The armies of Nazi Germany crossed the border with Austria, but when Hitler arrived in Vienna just 2 days later, the very first thing he did was to go to the Hofburg museum to lay claim to what appeared to be a simple Roman spear head. This spear head was something that Hitler had apparently coveted ever since he had first nurtured ambitions to become the ruler of a new German Reich. After the end of the Second World War, the lance was lost. Walter Horn, a US Army lieutenant who had fled Germany, went in search of the Holy Lance.
