American Legal

It was a war that saw many firsts. The long list of Civil War firsts include America's first income tax, the first battle between ironclad ships, the first extensive use of black soldiers and sailors in US service, the first use of quinine to treat typhoid fever, America's first military draft, and many others. There were advances in medical treatment, military tactics, the chaplain service, and other fields. Over the course of the Civil War, weapons ranged from obsolete flintlocks to state-of-the-art repeaters.

By the early 19th century, several European nations had banned slavery, but while the United States had banned the international slave trade, slavery was still legal in the country itself. As a result, there was still a strong financial motive for merchants and slave traders to attempt to bring slaves to the Western hemisphere, and a lot of profits to be gained from successfully sneaking slaves into the American South and the Caribbean by way of locations like Havana, Cuba.
