In 1943, Jaeger was approached and reluctantly agreed to the plans for an attempt on Hitler's life. Owing to his Christian convictions, he would rather have seen Hitler standing before a duly constituted court. Jaeger's son was a Captain in the "Gross Deutschland" Division, one of Germany's most elite units. Jaeger's son Krafft was arrested and charged with attempted treason and leading a comrade into military disobedience. Krafft was freed for lack of evidence, but he was then sent back to the front so that he could "recover his honour".
