Reenactment of the 1904 battle of the Yalu River

Ran into this interesting video on the LOC website. What we see is a reenactment of the 190 battle of the Yalu River. The battle lasted from 30 April to 1 May 1904, and was the first major land battle during the Russo-Japanese War. It was fought near Wiju (modern village of Sinuiju, North Korea) on the lower reaches of the Yalu River, on the border between Korea and China.

I am not sure what the purpose of the reenactment was, but here is what the source says about it:

KD: I understand that mistakes happen. But going through the description at the source it does appear that this video was produced prior to the actual battle. This video is listed as 1-4, H43618.
