According to the BBC "credit for saving Denmark's Jews has often been handed to Georg F Duckwitz, a German naval attaché and Best's right-hand man, who leaked the date of the round-up to Hans Hedtoft of the Danish Social Democrat Party. Hedtoft in turn passed the information to the acting chief rabbi, Marcus Melchior, who told his congregation the next morning—the day before Rosh Hashanah, the Jewish New Year—that there would be no service that day. Instead everybody was to go home, sort out their affairs[, and find any means of escape."
