Owing to the opening of seaports in Northern China for foreign trade in 1842, the growing Russian influence in the Northern Pacific and many other circumstances caused England to perceive the necessity of having a naval depôt and commercial harbour on the Tong Hai and on the Yellow Sea. England was doubtless casting her eyes upon the Chusan Island or some other island in the Chusan Archipelago, but did not dare to occupy any one of them lest she should thereby offend the chief trading nation of that quarter, viz., China. However, in 1885 England annexed Port Hamilton, on the southern coast of the Corea, during the threatened breach with Russia on the Murghab question. “Port Hamilton,” said the author of “The Present Condition of European Politics,”[6] “was wisely occupied as a base from which, with or without a Chinese alliance, Russia could be attacked on the Pacific. It is vital to us that we should have a coaling station and a base of operations within reach of Vladivostock and the Amoor at the beginning of a war, as a guard-house for the protection of our China trade and for the prevention of a sudden descent upon our colonies; ultimately as the head station for our Canadian Pacific railroad trade; and at all times, and especially in the later stages of the war, as an offensive station for our main attack on Russia.” Port Hamilton forms the gate of Tong Hai and the Yellow Sea; it cannot, however, become a base of operations for an attack on the Russian force at Vladivostock and the Amoor unless an English alliance is formed with Japan. The above writer shows an ignorance of the importance of the situation of Japan in the Pacific question. Japan holds the key of the North China Sea and Japan Sea in Tsushima.[7] She has fortified that island, and placed it in direct communication with the naval station of Sasebo, also with the military forces of Kumamoto. She also can send troops and fleets from the Kure naval station and the garrison of Hiroshima. She would also, if required, have other naval stations on the coast of the Japan Sea ready for any emergency. In this manner she would be able to keep out the British fleet from attacking Vladivostock and the Amoor through the Japan Sea. Even if she might not be able to do this single-handed she certainly could by an alliance with Russia. If also Japan occupied Fusan, on the south-eastern shore of the Corea, the Japan Sea would be rendered almost impregnable from any southern attack. Again, Port Hamilton would be useless as a head station for the Canadian Pacific Railway trade without an Anglo-Japanese alliance. If you look at the map, you can easily appreciate the situation. Japan, with many hundreds of small islands, lies between 24° and 52° in N. lat., its eastern shores facing the Pacific and cutting off a direct line from Vancouver’s Island to Port Hamilton. It must therefore depend mainly upon Japan as a financial and political success.
