finishing the following day; the corps then camped for several days near Chambersburg, Pennsylvania. The First Corps divisions of Hood and McLaws were far from Cashtown and would not arrive in time to partake in the first day's fighting on July 1, while Pickett's division was even farther back, being left to guard the lines of communication through Chambersburg, and would not rejoin the army until late on July 2. Meanwhile throughout this first day of battle units of the Second and Third Corps (about a third of Lee's army) pushed both Union I and XI Corps (about a fourth of Meade's army) back through Gettysburg, despite stubborn resistance by John Buford's Federal cavalry and initially the infantry as well. As the rest of the Union army came up it joined the two battered corps on the defensive line being constructed along much of Cemetery Ridge.

On the third day Pickett's diminished division, finally arrived, and two small division from the Third Corps attacked the center of the Union lines near Cemetery Ridge.
