This is a movie clip from a Japanese war film about the Battle of Tsushima in the year of 1905. It was the only gathering of two opposing fleets of dreadnoughts and was a colossal event of its time. It was fought over Korea in the sea of Japan. This movie should be released with English subtitles, but to my knowledge, it has not been done yet. The battle was fought between imperial Russia and the rapidly rising power of Japan. The events of this famous battle established Japan as a major sea power from 1905 onwards.
