As to operations in the upper valley of the Holston, it was determined to occupy Bull's Gap at an early day, and to keep up such an apparent purpose of advancing as should detain Longstreet in East Tennessee as long as possible. If he retreated he was to be followed, so as to induce him to burn the railway bridges, and thus to avoid disclosing our own purpose of leaving that portion of the valley which we should plainly proclaim if we ourselves should destroy the railway. Everything was to be ready for movement, and at the last moment, if the enemy had not already done it, we were to burn railway bridges and tear up the track for a considerable distance. Then the divisions which were to take the field in Georgia were to march rapidly to Cleveland, and come in on the left of Sherman's grand army as he advanced from Chattanooga. As the plan of campaign thus took definite shape, it gave the occasion also for a settlement of my personal problem of permanent assignment to duty. It had become evident that there was no room for transfer to another command, and the active part marked out for the Twenty-third Corps removed the only ground for wishing it. No better soldiers could be found than those which made up our divisions, and my acquaintance with General Schofield had ripened into a confidence which made me entirely content to follow him as my commander. He warmly invited me to continue permanently in the position of chief of staff, but gave me the alternate choice of one of the divisions of the active column. My preference for responsible command in the field decided me to take a division, and by his further permission I chose the third, in which were a considerable number of officers who had served with me in other campaigns. [Footnote: Official Records, vol. xxxii. pt. iii. p. 245.] I would not be understood, however, to depreciate the position of chief of staff of such a department and army. Properly filled, few positions in active service could be pleasanter or more useful. I had tested this during the six weeks preceding, and had found the associations and the duty every way most agreeable. The general was always prompt to assume his proper responsibility and to order the movements or the administrative acts which are peculiarly the province of the commander; but he gave me the task of arranging the subordinate details, and the authority to direct them in his name. To distribute the parts each corps or division was to perform; to co-ordinate all the arrangements so that they should move harmoniously; to bring to a common centre all the information, external and internal, which affected the conduct and efficiency of the whole; to supervise the matters of organization, of equipment, and of supply; to consult with the medical director as to hospital work and the sanitary condition of the army, and to be guarantor that the common end is vigorously and intelligently pursued by every part of the army,--all this, as scarcely needs
