In April and May, 1877, three companies (C, F and G) were moved from
Cheyenne Agency, and three companies ( A, B and H) from
Fort Yates in the
Standing Rock Agency to the
Little Big Horn, Montana, under the command of Lieut.-Colonel
G. P. Buell,
11th Infantry, where they constructed the post of Fort Custer. On June 9, 1877, Lieut. Col. Geo. P. Buell and 2 companies Eleventh Infantry (C and F), together with a number of mechanics, arrived, per steamer Florence Meyer, en route to build Post No. 2 on the Bighorn River. The construction of Fort Custer, on the Big Horn, was entrusted to Lieutenant-Colonel G. P. Buell, of the Eleventh Infantry. Colonel Buell, with four companies of his regiment and a large force of mechanics and laborers, left Bismarck by steamers for the site of the post on the 16th of May. Owing to the wretched character of his boats, and to an accident which happened to one of them, he did not reach his destination until the 23d of June. Subsequently two additional companies of his regiment were sent to him. It had been determined to build this post from material to be found in the country; and as soon as Colonel Buell had put up temporary storehouses to protect his supplies, he commenced cutting logs, baking brick, and sawing lumber. The lumber in this immediate vicinity is cotton wood, and, with the exception of some finishing lumber—pine—sent up from Bismarck, the post was built of this material. The post is intended for the same number and description of troops as Fort Keogh. The buildings are not framed, but they are built up of planks two inches thick by six inches wide, laid flat one upon another, forming a solid wall six inches in thickness. The officers' quarters are of one story and an attic. All other buildings are of one story. The site of the post is on an extensive elevated plateau in the fork of two streams. Colonel Buell was originally instructed to place it on the left bank of the Bighorn, as near to the mouth of the Little Bighorn as the nature of the ground would permit. Immediately after his arrival he made a thorough examination of the whole neighborhood, and became so well satisfied of the superior advantages of the plateau in the fork over any other possible situation, that he selected it as the site. His action in this respect was subsequently fully approved. Many unforeseen obstacles delayed the completion of the post; but its construction is so far advanced, that the garrison, its animals and supplies, will be well sheltered during the winter. Lieutenant-Colonel Buell deserves great credit for the activity, energy, and resource which he has displayed. Fort Custer had quarters for 10 companies including stables for 6 troops of cavalry. It was built with buildings surrounding a large parade ground but had no walls or other fortifications ==Naming==
