The Turning Point

In early June 1863 Robert E Lee took his army north. This was after a good year for the confederates with victories at Freidereksburg and Chancellorsville. By using the Shenandoah Valley and Jeb Stuarts cavalry to mask his movements. Lee army comprised three Corps: Ewell, followed by Longstreet and A P Hill.
By the 27th of June at his Maryland headquarters Hooker asked to be relieved of his command Lincoln immediately replaced Hooker BY George Meade. The next day Meade learned that A.P.HILL and Longstreet are east of Chambersburg en-route to Gettysburg he orders three corps to the outside of Emmitsburg. On the 30th of June the Union cavalry under Buford’s lead enter Gettysburg. Buford soon realised that confederate infantry brigade had occupied the town but minutes earlier had withdrawn after observing the Union approach. Buford halted for the night and posted two brigades on the Chambersburg road Northwest of the town
