After the victory Chancellorsville, Confederate General Lee considered himself to be able to invade, for the second time in the Yankee territory. The goals pursued by this invasion were multiple (Trudeau, 2002):
A great victory in Yankee territory to force the Union to engage in peace negotiations,
Washington isolate and bring about the fall of the city by depriving supply rather than attacking its powerful front fortifications,
Advantage of the abundant resources of the northern states to supply an strong Southern army enduring hardships,
forcing the Union to withdraw troops from the western states where the situation was in Confederate degrading
At the end of May 1863, the Confederate Army of Northern Virginia, totaling 77,000 men divided into three parts (1 Longstreet's corps, the 2nd of Richard Ewell and AP Hill 3rd), left the sector Fredericksburg and crossed the Shenandoah Valley to enter the Federal territory.
In the camp northerner, the commander of the Army of the Potomac, Joseph Hooker, did not realize that Lee's departure nine days later.

Southerners, who expected to find in the locality reserve shoes were greeted by sporadic gunfire. Lee and Meade were at that moment away from Gettysburg and none of them had anticipated battle at this point. However, given the strategic importance of the city where 10 routes crossed, they decided everyone to send large reinforcements.
July 1
Southerners went for their first coordinated assault against Gettysburg on July 1. Significantly they launched a double attack against the city in higher number in the early hours of the battle. Further, Hill's corps was attacked by the West and specifically by the North Ewell.
