[3] Around 8 May 1945, Dollmann was protected from criminal prosecution of his involvement in war crimes by Cardinal Alfredo Ildefonso Schuster, Archbishop of Milan, with whom he had discussed the possibility for a separate peace between Nazi Germany and the Western Allies (Operation Sunrise).
Padre Parini helped him transfer to Spain, where he was employed by Otto Skorzeny in Donostia in the arms trade.
The Italian Intelligence Service issued false travel documents for Dollmann through Carlo Rocchi, a confidence man of the CIA in Milan.
Dollmann formed the basis for the character of Major Bergmann in the film, Rome, Open City (1945) by Roberto Rossellini.
He is also a character in the novel A Dark Song of Blood (2002) by Ben Pastor, set in Rome in 1944, and in Soviet TV-series Seventeen Moments of Spring (1973).
After the war, Dollman would maintain contacts with the CIA director Allen Dulles, as well as continuing communication with the Grand Mufti of Jerusalem Haj Amin Al-Husseini.
