For what it is worth, the meeting called by Meade after the first day, was a meeting with only those senior officers who had arrived on the field that day. When asked if they should remain all agreed that they should. Meade's reply was something like: "Good, because it is too late to change now." The so called "Council of War" at Gettysburg took place on the night of day 2. It was Butterfield (not a supporter of Meade) who called it a "Council of War" and who suggested that they 12 assembled generals took a vote. For the record, Meade had already sent a message to Halleck indicating the intention to hold the position and see what developed. My view is that the meeting on July 2 was to ensure that the whole senior command bought into staying put, which they did.
