George Kennan and Richard Bush both wrote of the difficulties they encountered during the expedition. Kennan would later become notable for influencing American opinion of the Russian Empire. Originally very much for Russian settlement of the far East, on visiting the exile camps in the 1880s he changed his mind and later wrote "Tent Life in Siberia: Adventures Among the Koryaks and Other Tribes in Kamchatka and Northern Asia". Richard Bush, aiming to emulate Kennan's success, wrote "Reindeer, Dogs and Snowshoes".
