EVERYONE knew SHE was watching the BEAUTIES How the guards of the ss camps answer for everything

When Bat-Sheva Dagan first began her duties inside the hellish confines of Auschwitz, she was supervised by SS guards led by a young Nazi officer named Franz Wunsch.

Given his position in charge, it wasn’t immediately clear why he spent so much time on the processing floor. But he’d pace the area where Dagan and other Jewish women worked, sorting through the suitcases that had been unloaded from trains bringing in tens of thousands of people to meet their deaths at the camp.

Soon, however, the Polish teenager became suspicious of Wunsch’s motives. She often spotted the otherwise taciturn officer in conversation with Helena Citron, her fellow prisoner and co-worker.

“He would speak to her and nobody else,” Dagan told The Post. “I watched from a distance, but it looked like they had something between them.”

As impossible as it sounds, the two were carrying on a forbidden romance forged in the shadows of the gas chamber.

Dagan and others who caught on to the situation struggled to fathom how Citron, torn from her homeland in Slovakia to live at the mercy of the Third Reich, could entertain the idea of ​​getting involved with one of its servants.

The taboo relationship between Wunsch and Citron is now the focus of the film, “Love It Was Not” (out Friday). The documentary doesn’t pass judgment and strives to present an unbiased account of the controversial affair that lasted more than two years.

Director Maya Sarfaty embarked on the project after hearing about the courtship from her then-acting instructor, Miki Marin, a favored niece and confidante of Citron, who died in 2007.
