Marius Fiil, owner of the Hvidsten Inn and leader of the Hvidsten Group, met with Giesler on 12 March 1943 following an SOE drop the night before on Trinderup Heath east of Mariager that had delivered 12 to 14 containers of explosives and weapons to supply the resistance in Jutland.

That evening, Fiil, with the help of his neighbour Andreas Stenz, retrieved the weapons and eventually brought them to Mustard Point, which was chosen by the Hvidsten Group as a receiving site and became one of its most reliable during the resistance effort.

[citation needed] The Hvidsten Group received many drops during the resistance signalled via "greetings" at the end of the BBC news broadcasts with the encoded message "Greetings to Elias - Listen again" and delivered via British Halifax planes.

Six months later, the January 1945 issue of the resistance newspaper Frit Danmark (Free Denmark) reported that on 29 June the previous year Fiil and seven other named members of the Hvidsten group had been executed.
