In July 1854, the thriving port of Greytown (San Juan del Norte) on the Mosquito Coast was leveled to ashes by the U. S. Navy sloop-of-war USS Cyane.
The escalation stemmed from an absurd chain of petty grievances. Tensions began when American transit company owner Cornelius Vanderbilt clashed with local authorities over trade monopolies. Matters reached a boiling point when an American captain accidentally killed a local pilot, prompting a crowd to surround U.
S. Minister Solon Borland, who was hit with a thrown bottle fragment during the melee. Demanding an official apology, compensation, and a formal gun salute to the American flag, the U.
S. government dispatched Commander George Hollins. When local authorities refused to offer the formal salute, misinterpreting the demand as extortion from an illegitimate fleet, Hollins issued an ultimatum.
Receiving no compliance, he ordered a full bombardment on July 13, 1854, followed by a landing party that burned down the remainder of the town. International outcry was swift, but President Franklin Pierce defended the action, marking a dark chapter in gunboat diplomacy.
