Effects of Japan's Victory on the Yalu, 1904

From Rising Sun And Tumbling Bear, by R. M. Connaughton (Orion, 2020), Kindle pp. 90-91:

The battle of the Yalu was not only the decisive battle of this war, but was also a battle which ranks as one of the most important in the annals of warfare. The threat posed by Korea had been removed. Russia demonstrated her inability to go on the offensive, and her inability to match the fighting qualities of the Japanese at sea, and now on land. Russia had severely underestimated her enemy. The ‘monkeys’ had seen off her troops in a manner so impressive as to open the previously tied purse strings in London and New York to finance Japan’s further progress in the war. The psychological impact on Russia was immense; this disgrace was the beginning of her downfall, it was the beginning of many beginnings. From this point can be traced the inevitability of the end of the old colonialism, an impetus toward the development of world communism and its own attendant form of colonialism, and the euphoria which swept Japan into other wars, and the ultimate thermonuclear response. ‘The echoes of the battle will reverberate afar,’ wrote the military correspondent of The Times, ‘and distant is the day when the story will weary in the telling, among the races of the unforgiving East.’
