This state of affairs could not continue. With the opening of the nineteenth century the ships of Europe began to make their way in large numbers to the North Pacific, and efforts were made to force open the locked gates of Japan. Some sought for food and water. These could be had at Nagasaki, but nowhere else, and were given with a warning to move on. In some cases shipwrecked Japanese were brought back in foreign vessels, but according to law such persons were looked upon as no longer Japanese, and no welcome was given to those who brought them. In other cases wrecked whalers and other mariners sought safety on Japanese soil, but they were held strict prisoners, and rescued only with great difficulty. The law was that foreigners landing anywhere on the coast, except at Nagasaki, should be seized and condemned to perpetual imprisonment, and that those landing at Nagasaki must strictly abstain from Christian worship. Meanwhile the Russians had become, through their Siberian ports, near neighbors of Japan, and sought to open trade with that country. In 1793 Lieutenant Laxman landed at Hakodate and travelled overland to Matsumai, bringing with him some shipwrecked Japanese and seeking for commercial relations with Japan. He was treated with courtesy, but dismissed without an answer to his demand, and told that he could take his Japanese back with him or leave them as he pleased. In 1804 the Russians came again, this time to Nagasaki. This vessel also brought back some shipwrecked Japanese, and had on board a Russian count, sent as ambassador from the czar. But the shogun refused to receive the ambassador or to accept his presents, and sent him word that Japan had little need of foreign productions, and got all it wanted from the Dutch and Chinese. All this was said with great politeness, but the ambassador thought that he had been shabbily treated, and went away angry, reproaching the Dutch for his failure. His anger against the Japanese was shown in a hostile fashion. In 1805 he sent out two small vessels, whose crews landed on the island of Saghalien, plundered a Japanese settlement there, carried off some prisoners, and left behind a written statement that this had been done to revenge the slights put upon the Russian ambassador. This violence was amply repaid by the Japanese. How they did so we have now to tell. In 1811 Captain Golownin, an intelligent and educated officer of the Russian navy, was sent in command of the sloop-of-war Diana to explore the Kurile Islands. These belonged to Japan, and were partly settled. At the south end of Kunashir, one of these islands, was a Japanese settlement, with a garrison. Here Golownin, having landed with two officers, four men, and an interpreter, was invited into the fort. He entered unsuspectingly, but suddenly found himself detained as a prisoner, and held as such despite all the efforts of the Diana to obtain his release.
