Here is the “Lee’s Headquarters” that wasn’t:

The 83rd Pennsylvania Flank Markers – top RFM, bottom LFM:
The View of Col. William Oates, Commanding 15th Alabama as he exited the tree line and saw 20th Maine [Chamberlain] lined up “flank to flank” according to his after action report. See note below for what else this image tells us:
Note: Chamberlain’s men are arrayed on Vincent’s Spur [straight ahead at top of image] facing Oates’ 15th Alabama. Later in the action, Chamberlain refuses his line creating a very tight “V”, the bottom of which is at the right of the Spur as seen here. When Chamberlain orders the bayonet charge, the far side of the “V” swings to the right to form a straight line with the left side of the “V” which has not yet moved. When the Regiment is in a straight [reasonably] line, they push off the Spur and advance on the position where this camera was located. Thus we have additional proof of where Oates Regiment [15th Alabama] advanced to this fight: over the ridge on the west side of Big Round Top, not over the peak of Big Round Top.
