They ought to have known better, of course; but they did not, and they would not let Stuart teach them better, though he, with his preternatural activity, had followed the panic-stricken fugitives far enough to know what their moral condition was. Let us frankly recognize facts and take account of them in the reckoning of history. Johnston and Beauregard were accomplished officers, familiar with every detail of technical military duty. But neither of them was as yet experienced in the command of armies or the conduct of campaigns. Until a few months before that battle was fought they had been mere captains of engineers. Neither had ever commanded any force greater than a company. Neither had ever seen an army of proportions half so large as those of the force that fought at Manassas. Neither had ever had even the smallest experience in grand strategy. They were mere apprentices still in the art of war. They had not yet fully learned their trade. They utterly failed to understand what their victory meant. They had no conception of the disorganizing, disintegrating effects of that victory upon their adversaries. They were utterly incapable of understanding their opportunity or of taking advantage of it. Because of their inexperience they let slip the finest opportunity that was at any time afforded to commanders on either side to achieve a quick and decisive result. With no purpose or willingness to undervalue the ability or the devotion of two officers who afterwards achieved well-deserved distinction as the commanders of armies, it may fairly be pointed out that they were in command at Manassas not because of known and demonstrated fitness for command, but solely because of their technical rank in the old, peace-time army of the United States, where promotion was exclusively by seniority--perhaps the unsafest ground of promotion that was ever devised by the evil ingenuity of officialism and professional self-regard. Whatever capacity these two officers afterwards developed, it is very manifest that at the time of the Manassas battle they both showed themselves incapable of seizing upon the opportunity that victory offered them in any such masterful way as that in which Lee afterwards seized upon far less obvious opportunities at the end of the Seven Days' Battles and again after Chancellorsville.
