Question: Who was in charge of the country Ottwalt finally ended up in?

Living in Moscow, Ottwalt wrote for the German exile magazine Internationale Literatur (published by Johannes R. Becher) and was an editor at Vegaar Bibliothek. He also wrote for the Deutsche Zentral Zeitung. In 1936, he and his wife were ensnared in the Stalinist purges and arrested by the Soviet secret police, the NKVD. He was charged with suspicion of espionage, sentenced to forced labor and deported to a gulag near Archangelsk. His wife was sentenced to forced labor in Kotlas. She was deported back to Germany in January 1941 and didn't learn about his death until January 1958, when the Soviet Red Cross informed her that her husband had died on 24 August 1943.
