there were four probable reasons for the deviation in the division's direction: first, regiments from the iii corps were unexpectedly in the devil's den area and they would threaten hood's right flank if they were not dealt with; second, fire from the 2nd u.s. sharpshooters at slyder's farm drew the attention of lead elements of law's brigade, moving in pursuit and drawing his brigade to the right; third, the terrain was rough and units naturally lost their parade-ground alignments; finally, hood's senior subordinate, gen. law, was unaware that he was now in command of the division, so he could not exercise control.
