When we continued our trip, we frequently noticed single horsemen far away or on the horizon, apparently studying our movements with care. All our attempts to approach them and enter into conversation with them were entirely unsuccessful. On their speedy little horses they disappeared like shadows. As we reached the steep and difficult Pass on the Hamshan and were preparing to spend the night there, suddenly far up on a ridge above us appeared about forty horsemen with entirely white mounts and without formal introduction or warning spattered us with a hail of bullets. Two of our officers fell with a cry. One had been instantly killed while the other lived some few minutes. I did not allow my men to shoot but instead I raised a white flag and started forward with the Kalmuck for a parley. At first they fired two shots at us but then ceased firing and sent down a group of riders from the ridge toward us. We began the parley. The Tibetans explained that Hamshan is a holy mountain and that here one must not spend the night, advising us to proceed farther where we could consider ourselves in safety. They inquired from us whence we came and whither we were going, stated in answer to our information about the purpose of our journey that they knew the Bolsheviki and considered them the liberators of the people of Asia from the yoke of the white race. I certainly did not want to begin a political quarrel with them and so turned back to our companions. Riding down the slope toward our camp, I waited momentarily for a shot in the back but the Tibetan hunghutze did not shoot.
