In 1941/42 he was placed on the SS payroll in respect of his security services work and given a job at the Dresden command post: the work involved "scanning reports from about 28 so-called field offices", identifying points of significance in respect of commerce, agriculture, administration, transport and law. He then provided summary reports for Berlin. He received a "monthly stipend" of 250 marks for this work and at this stage was still able to undertake his own work as a lawyer. However, in 1943 he was moved to Berlin, recruited into "Amt VI" ("literally "Office 6""), the department that dealt with political foreign intelligence. He was told that his supervisor intended for him to be transferred to Switzerland, to work in an "intelligence capacity", but the transfer never took place, and he was based in Berlin till the war ended, in May 1945. It was probably in 1943 that Erwin Tiebel was introduced to Heinz Felfe, though since the two both came from Dresden it is entirely possible that the two of them had come across one another informally at an earlier date.
