Interbellum

After the war ended, he was attached to the staff of the Third Silesian Uprising as the commander of intelligence services. In 1923 he was sent to Tokyo, where he organized course of radio intelligence for Japanese officers. For his efforts in this area he was awarded Order of the Rising Sun - the highest military award in Japan. In 1928 he graduated from the École Supérieure de Guerre in Paris and was promoted to the rank of Major. Although not directly involved in radio intelligence any more, he remained a Polish intelligence officer. From 1929 he served as a military attaché at the Polish embassy in Moscow, but in 1933 he was declared persona non grata and moved to a similar post in the embassy in Bucharest, where he remained until 1937. Upon his return to Poland he briefly headed one of the branches of the Obóz Zjednoczenia Narodowego political organization and became the director of TISSA company, a Polish intelligence-sponsored company importing rare materials for the Polish arms industry. He was also promoted to Lieutenant Colonel.
