All this while the Committee was airing another grievance. They clamored to have the twelve divisions of the army of the Potomac grouped into corps. They gave as their motive, military efficiency. And perhaps they thought they meant it. But there was a cat in the bag which they carefully tried to conceal. The generals of divisions formed two distinct groups, the elder ones who did not owe their elevation to McClellan and the younger ones who did. The elder generals, it happened, sympathized generally with the Committee in politics, or at least did not sympathize with McClellan. The younger generals reflected the politics of their patron. And McClellan was a Democrat, a hater of the Vindictives, unsympathetic with Abolition. Therefore, the mania of suspicion being in full flood, the Committee would believe no good of McClellan when he opposed advancing the elder generals to the rank of corps commanders. His explanation that he "wished to test them in the field," was poohpoohed. Could not any good Jacobin see through that! Of course, it was but an excuse to hold back the plums until he could drop them into the itching palms of those wicked Democrats, his "pets." Why should not the good men and true, elder and therefore better soldiers, whose righteousness was so well attested by their political leanings, why should not they have the places of power to which their rank entitled them? Hitherto, however, Lincoln had held out against the Committee's demand and bad refused to compel McClellan to reorganize his army against his will. He now observed that in the council which cast the die against the overland route, the division between the two groups of generals, what we may call the Lincoln generals and the McClellan generals, was sharply evident. The next day he issued a general order which organized the army of the Potomac into corps, and promoted to the rank of corps commanders, those elder generals whose point of view was similar to his own.(13) Thereafter, any reference of crucial matters to a council of general officers, would mean submitting it, not to a dozen commanders of divisions with McClellan men in the majority, but to four or five commanders of corps none of whom was definitely of the McClellan faction. Thus McClellan was virtually put under surveillance of an informal war council scrutinizing his course from the President's point of view. It was this reduced council of the subordinates, as will presently appear, that made the crucial decision of the campaign.
