During the German-Soviet war, Krzeptowski tried to recruit volunteers for his "Goralen legion" (also referred to as Goralische Division SS) to fight alongside the Axis Powers. The attempt ended in a complete fiasco as out of the initial 300 able bodied recruits (from the entire Podhale region) all but twelve deserted within a short time or were sent to concentration camps by the Germans for insubordination. At the end of the war, he refused to flee to Germany and instead hid out in the Tatry mountains of his native region. In December 1944 he was tracked down and captured by the Home Army. He was tried for high treason, sentenced to death by hanging, and executed by his own brother, Julian Krzeptowski, a Home Army member.
