The story was made into a 1975 film Dersu Uzala, directed by Akira Kurosawa.
Dersu Uzala (c. 1849–1908) was a Goldi hunter who acted as a guide for Arsenyev's surveying crew mapping the taiga from 1902 to 1907 and saved them from starvation and cold.
In the spring of 1908, Dersu bade farewell to Arsenyev and walked back toward his home in the woods of the Primorsky Krai; he was killed before he could reach them, near the town of Korfovskiy, evidently for the highly valuable latest model Russian military rifle given to him by Arsenyev as a parting gift to replace his old, worn, Berdianka.
He was buried in a hastily dug grave, unmarked but for Dersu's walking stick, stuck in the earth beside it by a heartsick Arsenyev.
It appears that the Dersu character is a composite of several trappers who Arsenyev met during his expedition.
