Answer:
Option C, It allowed the Union Army to have total control of the Mississippi River, is the right answer.
Explanation:
During the Civil war, the battle of Vicksburg was one of the major victories of the Union. This battle took place between 18th May 1863 until July 4, 1863. In this battle, the Union forces were led by commander General Ulysses S. Grant while the Confederate forces were led by General John Pemberton. The outcome of the battle can be seen in the fact that the Union Army established its total control over the Mississippi river.
The correct answer is manifest destiny.
Manifest destiny is the belief that it was America's god given right to expand from "sea to shining sea." In other words, it was America's destiny to expand their control across the entire North American continent from the Atlantic to the Pacific Ocean. This belief resulted in the US buying land from other countries, fighting in wars, and taking land from Native Americans in order to achieve this goal. This was present throughout American society during the early to middle of the 19th century.
