On July 2:
XII Corps is on Culp Hill
I & XI on Cemetery Hill or nearby
II Corps on Cemetery Ridge
VI Corps not yet arrived (some just arriving?)
III southern cemetery ridge to LRT then moved westward
Where was V Corps? Arriving? Reserve?
Wasn't Sedgwick's VI Corps almost 1/5 of the entire AOTP? Without them Meade didn't have many men to spare, especially with I & XI chewed up on July 1.
IF Meade was slow to realize Sickles predicament it may have something to do not only with miscommunication, but with Meade not imaging Sickles would have done something so dangerous and insubordinate until he saw it for himself.
