The quote was, "I never saw another butterfly"- it was a line written by a a survivor of the Teriz Jewish Ghetto (Inge Auerbacher). It is truly heartbreaking, especially in the context of the film, and I wanted to post the poem ("The Butterfly") here:
The last, the very last,
So richly, brightly, dazzlingly yellow.
Perhaps if the sun's tears would sing
against a white stone.
Such, such a yellow
Is carried lightly way up high.
It went away I'm sure because it wished to
kiss the world good-bye.
For seven weeks I've lived in here,
Penned up inside this ghetto.
But I have found what I love here.
The dandelions call to me
And the white chestnut branches in the court.
Only I never saw another butterfly.
That butterfly was the last one.
Butterflies don't live here,
in the ghetto.
