We reached the Buchenwald Memorial Archives where Dr. Lake Mackenzie , previously contacted, allowed us to scan numerous folders containing material on musical activity in the Buchenwald camp up to April 1945.

The musical diary of Polish musician and writer Jan Pribula , who had been deported there, needed to be scanned; the diary is bulky and scanning it would have taken too long, which is why Mackenzie gave us a USB stick with Pribula's diary already scanned in high definition.

The trip to Buchenwald concluded with a visit to the camp and photographic documentation of the site.

The next day we reached Frankfurt by train and Krakow by plane; Christof Kulisiewicz was waiting for us to deliver the manuscript of the song Le Crucifié, written in 1944 in Sachsenhausen.

Le Crucifié is the most important and precious musical manuscript written in a concentration camp during World War II; it was written on two pieces of cardboard stuck together.
