Found it in 3rd box. A book called "History of the Fourth Regiment of Minnesota Infantry Volunteers during the Great Rebellion: 1861-1865" by Alonzo Brown dated 1892

Spelling mistakes are mine. Hopefully it shows up right, as I typed in a document, then copied over to the board.

"The Captured Flags.
We quote from the St. Paul Press the following reference to the presentation by the Fourth Minnesota of their captured battle flags to the state :

Aaron Scribuer and John N. Bradford, two members of the Fourth Minnesota, arrived here yesterday, direct from Allatoona. They brought with them two battle flags which were captured from the Thirty-fifth and Thirty-ninth Mississippi regiments by the Fourth Minnesota during the battle of Allatoona, and deposited them with the adjutant general at the capitol. The following note accompanied them:

Headquarters Fourth Minnesota Infantry,
Allatoona, Ga., Oct. 11, 1864.
O. Malmroa, Adjutant Gtneral, State of Minnesota,
Colonel: By the bearer hereof, in behalf of the officers and men of my command, I have the honor to present to the state the colors of the Thiity-fifth and Thirty-ninth Mississippi Infantry, captured by this regiment in the action at this place October 5th.
I am, sir, very respectfully, your obedient servant,
James C. Edson,
Major, Commanding Regiment.

The flags are of coarse material and one of them is without any inscription whatever. The other is ornamented with the names of "Vicksburg," "Corinth," "Iuka," "Hatchie" and "Greenwood." It is a singular fact that in all those battles the Fourth Minnesota has met these two Mississippi
regiments The Fourth for its gallant action in this battle is entitled to a new set of colors, with the word "Allatoona" added to the other records of honor which already emblazon its banners. After the battle thirtyone whose time had expired were discharged and left for home.

Colonel Edson informed us that he sent the flags to St. Paul by John N. Bradford, and the latter informed us that he had to carry his knapsack and the flags about forty miles around breaks in the railroad and could not get anyone to help him carry them except Thompson Larraway.

Battle flag of the Thirty-ninth Mississippi Infantry (rebel) captured by the Fourth Regiment, Minnesota Veteran Volunteers, at the battle of Allatoona, Ga., Oct. 5, 1864.

The above notice is on a piece of common writing paper. It was written by Adjt. W. W. Rich and pasted to the flag, apparently before it was sent to Minnesota. There are no names of battles or any lettering whatever on it. The body of both flags is of red baize, the cross of blue baize (woolen). This has twelve stars and seems to be of full size and intact; the stars are of white cotton cloth sewed on the cross, three on each arm.
Battle flag of the Thirty-fifth Mississippi Infantry, captured by the Fourth Minnesota Infantry Veteran Volunteers, at the battle of Allatoona, Ga., Oct. 5, 1864.
I certify on honor that the rebel flag (without description) now in the office of the adjutant general of Minnesota should bear the above record of history.
W. W. Rich,
Late Captain Fourth Minnesota Veteran Volunteers.
116 Fifth Street S. E., Minneapolis.

This notice was written in recent years and is pinned to the flag of the Thirty-fifth Mississippi Regiment. This flag contains the names of Iuka, Corinth, Hatchie, Greenwood and Vicksburg. [The official records show that this regiment was in those battles. — Ed.] The letters and stars are made
of white cloth and sewed on each side of the flag. It has but eleven stars, the one on the lower corner having been cut off, and the entire end of the flag is ragged, as if a considerable part had been cut away.

Principal Musician W. S. Kimball cut a piece 6x6 out of a flag and has it now. Sergt. Wm. M. Davis of Company I also informs us that he has quite a large piece of a flag which he cut off and sent home, and says that he wrote in the letter that it was a piece of the Thirty-fifth Mississippi flag. Comrade James E. Conway of Company G has now in his possession a piece of silk and one star, which he says he cut from a flag, and claims be captured it. It is also claimed that John Hughes of Company F captured a silk flag. But poor health and the shortness of life prevents our settling these questions.
The statement about Hughes is supported by pretty good evidence. As all of the flags were captured by the entire garrison at the post, we fail to see how any person who picked one up and carried it in deserves any special credit. Young might just as rightfully claim that he captured all of the prisoners. We believe, from the evidence received, that three flags were captured by our men at this place, one of which was made of silk and torn up and divided among the boys.
