In the company of Colonels Black and Freemantle it seems, General Longstreet scouted the area. According to Freemantle, this occurred at 7 a.m. and although Black did not mention a time, through the context of his account it was before 8 a.m. Black wrote,
By this time my command of cavalry had come up and I accompanied Gen'l Longstreet to the right & top of a hill on a pike leading out of Gettysburg [The Fairfield Rd.]. Here he made his headquarters & ordered me to take possession of a bridge in sight [the stone bridge crossing Marsh Creek near the Black Horse Tavern] & supply him with two trusty cavalry subalterns. I did….
I went to the foot of the hill and bridge to see about something & ordered Lt. Marshall to examine a large house near the bridge, a kind of tavern & I think called the "Black Horse Tavern". Marshall did so and found a number of whiskey barrels. These I promptly ordered stored and soon after informed Gen'l L. what I have done.
"I suppose," said he, "You saved some for yourself & me."
"Excuse me, General, as I do not drink, I forgot to do so."
I applied for orders and was ordered to stay at his headquarters & await orders. I did so and so was a spectator at a safe distance of the fight that took place that day.
Besides Black's antidote, he was very specific about the location of Longstreet's headquarters in which, until recently was not thought to have existed at Gettysburg. The hill on the pike he is talking about is undoubtedly Bream's Hill on the Fairfield Rd. It is overlooking the Black Horse Tavern in which was mentioned by name in the account. Incidentally, an oral tradition has been passed down through the years that a wooden structure, originally a schoolhouse, was the site of Longstreet's headquarters at Gettysburg. This was investigated by the Park's historian and found that it did not have merit. The structure was moved from its original location and used as a tourist attraction at the time, and it was thought to be the original Pitzler's Schoolhouse near the line of battle on the 2nd of July. It was proven not to be and rightfully so, and for these reasons the claim was dismissed. However, the historian did not have Colonel Black's account or any other account for that matter, that Longstreet even had a headquarters at Gettysburg, and so the structure was taken apart but preserved. Luckily the building could not be taken off the historic structure list and the Park Service had placed it in storage. The reason I mention this is that because of Colonel Black's account we have a location and confirmation that General Longstreet had established a headquarters at Gettysburg, and at that very spot pointed out by Black, there was an old schoolhouse in 1863, not Pitzler's but Adam Butts' Schoolhouse.
