The same year, Kilbom was asked by Bukharin to go to Germany as a representative of the Communist International to overlook the development of the Communist Party of Germany. Kilbom had been to Germany on political missions several times and the German police had started to recognize him. Because of this, Kilbom was now denied a visa by the German embassy in Stockholm. He decided to take the train to Copenhagen, where he made a new attempt at the German embassy in Denmark. He was denied a visa once again, but instead he managed to get help from some sailors and was smuggled on board a boat that took him to Germany. There he was greeted by Willi Münzenberg, who bought him a new suit and provided him with a fake passport with the name Karl Derry. He spent over three months in Germany and Austria, working to eliminate the ultra-leftist factions within the Communist parties.
