The Colorado Territory was formally created in 1861 shortly before the bombardment of Fort Sumter sparked the American Civil War. Although sentiments were somewhat divided in the early days of the war, Colorado was only marginally a pro-Union territory. Colorado was strategically important to both the Union and Confederacy because of the gold and silver mines there as both sides wanted to use the mineral wealth to help finance the war. The New Mexico Campaign was a military operation conducted by Confederate Brigadier General Henry Sibley to gain control of the Southwest, including the gold fields of Colorado, the mineral-rich territory of Nevada and the ports of California. The campaign was intended as a prelude to an invasion of the Colorado Territory and an attempt to cut the supply lines between California and the rest of the Union. However, the Confederates were defeated at the Battle of Glorieta Pass in New Mexico and were forced to retreat back to Texas, effectively ending the New Mexico Campaign.
Galvanized Yankees was a term from the American Civil War denoting former Confederate prisoners of war who swore allegiance to the United States and joined the Union Army. Approximately 5,600 former Confederate soldiers enlisted in the United States Volunteers, organized into six regiments of infantry between January 1864 and November 1866. Of those, more than 250 had begun their service as Union soldiers, were captured in battle, then enlisted in prison to join a regiment of the Confederate States Army. They surrendered to Union forces in December 1864 and were held by the United States as deserters, but were saved from prosecution by being enlisted in the 5th and 6th U.S. Volunteers. An additional 800 former Confederates served in volunteer regiments raised by the states, forming ten companies. Four of those companies saw combat in the Western Theater against the Confederate Army, two served on the western frontier, and one became an independent company of U.S. Volunteers, serving in Minnesota.

Kirby Smith, as the Confederate commander of the Trans-Mississippi Department, assigned Gordon to duty as a brigadier general. The Confederate government took no action on the appointment and Confederate President Jefferson Davis did not officially appoint and nominate Gordon to the rank of brigadier general because the Confederate Senate last met on March 18, 1865, and Davis was captured by Union troops on May 10, 1865. Although he was only aged 40 at his death, Gordon survived the war by little more than a year.

The Battle of Egypt Station was an engagement in Mississippi that took place during a successful Union cavalry raid during the American Civil War. A 3,500-man Union cavalry division under Brigadier General Benjamin Grierson defeated Confederate troops led by Franklin Gardner and Samuel J. Gholson. Grierson's raiding cavalry left Memphis, Tennessee on 21 December and first demolished a Confederate supply depot at Verona. Moving south while wrecking bridges and track along the Mobile and Ohio Railroad, the Union raiders encountered the Confederate defenders at Egypt Station. After their victory, Grierson's cavalry headed southwest to Vicksburg which it reached on January 5, 1865. The raiders destroyed a large amount of Confederate supplies and also damaged the Mississippi Central Railroad. Some of the men captured by Grierson's raiders proved to be former Union soldiers who volunteered to fight for the Confederacy rather than languish in prison camps. When John Bell Hood's army retreated into northern Mississippi after the Battle of Nashville, it was unable to obtain supplies because Grierson's raiders had damaged the railroad so badly.
