C. S. N. meaning in Regional ?

Answer:

What is Confederate States Navy mean?

The Confederate States Navy (CSN) was the naval branch of the Confederate States Armed Forces, established by an act of the Confederate States Congress on February 21, 1861. It was responsible for Confederate naval operations during the American Civil War against the United States's Union Navy.

The three major tasks of the Confederate States Navy during its existence were the protection of Confederate harbors and coastlines from outside invasion, making the war costly for the United States by attacking its merchant ships worldwide, and running the U.S. blockade by drawing off Union ships in pursuit of Confederate commerce raiders and warships.

It was ineffective in these tasks, as the coastal blockade by the United States Navy reduced trade by the South to 5 percent of its pre-war levels. Additionally, the control of inland rivers and coastal navigation by the US Navy forced the south to overload its limited railroads to the point of failure.

The surrender of the CSS Shenandoah in Liverpool, England marked the end of the Civil War and the Confederate Navy's existence.
