Lewis D. Campbell to William H. Seward, May 15, 1867
Mr. Campbell to Mr. Seward
Sir: Mr. White, my special messenger to the government of the United Mexican States at San Luis Potosi, returned to this city to-day. He was made the bearer of a despatch addressed to me by his excellency Señor S. Lerdo de Tejada, minister of foreign affairs, a translation of which I have the honor to transmit herewith.
Mr. White arrived at San Luis Potosi on the 21st ultimo. He remained there two days, and on the 23d started back. He reports the following information in regard to Mexican affairs. Maximilian still held Queretaro with a force estimated at 15,000, and was besieged by a liberal force of 30,000, which was being re-enforced. All the roads from the city except one were occupied by the liberals. It was understood at San Luis that the imperialists were still in possession of Vera Cruz and the city of Mexico. He also learned from President Juarez that he confidently expected to be able to enter the city of Mexico in three or four months.
I have had a short interview only with Mr. White, and must close this despatch now to be in time for the mail. Should I derive from him further items of information, I will communicate them to you to-morrow.
I have the honor to remain your most obedient servant,
Hon. William H. Seward, Secretary of State, Washington, D. C.
