The effect of the action at Shimonoséki on the position of foreigners was at once made apparent in various ways. The Tycoon's Government had laid a secret embargo on raw silk sent to market at Yokohama as part and parcel of the general imperial design of closing that port, or, in the alternative, of a gigantic scheme of Government monopoly of the whole foreign trade, such being the only form of commerce for which the Japanese officials had any real sympathy. The stoppage had lasted three months. After Choshiu's defeat the restrictions were at once officially withdrawn, though considerable efforts were still required to give full effect to the withdrawal. Once more, also, "the Tycoon resolved to abandon the policy of equivocation and duplicity," and to inform the Mikado frankly of the impossibility of closing the port or of refusing to maintain the treaties.
The moment seemed opportune for raising the question of the ratification of the treaties by the Mikado, in respect to which Sir Rutherford Alcock made certain plain statements in a letter addressed to the Tycoon in person. "There exists," he said, "a want of accord on the subject of foreign relations between the Mikado and Tycoon.... The Mikado, by requiring the abrogation of treaties, has reduced the Tycoon to the alternative of either disobeying his legitimate sovereign or bringing on his country all the calamities of war.... The only solution of the difficulty that promises either peace or security is the ratification of the treaties by the Mikado." The four foreign representatives simultaneously pressed the same consideration on the Government, eliciting from the Japanese Ministers the admission, "We perfectly agree with you, it should now take place."
It now became the business of the British Minister to show to his Government that the proceedings at Shimonoséki fulfilled in every point the instructions he had received from the Foreign Office. This he did in a despatch dated September 28, 1864, and so convincingly that Earl Russell wrote in reply--
Your despatch of the 28th of September is a successful vindication of the policy you have pursued.... My despatches of the 26th of July were written with a view to discourage the interruption of a progressive trade by acts of hostility, and to forbid recourse to force while the treaty was generally observed. Those despatches, you will understand, remain in full force.
