The USS Mercedita, a Union steam gunboat, returned to New York yesterday after eight months of aggressive service in the Gulf of Mexico, bringing with it a stunning haul: over $1.6 million in captured Confederate cargo and blockade-running vessels. Commander Henry S. Stelhwagen's ship earned itself the title "The Terror of the Gulf" by seizing three vessels off Abaco, including the notorious British steamer Bermuda—a capture that has ignited fierce legal controversy. The Mercedita also played a crucial role in bottling up New Orleans by stationing off Pass-à-l'Outre with the gunboat Winona, preventing Confederate supply vessels from escaping with valuable cargo. But the paper's extensive Key West correspondence reveals the war at sea is far more complicated than simple Union victories: British neutrals are protesting the Bermuda's capture as illegal, Confederate blockade runners like the fast steamer Nashville continue to slip through Union nets, and theft and bribery threaten to undermine prize adjudication itself.

By August 1862, the Civil War had shifted from a land campaign to an economic stranglehold. The Union's Anaconda Plan—strangling Confederate commerce through blockade—was becoming the war's central strategy. Every captured merchant vessel, every bale of cotton intercepted, every munitions shipment destroyed represented Union pressure on Southern supply lines. Yet the paper reveals the friction point: Britain's maritime law and neutrality claims clashed directly with Union blockade enforcement. The Bermuda case wasn't just about one ship—it threatened to drag Britain into the war on the Confederate side if pushed too far. Meanwhile, Confederate blockade runners were becoming faster and more daring, turning Caribbean islands like Nassau into shadow ports of supply. This was 1862's hidden war: not armies clashing, but commerce, law, and international politics colliding on the water.

• A discharged English soldier named Thomas McRae was arrested at Key West for stealing critical legal papers from the Prize Commissioner's office—papers necessary to condemn a captured British steamer. He was discovered 'in close converse with the captain' and is suspected of being bribed 'a good round sum' to destroy evidence. The correspondent despairs that the papers will 'never be found.'
• The rebel steamer Reliance, captured by the USS Huntsville, was an old river boat so underpowered that it could only raise 40 pounds of steam pressure (half its normal 140 pounds) at the time of capture—the only reason the Union gunboat could catch it. The correspondent notes it would sell well in New Orleans as a towboat but is nearly worthless in the North.
• A British naval sloop-of-war called the Petrel departed Key West 'destination unknown,' and the correspondent writes with visible relief: 'We part with our English visitors without regret, and humbly trust that no more of them will enter the harbor of Key West.' The undertone of anxiety about British intervention is unmistakable.
• Salt—not weapons or cotton—was a crucial cargo. The captured schooner Orion was carrying 150 sacks of salt when seized, along with drugs, tin, and nails. Salt was essential for preserving meat and fish for the Confederate army, making even mundane cargo strategically vital.
• A single marshal's auction sold a captured slave bark for only $2,791—'about half their value'—showing how flooded the market had become with Confederate prizes. The bark Pilgrim was simultaneously loading 500 bales of cotton for New York, with more shipments promised imminently.

• Commander Henry S. Stelhwagen of the USS Mercedita would become one of the Union Navy's most celebrated blockade officers—his name appears three times on this front page alone, cementing his reputation as the man who made British merchants fear the Gulf Coast.
• The Bermuda case split legal opinion dramatically: British lawyers argued she was captured illegally within British waters near Abaco, while the Union correspondent claims precise compass bearings prove she was 'a long distance' outside English jurisdiction. This dispute nearly became a diplomatic incident—exactly the kind of friction that threatened to pull Britain into the war on the Confederate side.
• The fast steamer Nashville, mentioned repeatedly as uncatchable, became so notorious that Union commanders were desperate enough to ask whether *any* existing blockade vessel could outrun her. She would famously run the blockade at Dobey Sound repeatedly, causing Nassau merchants to laugh at Union efforts—a humiliation the correspondent finds intolerable.
• The paper notes that more captured cotton now reaches Key West than successfully reaches Nassau—a stunning reversal suggesting the blockade was finally working by mid-1862. Yet thousands of bales still lined the South Carolina and Georgia coasts, waiting to run the gauntlet.
• A discharged soldier from the First Regiment United States Artillery stole prize papers to help a British captain—a reminder that loyalty was never guaranteed, and that war profiteering and bribery were as real as cannon fire.
