wright told lee that it was relatively easy to get to the crest, but it was difficult to stay there. a significant reason wright could not stay was his lack of support. two brigades were on wright's left and could have reinforced his success. carnot posey's brigade made slow progress and never crossed the emmitsburg road, despite protestations from wright. william mahone's brigade inexplicably never moved at all. gen. anderson sent a messenger with orders to mahone to advance, but mahone refused. part of the blame for the failure of wright's assault must lie with anderson, who took little active part in directing his division in battle.
