After some study I found out this photo was taken before the Gelbe Kaserne in Aachen. The Gelbe Kaserne is not there anymore but was located at the corner of the Düppelstraße / Elsasstraße. These german soldiers surrender at the Düppelstraße.
It would not surprise me if the trees still the same as in the old photo.
