The Battle of Vicksburg. This Confederate city was the last impediment to the Union's control of the Mississippi River, and it was under siege for nine months before falling to the Union Army and Navy.
Major General Henry W. Halleck saw merit in the pre-war plans of the then Union general in chief, Winfield Scott. Halleck expected a Southern counter attack on General Grant's army at Pittsburg Landing. As the Union's commander in the Western Theater, he ordered the forces of General Buell to move down the Tennessee River and reinforce Grant. Anxious to control the Mississippi River, Halleck did not concentrate his entire force on the Tennessee River. Halleck kept General John Pope and an army of 25,000 troops west of the Mississippi, working with the Union navy, to capture Confederate strongholds there. He therefore, by his actions, agreed with Scott's idea of using the Mississippi River as a control point to keep as many Confederate forces as possible separated from each other.
