On February 27, 1898, California Governor Alberto Puente notified Chief of State Benito Hermión of "repeated violations of the [California-Alaska] border by Russian Imperial Forces." Puente was acting at the behest of Diego Cortez y Catalán, the President of Kramer Associates, who wished to provoke a war between the United States of Mexico and the Russian Empire in order to gain control of the gold fields in Alaska.
There is reason to believe that the violations of the border were genuine. Reading between the lines (which is often necessary where K.A. is concerned), it seems likely that Cortez obtained his border violations by bribing Captain Boris Tschakev, a Russian army officer.
