Mata O'hara

Mata O'hara was the sobriquet which historian James P. O'Donnell assigned to Hermann Fegelein's mistress.

In his book, "The Bunker", O'donnell wrote that this woman was of either Irish or Scottish descent and married to a Hungarian diplomat stationed in Berlin, who was arrested after Hungary's occupation by Germany. She was also a British agent.

Fegelein met her during the summer of 1944, at a party held in Goebbels' villa. After she became his mistress, Fegelein arranged for her to stay in a house located at Bleibtreustraße 11, Berlin.

After Heinrich Himmler's attempts to negotiate with the Allies were discovered by Hitler, he ordered the SS to bring in Fegelein. According to O'Donnell, A detail headed by officer Helmut Frick arrived in the residence, but Fegelein assured them he would come of his free will later. When a second detachment, commanded by Obersturmbanführer Peter Högel, came with explicit orders to arrest Fegelein, his mistress had already fled.

Der Untergang
The historical details of the arrest were simplified in the film, and it shows only Högel (portrayed by Igor Romanov) coming in and ordering his men to grab Fegelein, while the mistress (played by Marina Semenova) flees in panic.
