In the Journal of the House of Representatives of the United States for 1825-1826, and more specifically, on March 23, 1826, a Kentucky representative, Mr. James Johnson, submitted a resolution that the military build an armory at Horse Shoe Bend, in Pendleton county, Kentucky. That's it on the little images at the left, starting in the middle of the first page.

The petition is signed by a number of Pendleton Countians, and you can read the entire petition. 

His resolution read:

Resolved, That the Committee on Military Affairs be instructed to report a bill authorizing the Secretary of War to appoint three Commissioners to survey and examine the Horse Shoe Bend upon Licking river, in the county of Pendleton, in the State of Kentucky, and if, upon such survey and examination, the same shall be found suitable to authorize the President of the United States to cause to be erected, at the Horse Shoe Bend aforesaid, a National Armory, similar to those already erected at Springfield and Harper's Ferry.

The said resolution was read, and considered until the arrival of the hour for passing to the orders of the day.

Skip forward to December 18, 1826 – seven months later.  In the Journal of the Senate of the United States of America, 1789-1873, we read that:

Mr. Johnson, of Kentucky, presented the petition of sundry inhabitants of Pendleton county, in the State of Kentucky, praying that a National Armory may be established at a Point on Licking river called the Horse Shoe Bend; and

Ordered, That it be referred to the Committee on Military Affairs.

That was in the Senate, in the House, on the same day, we have, from the Journal of the House of Representatives of the United States, 1826-1827, December 18, 1826, this item:

Mr. McHatton laid the following resolution on the table for cconsideration to-morrow, viz: Resolved, That the Secretary of War be instructed to appoint three commissioners to survey and examine the Horse-Shoe Bend, upon Licking River, in the County of Pendleton, in the State of Kentucky; and if, upon such survey and examination, the same shall be found suitable, to authorize the President of the United States to cause to be erected at the Horse-Shoe Bend, aforesaid, a national armory, similar to those already erected at Springfield and Harper's Ferry; that they report the same to the Secretary of War, who shall, early in the next session of Congress, report the same to this House.

One week later, we can read in the Journal of the House of Representatives of the United States, 1826-1827, December 26, 1826.

The House proceeded to the consideration of the resolution moved by Mr. McHatton, on the 18th instant; when the same was read, and modified, as follows:

Resolved, That the Committee on Military Affairs be instructed to inquire into the expediency of authorizing the Secretary of War to appoint one or more skilful engineers to examine the Horse Shoe Bend, on Licking river, in Pendleton county, in the State of Kentucky; and, also, the waters of the Tennessee and Cumberland rivers, as far as the falls of the latter: and to report upon the fitness of these places, respectively, as a site for a National Armory, similar to the armories of the United States, at Springfield and Harper's Ferry.

A motion was then made by Mr. Marable, to amend the resolution by inserting therein, after the word "latter," these words: "Also, the site on the Narrows of Harpeth, (as suggested by the Legislature of the State of Tennessee.) on the Cumberland River."

Pending the question on this amendment--it was again

Ordered, That the said resolution do lie on the table.

The Horse Shoe Bend Arsenal is heard of no further.
