After the fall of Paris Schilling requested transfer from the Army back to civil service, and in October of the same year he returned to Foreign Affairs in Saint Petersburg. Russian foreign policy of the immediate post-war period concentrated on eastward expansion, thus Schilling was placed with the growing Asiatic Department. He continued to take an interest in electricity and lithography, a new method of printing which he wished to introduce into Russia. His presentation of the latest German lithographic printing technology aroused interest in the Ministry, and very soon he was dispatched back to Bavaria, with instructions to secure supplies of lithographic stone from the Solnhofen quarries. In July 1815 he arrived in Munich to meet with Alois Senefelder, the inventor of the lithographic process, who assisted Schilling with his errand; in December Schilling briefly visited Bavaria again, to take delivery of finished stones. During 1815 he met many French and German orientalists and physicists, particularly André-Marie Ampère, François Arago and Johann Schweigger.
