In 1862, the Confederacy wins Antietam, and Britain and Spain recognize the Confederacy as a country, while France takes a bit longer to. Britain, France, and Spain all relied on the South for cotton. These were most commonly shipped for ports on the Atlantic, most commonly Charleston, Savannah, Norfolk, Wilmington, and more, and sometimes New Orleans from the Gulf of Mexico. The Confederacy also exported tobacco, sugar, and indigo.
Charleston Tea Party
On October 26th, 1862, a trade ship carrying cotton left from Charleston, South Carolina headed for Manchester. However, the Union were preparing to blockade the port of Charleston, in order to shut down the most important port on the Atlantic belonging to the South. This was a great strategy, but when they encountered a southern trade ship, they immediately shot at it. The sail of the ship had multiple bullet holes, but it was sunkenwhen cannons caused a hole through the boat, leading to it sinking.
Multiple Confederates in Charleston see the ship sink as it is very close to the port. They send a letter to Britain as well as British Canada, informing them of the sinking of this ship. Britain considers this as an act of war, and declares war on the Union. British Canada sends troops down and wins the Battle of Albany, and eventually leads to the US surrendering in the war.
The South began to call this the Charleston Tea Party because it was the key event that led to the Nationalism of its country, similar to the Boston Tea Party.
