 Valland kept lists of all the works which came in, the secret storehouses where they were stockpiled when they left the museum, and the numbers of the train cars when the last of the paintings were shipped to Germany just before the Allied recapturing of Paris.Using Valland's information, the Resistance was able to delay the train sufficiently so that it never reached Germany.Although the ERR, in theory, was part of Alfred Rosenberg's Nazi empire, Rosenberg was an ideologue who had no interest in art, and did not appreciate the value to Germany of looting the patrimony of the occupied countries.
