In the mid-1950s, Wolters quarrelled with Kempf who effectively dropped out of the network for a number of years, adding to the burden on Wolters and Riesser. While Speer's pleas for his former associate and his former secretary to work together eventually brought about a healing of the breach, this was to some degree superficial as Kempf was aware that Wolters, even then, disagreed with Speer's opinions. Wolters questioned Speer's readiness to accept responsibility for the Nazi regime's excesses and did not believe Speer had anything to apologise for, though the strength of his feelings on this point was kept from Speer—but not from Kempf and Riesser.
