Placing him into the military structure was not easy. Schilling did not have any combat experience. As a retired Army officer, he was merely a second lieutenant (podporuchik); as a civil servant, he has reached a rank equivalent to Army major. The situation was not uncommon for the volunteers of 1812, yet it had puzzled military authorities and Schilling's application was rejected. In May 1813 he appealed directly to Alexander I, who authorised placing Schilling to horse artillery reserves; on he was posted to Alexander Seslavin's 3rd Sumskoy dragoons with the rank of "Stabs-rotmistr" (equivalent to infantry "staff captain") Schilling arrived at the regiment shortly after the Battle of Dresden. He was initially employed as a liaison with Saxon authorities, and had not seen real combat until December 1813, when Russian troops advanced into French territory. He received his first combat award for the Battle of Bar-sur-Aube of 27 February 1814; his actions during the Battle of Arcis-sur-Aube and the Battle of Fère-Champenoise were rewarded with the Golden Weapon for Bravery.
