Fort Union
By David Sedivy



The Santa Fe Trail was responsible for a growing new nation. The trail began as a Native American route as well for Spanish exploration across the plains of America. It became a link between two countries- the United States and Mexico. The trail evolved into a vital trade route for settlers and the military. Passage over the trail was full of danger and misery.

The development of Fort Union was linked to a long series of events, and its history is inseparable from that of the Santa Fe Trail. Mexico declared its independence from Spain in 1821.This established free trade. The following year large caravans began crossing the plains from Missouri to Taos and Santa Fe.

The federal government recognized the importance of the Santa Fe Trail, and by 1825 the United States Congress passed a bill to survey the trail. This was the first road surveyed west of the Mississippi River. The trade route was essential for the development of both countries. Western expansion of the United States was on. Tourists began to appear on the trail along with the traders and settlers. By 1831 normal trade goods were common in Santa Fe. To maintain profit levels, traders usually had more than one wagon.When Mexico levied taxes on the number of wagons, the size of wagons increased.1 During this time improvements in transportation took place, including the development of stagecoach and mail lines. As trade increased along the trail the wagon trains became targets for the Indians, protection of the caravans became necessary. In 1833, President Andrew Jackson organized the dragoons as the first full-time cavalry branch of the United States.2 Jackson realized that foot soldiers were of little help in the frontier. In 1834, the dragoons escorted a wagon train along the Santa Fe Trail. This was just the start of increasing United States military involvement along the trail.

The Mexican government tended to view the trail going to Santa Fe as a military highway leading straight to its northern border. These fears became a reality in 1846, when General Kearny peaceably conquered New Mexico and made it United States territory. The United States military established a handful of garrisons throughout the new territory. The cost of supplying the army in New Mexico was of great concern in Washington D.C. On April 1, 1851, Secretary of War Charles Conrad wrote to Colonel Edwin Sumner of the First Dragoons. First, Conrad announced in his letter that Sumner was to take command of the Ninth Military Department (New Mexico). Conrad stated that he wanted to see changes of more efficient protection of the country with a "diminution of expense." Conrad told Sumner to make changes wherever he deemed necessary. The order went on to say that Sumner could choose new locations for garrisons based on:

1st. The protection of New Mexico.
2nd. The defense of the Mexican Territory, which we are bound to protect against the Indians within our borders.
3rd. Economy and facility in supporting the troops, particularly in regard to forage, fuel, and adaptation of surrounding country to cultivation.3

These orders were the foundation for Fort Union, New Mexico. The first two items were based on traditional military strategy: presence, defence, and when necessary, offence. The third item is key to understanding how and why the buildings of Fort Union were constructed.

Sumner arrived in Santa Fe on July 19, 1851. His first act as commanding officer was to "break up the post at Santa Fe, that sink of vice and extravagance, and to remove the troops and public property to this place (Fort Union). I left one company of Artillery there... These evils are so great that I do not expect to eradicate them entirely until I can bring the troops together in considerable bodies..."4 Sumner believed that removing all the troops from town would improve discipline and moral. Sumner resented the townspeople of Santa Fe living in one way or another at government expense. He was determined to cut back the waste in government spending.

The Ninth Military Department under command of Sumner first arrived at what would later be called Fort Union on July 26, 1851.5 Sumner began construction at a strategic location five miles from the Rio Mora on El Arroyo del Coyote near the Turkey Mountains. The sight was six miles north east of the confluence of the Cimarron and Mountain routes of the Santa Fe Trail, twenty-six miles from Las Vegas, and eighteen miles from Mora.6 One army summary stated that "the location was on the line of the great traveled route to Santa Fe, with a view to the protection of passing wagon trains and the isolated settlements from the Apaches who roamed over the wide district of country to the east and south".7

When the army moved into the area of Fort Union in 1851, the first order of business was the construction of temporary shelters while the construction of the more permanent shelters could be made. A report prepared in August, 1851 summarized the resources of the area. Corn and hay were available for purchase, and the grazing around the post was very good during the summer and fall. The report noted:

