppel were assigned to other duties later. The pioneer non-commissioned officer Claussen and machine gun trainer Huyssen continued to serve during the 27th Battalion period and became lieutenants.
