During the Gettysburg Campaign, Buford, who had been promoted to command of the 1st Division, is credited with selecting the field of battle at Gettysburg. On June 30, his command rode into the small town of Gettysburg. Very soon, Buford realized that he was facing a superior force of rebels to his front and set about creating a defense against the Confederate advance. He was acutely aware of the importance of holding the tactically important high ground about Gettysburg and so he did.
His skillful defensive troop dispositions, coupled with the bravery and tenacity of his dismounted men, allowed the Union I Corps, under Maj. Gen. Reynolds, time to come up in support and thus maintain a Union foothold at strategically important positions. The importance of Buford's leadership and tactical foresight on July 1 cannot be overstated in its contribution to the eventual union victory
