to cut off the north and the south
the plan for the liri battle was to defeat Rome
Grant put the city of Richmond under siege by essentially surrounding it and cutting off any supply route. The above answer requires more detail. In the Spring of 1864 Grant devised a strategy to cut Richmond's supply lines from the South. Five railroads led from the city of Petersberg to Richmond, Grant's plan was to destroy these and Richmond would surely fall. This strategy was placed in jepoardy and Richmond would live to see another day.
General US Grant had assigned over 30,000 troops to be under the command of Major General Benjamin F. Butler. Grant' s plan closely resembled the strategy of former General George B. McClellan. Butler would ascend to the James River in Virginia and land to the south of Richmond. Grant believed that Butler's army could easily defeat the small Confederate force left to defend Richmond. Butler was expected to cut Richmond's lines of supply and communications that led to the south of the city. If for some reason Butler could not capture Richmond, he would at least cut off its lines of supply and communications and place the city under siege.
Major General Ambrose Burnside's plan to defeat the confederate army at Fredericksburg, VA failed and ended in a bloody defeat for Grant's Union Army. Burnside was relieved of his command a month later.

The Anaconda plan
General Grant planned to capture Vicksburg because if he succeeded, the United States would be one step closer to executing their plan to defeat the Confederate States. The US had a plan known as the Anaconda Plan to defeat the Confederate States. Their plan was to blockade Southern ports, seize control of the Mississippi River to split the Confederacy in half, and attack the Confederacy from all sides to surround them. General Grant's plan to capture Vicksburg complies with the seizing of the Mississippi River to split the Confederacy in half.
With Lieutenant General US Grant using his Overland campaign against the forces of General Lee, Grant wanted to insure the safety of Washington DC. Grant's plan was to have Major General Franz Siegel to join forces with Brigadier General George Crook who was advancing from West Virginia. Together, there would be 15,000 troops. Grant believed that these combined infantry forces plus a large cavalry force was enough to discourage Confederates in the Shenandoah Valley from menacing Washington DC.
Confederate President Jefferson Davis promised in his speech in December 1862 to capture the border state of Missouri. This objective became the main goal of General Johnston when he was assigned to command the Western Department. The Union obstacle to bring Missouri into the Confederacy was the army of Union General US Grant. His forces lay east of the Mississippi River and divided Confederate armies west, south and east of him. Johnston's plan was to defeat Grant by using troops from Vicksburg and the Trans-Mississippi Department and his own, to advance on Grant from two directions and defeat him. If that could be accomplished, he believed the way would be open for Confederate General Holmes to advance into Missouri. Missouri being a slave owning border state was filled with Southern sympathizers, including its former governor. Controlling Missouri and controlling the Mississippi River city of St. Louis would cripple Union war efforts in the West immensely.

Peace plans were gaining momentum in the North and the South. The prospects for the ending the US Civil War, were still a question mark. General Robert E. Lee, had learned from General Longstreet, that General US Grant might consider a so-called "military convention" among the top generals on both sides to reach a peace agreement. Longstreet reportedly had learned for Union General Edward Ord, that Grant might be open for such a "convention". When President Lincoln learned of the plan, he instructed his Secretary of War, Edwin Stanton to inform Grant that there could be no such convention.
