"COL. BACHELDER:--I have examined your beautiful drawing of the Battle-field of Gettysburg and vicinity. The certificates of Gen. Meade and the Corps Commanders, which appear on its face, establish its accuracy on the highest authority. Your personal explorations, and your inquiries of all the commissioned officers in command of the Union Army, and of the Confederate officers made prisoners, have furnished you means of information not possessed, I imagine, by any other person. Such opportunities of observation as I had during three days passed at Gettysburg satisfy me of the fidelity of your delineation of the position of every regiment of the two armies on each of the three eventful days. * * * * I may add, that the engraving is beautifully executed and colored. Wishing you ample remuneration, "I remain sincerely yours, "EDWARD EVERETT." * * * * * "HEAD-QUARTERS FIFTH ARMY CORPS. _Sept. 28, 1864._ "MR. JNO. B. BACHELDER:-- "DEAR SIR:--I am exceedingly gratified with receiving a finished copy of your print of the Battle-field of Gettysburg. I am familiar with your long and untiring labors in all the fields where truth could be reached, and know that your efforts were crowned with a success that leaves nothing more to be desired. You are authorized to add my name to those who bear testimony to Its accuracy. "Very respectfully your obedient servant, "G. K. WARREN. "_Maj.-Gen. Vols., Comd'g 5th Corps._ "_Ch. Eng. at Gettysburg._" * * * * * "ORANGE, _Oct. 1, 1864_. "JNO. B. BACHELDER, Esq.:-- "MY DEAR SIR:--I have carefully examined your Isometrical Drawing of the Battle-field of Gettysburg, with great interest and much profit. Never having been on that field, of course I can not express an opinion as to its accuracy--so abundantly indorsed for, however, by most competent judges: but I can say that it has given me a much clearer idea of the battle than I had before, and I earnestly hope that you will find it convenient to illustrate others of our great battles in the same manner. "I am very truly yours, "GEO. B. McCLELLAN." * * * * * "HEAD-QUARTERS DEP'T AND ARMY OF THE TENNESSEE. _Oct. 24, 1864._ "MR. JNO. B. BACHELDER:-- "MY DEAR SIR:--I was much gratified on receiving a copy of your beautiful drawing of the 'Gettysburg Battle-field.' I have never seen a painting or topographical map that could give so vivid a representation of a great battle. I regard it as an honor that you have associated my name with those of other corps commanders in your historical picture. Be pleased to accept my kind regards. "Respectfully yours, "O. O. HOWARD, _Major-General_." * * * * * "COL. JNO. B. BACHELDER:--
