BALACHOWSKY: Yes. They wore a pink triangle to distinguish them.
M. DUBOST: Was the wearing of this triangle a well-established custom,
or on the contrary, was there much confusion in classification?
BALACHOWSKY: At the very first, before my arrival, from what I heard,
order was kept with respect to triangular badges; but when I arrived at
Buchenwald, in January of 1944, there was the greatest confusion in the
badges, and many prisoners wore no badge at all.
M. DUBOST: Or did they wear badges of a category different from their
own?
BALACHOWSKY: Yes, this was the case with many Frenchmen, who were sent
to Buchenwald because they were ordinary criminals and who finally wore
the red triangle of political prisoners.
M. DUBOST: What was the color of the triangle worn by the ordinary
German criminals?
BALACHOWSKY: They had a green triangle.