There is sufficient building materials near the post for all purposes, consisting of a very fine white sand stone, clay for bricks and adobes and pitch and spruce pine in the mountains from 9 to 30 miles of the post. All other articles required for building would have to come from the east, as they are not produced by this department... The greatest objection to this point as a military post is the want of running water for stock... The usual and only transportation used here are wagons, carts, and pack mules.8

Despite various Army regulations that governed building construction in the late 1800’s frontier army construction was rag-tag at best. As one historian pointed out, the only thing uniform about the army in the ninetieth century was its uniform.9 With fall and winter approaching construction of quarters was the first priority. The new occupants lived in army tents while buildings were under construction. The rough, unpeeled log buildings went up slowly.

By December, 1851, the quarters were still short of completion, but the availability of boards for roofs and floors had improved. A progress report from Major Sibley noted:

The quarters for one company and the hospital are competed except the glazing of the windows, and the hanging of the doors. I am now busily occupied in sawing the lumber necessary to cover the other soldiers quarters. -The officers quarters are all covered and, with a few exceptions, floors are laid in one room of each set and the quarters are occupied by officers and their families.10

By April, 1852, Sibley reported to his superiors that with the exception of a few shops and a storehouse, all of the buildings had been erected and were in a relatively habitable condition. By September,1852, the first Fort
Union was operating efficiently.11

Captain Isaac Bowen and his wife Katherine were among the early arrivals to Fort Union. Katie and Isaac wrote home frequently to her family. In one of Katie Bowen’s letters she noted that the winds at Fort Union were very strong. According to her, they blew hard for a week from the north, then quieted down, and then they blew hard from the south. She had trouble keeping the dirt out of her new house, and she wrote home that the dirt drifted in like snow in every unprotected crevice. Occasionally she even had to shovel out her house because it was so deep. She wrote to her parents: "How I would like that you could look in and see how primitive we are in our log houses, white-washed logs overhead, chinked and covered with earth to shed snow and rain."12

Fort Union was located on the Mora land grant. The United States government was supposed to pay rent for the use of the land.13 Although the secretary of the interior tried to amend the Mora land grant so that the improvements would belong to the United States, it turned out that such an amendment was not legal. The grantees, however could not compel the government to abandon the post. So, the government concluded that it owned the buildings and improvements, and could not be forced to leave the post. Thus, the federal government had no land ownership at Fort Union.14

The barter system was a big part of daily life at Fort Union. Families traded for vegetables, butter, eggs and herbs. Their reliance on supplementing army rations had an impact on the physical appearance of the post. The troops became creative in providing for extra food. They had small gardens and raised stock. In September, 1859, the post commander issued an order stating that from that time forward, hogs were prohibited from running loose through the garrison. The hogs ate anything they found and the troops in turn ate them.15

An 1853 inspection of the fort by Joseph Mansfield noted some points about Fort Union. He criticized the location of the fort, saying that it was to close to the mesa for adequate defense. Mansfield found the post "in a high rate of discipline and every department of it in good order," especially when the troops had to do everything from building quarters, gathering timber and hay, farming, escorting trains, and pursuing Indians.16

The buildings at the first fort were deteriorating at a rapid rate. They were not constructed as permanent buildings. In late 1856 Assistant Surgeon Jonathan Letterman did an inspection report at Fort Union. He wrote, when the rains came, the run-off drained down the mesa sometimes which such force that the buildings were flooded. As far as the quarters were concerned, he descibed them as made of unseasoned, unhewn, and unbarked pine logs, placed upright in some and horizontal in other houses. The logs were decaying fast. The unbarked logs afford excellent hiding places for that annoying and disgusting insect, the cimex lectularius (bedbug). By 1856, one barracks had been torn down, and others were in imminent danger of collapse.17

The multiple functions at Fort Union-army post, supply depot, and arsenal-led to some animosity between various units. The quartermaster, the fort, and the arsenal all employed civilian employees. The depot quartermaster often outranked the post commander. The military storekeeper who ran the arsenal reported directly to the chief of ordnance in Washington instead of to the post commander. Although the fort was known as one large unit, it was really three units whose leaders reported to three separate superiors.18

In the fall 1861, Captain Grover ordered the construction of a new fort. Shortly after, women and children were removed and sent to Las Vegas This fort would be located just east of the original post. The army anticipated an attack from Texas troops, who at the time were moving to seize and hold New Mexico for the confederacy. Fort Union was the main supply depot for the territory. Control of the fort ment command of all its arms and materiel as well as command of the Santa Fe Trail and communication with the states.

