MARCUS OTTERBOURG, United States Consul to General Thomas O’Horan, Political Prefect, Mexico, June 10, 1867

Mr. Otterbourg to General O’Horan

The undersigned not being able to discharge efficiently, under his instructions, the duties which in the present circumstances the charge of the consulate and the archives of the United States legation in this capital impose upon him, finds himself, after a prolonged struggle against the situation and in his own despite, compelled to address to General Thomas O’Horan, political prefect, a request that he will have passports issued for the undersigned to leave the city with his family, accompanied by such American citizens and other persons entitled to the protection of the American flag who may wish, for reasons not unknown to his excellency the political prefect, to take advantage of the opportunity to withdraw from Mexico.

With assurances of high consideration,
