During his time in the United States Congress, James Sidney Rollins introduced a bill to build a railroad and a telegraph line from Missouri to California. The bill eventually passed as the Pacific Railway Acts of 1862. He voted for the Morrill Act of 1862 that provided funding for state agricultural colleges. He served on the commerce committee and on the committee on expenditures in the war department. He voted against allowing African-Americans and Indians to enlist in the war. He reasoned that moderate Southerners would be offended and more likely to join the rebel cause. He objected to the Emancipation Proclamation on the grounds that it was legally void and defensible only as a military necessity.
During a congressional break in the fall of 1864, Congressman Rollins returned to his home state. On September 27 as he, the Boone County sheriff, and several others from Columbia were traveling north by stagecoach to a Democratic convention in Macon, Missouri, “Bloody Bill” Anderson’s men attacked and robbed the stage in Centralia. As the outlaws questioned their captives’ loyalty to the Confederacy, a better prize pulled into the station – a train filled with Union soldiers. Anderson’s men abandoned the four-horse stage for the iron horse. The stage passengers fled. A local hotel owner whom Rollins had helped years before recognized him, called him to the hotel and hid him. The guerillas shot 23 Union soldiers.
After escaping the Centralia, Missouri massacre, James Sidney Rollins returned to Washington, DC. The most pressing issue in Congress in 1864 was the 13th Amendment to end slavery in the United States. On April 8, the Senate passed the constitutional change on the first vote. But the House of Representatives defeated the bill twice. Rollins was among the dissenters. Shortly before the third vote, Abraham Lincoln called Rollins to his office. Both were long-time Whigs who had attended conventions together and both had worked as railroad attorneys. Lincoln asked Rollins to support the 13th amendment to help preserve the Union. For the sake of Union, Rollins gave a rousing speech on the floor of Congress on January 13, 1865. With his support, the amendment passed with the needed two-thirds majority.
Concluded in Part IV
 In the afternoon, in the field of a nearby farmer, 120 soldiers of the 39th Missouri Infantry confronted Anderson’s men. The guerrillas killed 107 in what came to be known as the Battle of Centralia.
 In 2007 a great-great-grandson established a $25,000 endowment fund to the Black Studies Program at the University of Missouri entitled the “The James S. Rollins Slavery Atonement Endowment.”
