It must have been quite clear to General Lee,on that May 7th.evening when the federal army came back so quickly for more, that this fellow Grant was different from all the others.He would have known then that unless he could seriously damage or destroy those people in the field then the results were foregone. Unfortunately attrition of troops and experienced officers prevented an opportunity.Grant made many mistakes but Lee was just unable to take advantage.And of course both armies at this stage of the war regularly entrenched almost immediatly when placed in a position.
