After several attempts at the Nanga Parbat, Aufschnaiter led a small four-man expedition in 1939, including Heinrich Harrer, to the Diamir Face with the aim of finding an easier route to the peak. Having concluded that the face was viable, they were in Karachi at the end of August waiting for a freighter to take them home. The ship being long overdue, Harrer, Ludwig and Lobenhoffer tried to reach Persia with their shaky car, but several hundred kilometers northwest of Karachi were put under the protection of British soldiers and escorted back to Karachi, where Aufschnaiter had stayed on.
