I agree with the premise of the title for this thread, the Artillery fire was impressive, but was not nearly as effective as it really needed to be. But, I believe that Lee gets too much of a pass on responsibility for that fact. As noted by others on this thread, Lee was well aware of the deficiencys in his Aartillery both in command and ammunition. But, apparently by Day 3, Lee was committed to throwing the results of the attack upon the shoulders of the men in the ranks of the ANV, whom he, more or less, confessed, that he believed, when properly planned ans executed, a full blooded assault could not be stopped.
