The battle you are referring to is actually called the Battle of the Ironclads. In this battle, it was the Merrimac (from the Confederacy) versus the USS Monitor (from the Union). This was the first battle between iron-fortified vessels in the Civil War. This battle ended up in a draw but represented a new form of fighting that both the Union and Confederacy had to be ready for.
Answer:
As the Union armies advanced through the Confederacy, thousands of slaves were freed each day until nearly all (approximately 3.9 million, according to the 1860 Census) were freed by July 1865. While the Proclamation had freed most slaves as a war measure, it had not made slavery illegal.
Explanation:
The war was lost by the Boer (white descendants of the colonialists) who until then had to independent republics, and those republics were placed under the British Empire. The war has left many Boers unsatisfied, and introduced a feeling of waiting for a future opportunity for an independence.
