At six o'clock, Colonel Moore, of the Twenty-first Missouri, also of Peabody's brigade, was directed by General Prentiss to move out with five companies to support the pickets. About half a mile from camp he met the three companies of the Twenty-fifth returning. Despatching the wounded on to camp, and sending for the rest of his regiment, he halted with the detachment of the Twenty-fifth till joined by his remaining five companies. So reinforced, he continued his advance three hundred yards, met the advance of Shaver's brigade, halted on the edge of a field, and repulsed it. Colonel Moore being wounded, Lieutenant-Colonel Van Horn took command, and was further reinforced; after an engagement of half an hour, was overpowered and fell back to the support of the brigade. According to General Bragg's report, Johnston's line of battle, after marching less than a mile beyond the scene of the first attack made by the three companies of the Twenty-fifth Missouri, came upon the strengthened National pickets, which he calls advanced posts. These fell back fighting. The army advanced steadily another mile, pushing back the fighting pickets, and then encountered the National troops "in strong force almost along the entire line. His batteries were posted on eminences, with strong infantry supports. Finding the first line was now unequal to the work before it, being weakened by extension, and necessarily broken by the nature of the ground, I ordered my whole force to move up steadily and promptly to its support." Thus opened the battle of Shiloh. A combat made up of numberless separate encounters of detached portions of broken lines, continually shifting position and changing direction in the forest and across ravines, filling an entire day, is almost incapable of a connected narrative. As the first shock of the meeting lines of battle was near the right of the National line, an intelligible account may be given by describing the action of the divisions of Grant's army separately, beginning with the right, or Sherman's.
