 On 18 October 1941, Anatoly Gurevich was ordered by Leopold Trepper to drive to Berlin to find out why the group were no longer transmitting.Trepper had received a message on 26 August 1941 with a set of instructions for the Schulze-Boysens, Harnacks and Kuckoff's, to re-establish communications.Although it took several weeks for Gurevich, travelling under the pseudonym of Victor Sukolov, to reach Berlin, the visit was largely a failure and the groups remained independent.
