A typical frontier fort from the 1840s. No actual drawings of Fort Des Moines are available. |
In the spring of 1843, the U.S. Army sent a detachment of
soldiers into the Iowa wilderness to build Fort Des Moines No. 2. The first
fort, built near Montrose Hill in 1837, had failed after a few years.Captain James Allen, a West Point–trained topographical
engineer, led the mission. His men from the 1st U.S. Dragoons left Fort Sanford
and Fort Dodge, followed the Des Moines River, and stopped at a muddy fork
where two brown rivers met. Allen later wrote, “The junction of the Raccoon and
Des Moines Rivers presents high and dry ground, and is well suited for a post
commanding the valley.”
The soldiers built a stockade of cottonwood logs
enclosing about four acres. Inside stood two blockhouses, a storehouse,
stables, and several cabins. In the center lay a parade ground where the men
drilled, repaired equipment, and waited for mail that rarely came.
The fort’s purpose was to oversee the Sauk and
Meskwaki tribes. A few years earlier, the United States had compelled them to
cede their eastern Iowa lands under the Treaty of 1842. Allen’s official orders
stated his duty was “to prevent the intrusion of whites upon Indian lands, and
to keep the Indians from crossing eastward.”
