CSPAN 3 is running a number of Gettysburg related programs today. Gettysburg Times summary of the events of June 30, 1863:
Early on the morning of June 30, 1863, Union cavalry General John Buford rode into the crossroads town of Gettysburg with two brigades of horseman numbering approximately 3,000 troopers. He was joyously received by the local citizens, who had less enthusiastically hosted Confederate General Jubal Early's infantry on June 26. "Men, women and children crowded the sidewalks and vied with each in demonstrations of joyous welcome." General Buford established his headquarters at the Eagle Hotel, the current site of a convenience store at Chambersburg and Washington Streets.
West of Gettysburg, in Cashtown, General A.P. Hill positioned his Confederate infantry corps. Generally, cavalry preceded infantry on scouting missions, but in this instance, General J.E.B. Stuart's cavalry was elsewhere. Therefore, J. Johnston Pettigrew's brigade of approximately 2,700 North Carolinians had to conduct a scouting mission towards Gettysburg on the Chambersburg Pike. Pettigrew's commander, General Henry Heth, had warned him that the town might be defended by a "home guard," which he would have no trouble driving off. However, should he meet troops capable of resistance he was "not to bring on an engagement."
