In 1945 , Macher led a group of 15 SS specialists who were ordered by Himmler to blow up the SS castle Wewelsburg near Paderborn in order to ensure that the devotional objects and important files should not fall into the hands of the Allies . The demolition command arrived on March 31 , 1945 . The same day , after Macher had informed the local fire brigade , the south - east tower , the least important tower of the large castle , was blown up . Because of lack of explosives they could not blow up the rest of the complex . Macher ordered the firemen not to extinguish the fire so that most of the complex was nevertheless destroyed .

These treasures have never been found .

The three men were taken to an Allied barracks in Lüneburg on May 23 .
