Thus far the Army of the Ohio is given no credit for participation in the Sunday battle. Buell and Nelson's division of that army were at Savannah on the evening of the 5th, but Buell refrained from attempting to report his presence to Grant until the next morning. Grant had then departed for the battle-field. Grant was eating his breakfast at Savannah when the battle opened, and at first determined to find Buell before going to his army; but the sound of guns was so continuous, he felt that he should not delay a moment, and hence left a note for Buell asking him to hasten with his reinforcements to Pittsburg Landing, gave an order for Nelson to march at once, and then proceeded by boat up the river. Buell, after reiterating Grant's instructions to Nelson to march to opposite the Landing, himself about noon proceeded by boat to that place with his chief of staff, Colonel James B. Fry.( 9) Buell seems to have been much impressed by the number and temper of the stragglers he saw on his arrival, and he made some inquiry as to Grant's preparations for the retreat of his army. Grant, learning that Buell was on board a steamboat at the Landing, sought him there, hastily explained the situation and the necessity for reinforcements, and again departed for the battle-field. He had before that been in the thick of the fight, where his sword and scabbard had been shot away. Not until 1 or 1.30 P.M.( 9) did the head of Nelson's column move, Ammen's brigade leading, for Pittsburg Landing, and then by a swampy river road over which artillery could not be hauled. The artillery went later by boat. At 5 or 6 P.M. the advance,--eight companies of the 36th Indiana (Col. W. Grose)--reached a point on the river opposite the Landing. These companies were speedily taken across the Tennessee in steamboats and marched immediately, less than a quarter of a mile to the left of the already massed artillery, to the support of Grant's army, then engaged in its struggle to repel the last assault of the Confederates for the day. Other regiments (6th Ohio, Colonel N. L. Anderson, 24th Ohio, Colonel F. C. Jones) of Ammen's brigade followed closely, but only the 36th Indiana participated in the engagement then about spent. This regiment lost one man killed.(10) The expected arrival of the Army of the Ohio and the presence of such of it as arrived may have had a good moral effect, but its late coming gives to it little room to claim any credit for the result of the first day's battle.
