Mr. Romero to Mr. Seward

Dear Sir: I have the honor to remit to you copy of a letter from New York, dated the day before yesterday, in which various details are given of filibustering movements which are in preparation in that city for invading Mexico.

I am, sir, very respectfully, your obedient servant,

M. ROMERO.

Hon. William H. Seward, &c., &c., &c.

S. C. H. to Senor Romero,

Dear Sir: There was a meeting held at the New York Hotel last night, and from all accounts it was conducted with great secrecy. I, however have been able to learn these’ particulars, but I am informed that they have changed their tactics a little. The person who informed me is positively connected with the expedition, for he sailed last Saturday for Mobile. He was formerly attached to a New Jersey regiment.

The 1st division is to be made up of all nations, Germans, Irish, confederates, &c. Austin, Texas, is one of the rallying points of the expedition, and from here the avengers are to cross the Rio Grande in small detachments so as not to excite surprise or suspicion of the United States authorities on the frontier.

Who commands this movement I do not know, but I can find out by joining it. Allen is [Page 623] connected with it. At any rate Matamoras is where the first strike will be made. The 2d division is being recruited from the different German societies throughout the United States. One D’Utassi, late of the volunteer generals, and colonel of the Garibaldi Guard, is connected with this, also several of Sigel’s western officers and men, along with quite a number of Frémont’s and Blenker’s old division of the mountain department and the army of the Potomac.

St. Louis, Missouri, is the headquarters of this division. Quite a number of southern and ex-confederate officers are to join it from Nashville and Memphis, as it makes its way down the Mississippi to New Orleans. The rendezvous is Galveston, from whence they will be transported, with others, to Cape Rayo, and make way to Tampico, above Vera Cruz. The 3d and 4th divisions will be mostly southerners, although it is to receive recruits from different parts of the United States. This, from what I have learned, is the strongest and most to be feared part of the movement. Where they are to strike I am not very positive. I know this much: they have obtained transportation by water, and the movement is to be commenced from Philadelphia; Baltimore, Washington, Richmond, Norfolk, Virginia, are to furnish assistance. I think this portion of the expedition is to make its way out of Chesapeake bay in small fishing craft, &c., and connect with steamer outside on the Atlantic ocean. Men are also to reach them from Cape Hatteras via Raleigh, North Carolina, Charleston, Savannah, &c. St. Augustine, Florida, is a sub-rendezvous, from whence Vicksburg, Mobile, and the interior places are to forward material and men, and from whence they will be taken to Cape Sable, Florida, which is easily accessible from Nassau. Here at Nassau I am informed the filibusters have bought several ex-blockade-runners to transport themselves and Maximilian’s ex-officers, who are to leave Havana soon, say within 30 days, to some place (if not Vera Cruz itself) between Minatitlan, in the bay of Campeachy, or else Alvarado. This seems the most likely and gives color to to this plan:

1st. A movement across the Rio Grande to Matamoros to distract attention and draw away your Mexican army.

2d. While the 2d division effects a landing at Cape Ross and moves out to Tampico and San Luis Potosi, and awaits the 1st division to meet them, the 2d, while they make their way through from Matamoros to Victoria to San Luis Potosi: while this is being done the corps which have crossed the Gulf, and also having made a landing, will push Up on to Vera Cruz.

3d. While the 1st and 2d divisions move down to Queretaro, and then the 3d and 4th divisions try to close in on Mexico via Jalapa,

These I believe certainly are the intentions of the leaders. I may have made some mistake, but think I have written everything correctly. I am doing this work for nothing, and I hope Mr. Romero will either send me to New Orleans and let me work this affair according to my own notions, or else recompense me for my services. I advise you not to slight what I tell you; notify your government of this at once, or it will be regretted only when it is too late. The leaders are keeping very quiet now, because they were making too much excitement about the movement here. Baltimore is the headquarters. They have plenty of money, and are now being assisted by Englishmen, Frenchmen, Austrians, Prussians, and throughout all of Europe. If you can send me by the next steamer to Havana, I will be able to give you every information you desire, either by going directly to Vera Cruz, and so on to the seat of your government, or else telegraph you in cipher or write you by mail. Nothing is to be done for some 30 or so days; time is needed to make everything work smoothly for themselves.

Yours, &c.,

S. C. H.

Mr, Romero, Minister of the Mexican Republic, Washington, D. C.
