In this frame of mind, he had a long confidential talk with Rosecrans on the subject. Rosecrans told him he ought to enter Congress. “I am glad for your sake,” said Rosecrans, “that you have a new distinction, and I certainly think you can accept it with honor; and, what is more, I deem it your duty to do so. The war is not over yet, nor will it be for some time to come. There will be, of necessity, many questions arising in Congress which will require not alone statesman-like treatment, but the advice of men having an acquaintance with military affairs. For this, and other reasons, I believe you will be able to do equally good service to your country in Congress as in the field.” Still General Garfield was undecided, except on one thing: that was to wait. Meantime the Chattanooga campaign came on, terminating at Chickamauga. Garfield was consumed with military zeal. He could hardly bear to think of chaining himself up to a desk for the monotonous sessions of Congress. All the military spirit which had blazed in his ancestors reasserted itself in him. His mind was absorbed with the stupendous problems of war which the Rebellion presented. Recognizing within himself an ability superior to many around and above him for grappling with questions of strategy, he was loath to abandon its exercise. It was evident, too, that in the presence of the commanding proportions of the military fame of successful Union generals, any merely Congressional reputation would be dwarfed and overshadowed. On the other hand, his brother officers urged him to go to Congress. There was a painful need of military men there. The enormous necessities of the army seemed too great to be comprehended by civilians. All men of soldierly instincts and abilities were at the front, and there was danger that the fountain of supplies in the Lower House of Congress would dry up. In the midst of these doubts, two weeks after the battle of Chickamauga, he was summoned to Washington. The War Department demanded a full explanation of the battle which had cost so many thousand lives. Garfield was known at Washington, and they determined to have from him the complete history of the campaign, and an explanation of the necessities of the situation.
