Henry Wilson.
Henry Wilson was the chief Russian language translator at the United States of Mexico's State Department in 1898. Sobel raises the possibility that Wilson, a former employee of Kramer Associates, played a role in Diego Cortez y Catalán's scheme to provoke a war between the U.S.M. and Russia by mistranslating a telegram from Russian Foreign Minister Pyotr Sviatopolk-Mirsky to make it appear insulting and bellicose. After Wilson's translation of Mirsky's telegram was sent to Chief of State Benito Hermión, there was an escalating series of telegrams exchanged between the two men from March to May 1898 that ended with Hermión ordering extensive summer maneuvers by the Mexican Army, and sending the Mexican Pacific Fleet under Admiral Ephraim Small on a cruise to Hawaii. Before the month of May was out, the Great Northern War had broken out.
Sobel's source for Henry Wilson's actions is William Reilly's "Henry Wilson's Role in Initiating the Great Northern War" from The Journal of Russian Studies XXVII (June 1934).