The first fort was in an indefensible position because of the higher ground in the rear and both flanks. The idea was to move the post out of range of field pieces and small arms. Earth fortifications and entrenchments had well known advantages. The main advantage was defense. It was said that good troops inside an earthwork could withstand an attack of three to four times as many equally good troops.19

By January of 1862, nearly all of the quartermasters property, ordnance stores, and provisions had been moved into the star fort. An article in Denver’s Rocky Mountain News in February,1862, described the star shaped fort as:

One of the strongest forts in the Western frontier. Its size is seven hundred and fifty feet square, parapets (an earth embankment to intercept enemy fire) seven feet high. From the level of the ground on the inside with a ditch on the outside eight feet deep and fifteen feet wide. Quarters for two companies built on the insides with a large magazine, and quarters are built outside the fort in an acute angular form from the sides of the fort, one each of the four sides with officers quarters intervening. The ordnance will be put in position early in May. Also other necessary buildings will be erected as soon as weather permits. The force at this fort is six companies numbering about three hundred men.20

Even during the late 1800’s the news media gave away military secrets. However, the confederate troops, had been spying on the fort since August, 1861.

In March of 1862, the threat of the confederate troops became a reality. Confederate troops in search of supplies and control of the southwest threatened to invade Fort Union. Union forces stopped the confederate army at the battle of Glorieta Pass. The battle of Glorieta pass was the turning point of the Civil War in the far west. Fort Union was in little danger for the rest of the Civil War. The importance of Fort Union during that time period still remained high not only because it was the main supply and munitions depot in the southwest but also because of the need to keep the Santa Fe Trail open despite Apache and Navajo uprisings.

The strategic vulnerability of the star fort was disclosed in June 1862, when the post commander gave a test consisting of a six-pound and a twelve-pound howitzer pointed at the fort. The six-pounder was placed at the foot of the hills, and the twelve-pounder was placed at the crest of the hills above the first fort. Both guns were loaded with normal charges and shot off. Both guns had the fort in range. Then in a separate test, a six-pounder was set off from the inside the star fort, its range only carried half way to the hills.21

The conditions in the first fort and also the star fort (both of which were still being occupied) were so bad that construction began in 1863 on the third fort.

The star fort being built mostly underground had poor ventilation, lighting and was constantly damp. In addition the pools of water next to first fort were disappearing and the local springs were drying up. On October 16, 1866, a huge rainstorm flooded the star fort with eight to twelve inches of water. A report written by the post surgeon the following day said all the men were damp. The dampness coupled with the intermittent storms convinced the surgeon that the incidence of disease including, fever, rheumatism, and heart complications were "due in great part to the casemated barracks occupied by the troops at this post". He told the post commander that the only way to fix this situation was to repair the old barracks, move into tents, or move early into the new quarters at third fort.22 After that last flood, the troops moved into tents because nothing at the third Fort Union had been finished at that time except one new officers quarters.

By March, 1867, the orders came through to demolish the remaining buildings known as "Old Post of Fort Union" except those necessary for housing authorized laundresses and stabling horses and mules. Any woodwork that could be salvaged from the demolition would be turned in to the depot quartermaster. The orders stated the "Old Post" but failed to mention the buildings around the "Old Post". A report recountered that a number of people still living in the out lying structures are causing problems. The inspection stated:

"There are always a lot of Mexicans and unknown Americans harbored around these buildings, Gambling, Drinking, and Prostitution, seem to be the principle use to which many of these rooms are appropriated, and soldiers of the Garrison are enticed and harbored there to carouse all night".23

In April 1867, these buildings were demolished. Like much of the first fort, the army salvaged building materials from the fortification, for re-use in the third fort.

