General Nelson, a few days before his death, in conversation with Larz Anderson and two or three other gentlemen, said: “During eight hours, the fate of the army on the field of Shiloh depended on the life of one man: if General Sherman had fallen, the army would have been captured or destroyed.”

General Halleck, in his despatch to the Secretary of War, recommending General Sherman for promotion, said of him: “It is the unanimous opinion here that Brigadier-General W. T. Sherman saved the fortunes of the day on the 6th of April, and contributed largely to the glorious victory of the 7th. He was in the thickest of the fight on both days, having three horses killed under him, and being wounded twice. I respectfully request that he be made a major-general of volunteers, to date from the 6th instant.”

Acting upon this recommendation, General Sherman was promoted to the rank designated, to date from May 1st, 1862.

I shall give you now a letter of considerable length, written by General Sherman himself about the battle. Some of my readers may not care to read it all; but it should have a place in the annals of his life, because it is one of many illustrations of his power with the pen, and is also his honest and truthful record of the great contest at Pittsburg Landing:

“Professor Henry Coppee, Philadelphia:

“Dear Sir: In the June number of the United States Service Magazine I find a brief sketch of Lieutenant-General U. S. Grant, in which I see you are likely to perpetuate an error, which General Grant may not deem of sufficient importance to correct. To General Buell’s noble, able, and gallant conduct you attribute the fact that the disaster of April 6th, at Pittsburg Landing, was retrieved, and made the victory of the following day. As General Taylor is said in his later days to have doubted whether he was at the battle of Buena Vista at all, on account of the many things having transpired there, according to the historians, which he did not see, so I begin to doubt whether I was at the battle of Pittsburg Landing of modern description. But I was at the battles of April 6th and 7th, 1862. General Grant visited my division in person about ten a. m., when the battle raged fiercest. I was then on the right.

“After some general conversation, he remarked that I was doing right in stubbornly opposing the progress of the enemy; and, in answer to my inquiry as to cartridges, told me he had anticipated their want, and given orders accordingly; he then said his presence was more needed over at the left. About two p. m. on the 6th, the enemy materially slackened his attack on me, and about four p. m. I deliberately made a new line behind McArthur’s drill field, placing batteries on chosen ground, repelled easily a cavalry attack, and watched the cautious approach of the enemy’s infantry, that never dislodged me there. I selected that line in advance of a bridge across Snake Creek, by which we had all day been expecting the approach of Lew. Wallace’s division from Crump’s Landing. About five p. m., before the sun set, General Grant came again to me, and, after hearing my report of matters, explained to me the situation of affairs on the left, which were not as favorable. Still the enemy had failed to reach the landing of the boat.

“We agreed that the enemy had expended the furore of his attack, and we estimated our loss, and approximated our then strength, including Lew. Wallace’s fresh division, expected each minute. He then ordered me to get all things ready, and at daylight the next day to assume the offensive. That was before General Buell had arrived, but he was known to be near at hand. General Buell’s troops took no essential part in the first day’s fight, and Grant’s army, though collected together hastily, green as militia, some regiments arriving without cartridges even, and nearly all hearing the dread sound of battle for the first time, had successfully withstood and repelled the first day’s terrific onset of a superior enemy, well commanded and well handled. I know I had orders from General Grant to assume the offensive before I knew General Buell was on the west side of the Tennessee. I think General Buell, Colonel Fry, and others of General Buell’s staff, rode up to where I was about sunset, about the time General Grant was leaving me. General Buell asked me many questions, and got of me a small map, which I had made for my own use, and told me that by daylight he could have eighteen thousand fresh men, which I knew would settle the matter.

“I understood Grant’s forces were to advance on the right of the Corinth road and Buell’s on the left, and accordingly at daylight I advanced my division by the flank, the resistance being trivial, up to the very spot where the day before the battle had been most severe, and then waited till near noon for Buell’s troops to get up abreast, when the entire line advanced and recovered all the ground we had ever held. I know that with the exception of one or two struggles, the fighting of April 7th was easy as compared with that of April 6th.
