Good evening, this work here I find very interesting. Filibuster then,does not mean the same as today. I see great irony in our karmic penance here for the sins of our fathers. I know the United States could not have been great here at the time of this, because you had so many men wanting to make themselves Kings in foreign lands to our North, East and South. They never said anything about a wild South. Our ancestors were a restless bunch...

..Meanwhile, few filibusters departed southward from U.S. territory in the early 1840s, though transplanted Americans participated in the Texas Republic’s disastrous “Mier expedition” into northern Mexico in 1842 and some Americans got captured and executed in a foray from New Orleans to the Mexican state of Yucatán in 1844. Certainly no filibuster army materialized to answer the call of a Mississippi paper for “thousands of bold and adventurous spirits from ‘the States’” to conquer Mexico City’s treasures on behalf of the “Anglo-Saxon race.”28

Paradoxically, the Mexican War that erupted in the spring of 1846 both inhibited filibustering and guaranteed its revival. Now, on the one hand, adventurous Americans could satiate their filibustering inclinations by joining their country’s largely-volunteer army. Why participate in an illegal military venture, when one might invade foreign domains with the government’s blessing? On the other hand, the war’s end in 1848 created a pool of latent filibusters— conquering soldiers accustomed to military campaigning who dreaded being mustered out of the service (if they were volunteers) or being posted to routine peacetime assignments (if they were regulars).

In the months between the U.S. Army’s entry into Mexico City in September 1847 and the end of the war, some U.S. soldiers considered enlisting in an expedition to Yucatán, which had seceded from Mexico in 1846 and maintained neutrality during the fighting. Simultaneously, Cuba’s Havana Club (Club de la Habana), made up mainly of Creole merchants, planters, and professionals who favored the annexation of their island to the United States,29 took steps to enlist restless American war veterans in a rebellion to overthrow Spanish rule.

Trying to repress a bloody insurrection by Mayan Indians that erupted in 1847, Yucatán’s ruling elite unsuccessfully solicited the United States to assume a military protectorate over their state, and also offered $8 a month and 320 acres of land to American volunteers willing to soldier against the Indians. By the late spring of 1848, word was racing through U.S. forces occupying Mexico’s capital of this opportunity for continued military service. “There are officers in the city of Mexico trying to raise companies to go to Yucatan,” observed one of Pennsylvania’s volunteers on May 27. That same day, an American occupation newspaper instructed soldiers how they might sign up.30

At virtually the same time, the U.S. consul in Havana, Robert B. Campbell, informed the State Department of Cuban rebels’ hopes that “a few of the volunteer regiments now in Mexico” might “obtain their discharge” and join a revolution against Spanish rule that they hoped to initiate in the immediate future. Campbell’s information was accurate.