William Shoemaker was handed the task of building the Fort Union Arsenal. Shoemaker was appointed Ordnance Storekeeper in 1841, and then appointed Captain and Ordnance Storekeeper in 1866. He proudly ran the arsenal at Fort Union from its inception in 1851 until his retirement in 1882. Shoemaker was constantly trying to improve his arsenal and to build permanent structures. He wrote the ordnance department in Washington in September, 1856, asking for a site to build a permanent arsenal, and to ask for appropriations for new construction as soon as possible.24 Shoemaker’s request was not approved, as well as the many requests he made following 1856.

By December of 1860, Shoemaker’s arsenal construction was still not underway. With the exception of one storehouse and magazine built of adobe, all of his buildings were threatening human safety. Finally in 1866, Shoemaker had been given formal approval for the construction of a new arsenal. He hired a local mason to build cisterns. The rain ducts of buildings were to be connected to the cisterns. He intended to have the water pass through a charcoal filter. By using this method, he would not need cast iron pipes. He estimated that the cisterns would each hold 15,000 gallons of water. Shoemaker’s construction of the third fort progressed at a rapid rate.25

In June 1869, Forts Lowell and Sumner, New Mexico, were abandoned and discontinued as military posts. All of the ordnance and ordnance stores from those forts were transfered to Fort Union Arsenal. Shoemaker knew the closing of these forts was a sign of things to come.

By 1873, the arsenal was almost complete. In a report Captain Shoemaker described Fort Union as Follows:

This arsenal is the depot for supplying the territory of New Mexico and parts of Texas, Arizona, Colorado and the adjacent Indian Territory. Fort Union Arsenal New Mexico is situated one mile due west of Fort Union on a reservation belonging to the ordnance department, one half-mile extent. The arsenal is enclosed by a wall on four sides of one-thousand-feet each. The buildings consists of two officers quarters and one set of barracks, one set of clerks quarters, one armorer, one smith shop one carpenter, one saddler shop, one main storehouse with basement, three smaller storehouses, two magazines for ammunition, one stable for public animals with corral, temporary outbuildings including, shops and storehouses. There is a well with an abundance of pure good water. Also two cisterns of eighteen thousand gallons each are always full in case of fire. The buildings, walls and outworks are of adobe, set on permanent stone foundations. The walls of all are heavy and well constructed.26

By 1882, the railroad had reached that area of New Mexico and the need for a standing army was diminishing. The railroad had taken over trade, freight and passenger operations, so the Santa Fe Trail was obsolete. Military activity in the west had slowed down so much that the depot, arsenal, and troops were no longer needed at Fort Union. Shoemaker announced his retirement on June 30, 1882, and asked permission to stay in his quarters in return for watching over the arsenal buildings. He was allowed to stay. On July 3, 1882, the army transfered lieutenant Russell to Fort Union Arsenal. Russell’s job was to abolish the arsenal and begin demolition of the structures.27

On September 6, 1886, Shoemaker died. He was still living in the house that he had built and he was still volunteer custodian of the empty arsenal buildings at the time of his death. Within three years, illegal salvage operations had started dismantling the arsenal buildings. Shoemaker had been meticulous about the quality of his construction. He had often hired talented civilian workmen who had done quality work. In 1892, six years after his death Shoemaker’s arsenal was gutted.

Fort Union reverted to the original claimants of the Mora Grant, who used the land for cattle ranching. With ranching operations came the need to keep the cattle safe. Because the surrounding area offered no shelter the animals tended to congregate around the walls of the fort in search of shade or as a wind break. After the ranch hands lost cattle to collapsing walls, they decided to bulldoze the most hazardous areas. In 1949, bulldozer operator Lois Timm filled in all the cisterns and wells. He also knocked down about twenty chimneys to prevent them from falling on cattle. He worked his dozer in both the third fort and arsenal areas.28

No battle was ever fought at Fort Union. Fort Union may have lacked the flair and excitement of a cavalry charge, or the heroics of an infantry platoon. But the men who served there supplied the southwest with much needed goods and kept the Santa Fe Trail open. Without Fort Union and the men behind the scene, there would have been neither posts or battles nor southwest expansion.
