After Nazi Germany surrendered in May 1945, General Arnold ordered Crump to document the extent of the damage caused by aerial bombardment. This project was code-named "Special Film Project 186." Crump and his crew, using color film, surveyed bomb damage inflicted on the major European cities. In addition, Crump recorded the debriefings of Nazi civilian and military personnel in Allied custody such as Hermann Göring, as well as the capture of the Ohrdruf and Buchenwald concentration camps by American soldiers. Upon viewing the film of the camps for the first time, Malvin Wald recollected, "Even though it was a summer day, Reagan came out shivering—we all did. We’d never seen anything like that."
