Explanation:

The siege of Vicksburg by the U.S military troops took about a year from 1862 to 1863. There were multiple cases of continuous conflict and bloodshed in the attempt of capturing Vicksburg.The surrender of the Vicksburg can be attributed to the lack of food and clean drinking water in the city.
