Editing Phelps County, Missouri (section)

===Civil War===
The railroad ran its first train on December 22, 1860, making Rolla the terminus of the road. Until the continuation of the Frisco, all goods were loaded on wagons and transported to Springfield and south and west on what is now U.S. Highway 66 (Interstate 44). During the [[American Civil War]], Rolla was an important military post, hosting up to 20,000 Union troops. The Phelps County Court House was transformed into a hospital during the war.

In April 1861, [[Fort Sumter]] was fired upon and a decision was made to support the [[Confederate States of America|South]]. On May 10, the Circuit Court session saw a heated debate of secession, which caused a breakup of the proceedings. As the story goes, Circuit Court Judge James McBride soon departed to assume command as a Confederate general under Sterling Price. Outside the courthouse, a group of men drew down the United States flag and raised a Confederate flag, which had been hastily pieced together by the women of Rolla. The tension was thick when the group then moved to the newspaper office of Charles Walder, a Union supporter and editor of the ''Rolla Express''. Walder was forced to close his shop and cease printing. Southern sympathizers patrolled the town day and night, often ordering Union sympathizers to leave town.

On June 14 of that year, General Franz Sigel arrived by train with his 3rd Missouri Infantry and took over the town. From that day until the close of the war, Rolla was in Union hands.

The 13th Illinois Infantry Regiment, under Colonel John B. Wyman, was brought in to guard Rolla and the Pacific Railroad's terminal. It was this regiment that did the basic planning and building of Fort Wyman, although other regiments completed it. [[President of the United States|President]] [[Abraham Lincoln]]’s personal order was that Rolla should be held at all costs. Being situated at the terminus of the railroad, military wagon trains went out from Rolla to all Union armies stationed southwest in [[Arkansas]], [[Hartville, Missouri|Hartville]], and Springfield and northwest to the Linn Creek area, now known as [[Lake of the Ozarks]].

After General Price's defeat at Pea Ridge in March 1862, several troops that were organized by Governor Jackson returned home. Confederate sympathizers, unwilling to profess their loyalty and support to the Union after the battle, were treated harshly. One example is the shooting of former Presiding Justice Lewis F. Wright and four of his sons in 1864, after being taken from their homes for "questioning."

Rolla was an important site during the Civil War because the southwest branch of the Pacific Railroad ended here. Thousands of Union troops and their supplies came to Rolla by train from St. Louis and then were transferred to wagon trails to go to the battles of Wilson Creek in Springfield and Pea Ridge and Prairie Grove in Arkansas, plus a number of other smaller skirmishes. The railroad had arrived in Rolla in 1860 but the outbreak of the war halted the westward expansion of the line.

The town of about 600 civilians had a large population of Union troops at that time. Since the Union forces seized control of the town early in the war, they had a big impact upon the town and its operation.

The town was a busy place for the visitor. In 1860 sugar sold for 10 cents a pound, tobacco for 30 cents a pound. Whiskey went for 25 cents a gallon. City lots sold for $25 per lot. The Courthouse was used as a hay storage barn and later as a hospital for wounded soldiers. After the commanding general of the Union Forces, General Nathaniel Lyon, was killed at the Wilson's Creek battle near Springfield, his body was brought to Rolla to be transported back East for burial. Old town Rolla was located along Main Street near the Courthouse. The business district moved to Pine Street in the late 19th century.

Following the Union defeat at Wilson's Creek on August 10, 1861, the Union Army fell back to Rolla and began building an earthen fort on a hill alongside present Highway 63 about a mile from the Courthouse. The rectangular fort had a dry moat around the perimeter with 32-pound field pieces located on each corner of the fort to cover any attack on Rolla from the south. It was named Fort Wyman after Colonel John B. Wyman. Fort Dette was a more detailed fort that was constructed in 1863 on what is now the campus of Missouri University of Science and Technology. It was constructed in a cross shape with positions for both 24-pound cannons and ports for individual rifle fire.
