THE OFFICIAL, OR THOM, MAF OF THE BATTLE OF SHILOH.

On Nov. 28th, 1884, two weeks before the Official Mapwas sent to press with General Grant’s Shiloh article (in“The Century” magazine for February, 1885), inquirywas made of General George Thom concerning its his-tory. He replied, Dec. 5th, that it was prepared underhis direction as Chief of Topographical Engineers onHalleck’s staff soon after the battle, while the Uniontroops were still encamped on and near the battle-ground, and that Generals Grant, Buell, and Shermanfurnished him with information as to the positions occu-pied by the troops in the battle. On Dec. 15th, GeneralThom “called the attention of General Grant to certaincriticisms which General Sherman published on theOfficial Map ... of that battle-field, at a meeting ofthe Army of the Tennessee held in Cincinnati on the 6tliand 7th of April, 1881.” In reply, General Grant wrote:

“ 3 E. 66th St., N. Y. City, Dec. 30th, 1884.

“ MY Dear General Thom : Your letter of the 15th instantwas duly received, and I now have yours of the 28th. In

regard to the matter of the map which ‘The Century’ mag-azine is to use in illustration of the article which I have fur-nished on the battle of Sliiloh, I have examined it, and seenothing to criticise. I was not aware before the receipt ofyour first letter that General Sherman had ever criticisedyour map of the battle-field of Shiloh. I have not spoken toSherman on that particular subject recently, nor ever that Iremember of. * The Century,’ as I understand, has takenthe Official Map to illustrate my article. Very truly yours,U. S. Grant.”

General Grant's approval of the use of the OfficialMap with his article was given in an interview with oneof the editors over the map, at his house early in Nov.,1884. On June 24th, 1885, five months after the appear-ance of the article, Colonel F. D. Grant wrote to theeditor from Mount McGregor, inclosing notes for therevision of the map, and saying: “He [General Grantlwould like you to make the changes in the map, indi-cated.” For General Grant’s map and Colonel Grant’sexplanation, see page 470.— Editors.
