Colorado Civil War Soldiers Index
This index contains the names of 7,500 men who served in the Civil War from Colorado.
When President Lincoln called for volunteer soldiers to supplement the regular army, Colorado responded. Eventually, nearly 4,000 men from the Colorado Territory served in the volunteer Union forces authorized by the United States War Department. Hundreds more served in militia companies, authorized by the territorial governor, most of which were formed to fight Indians rather than Confederates.
The National Archives Index contains 8467 names of Colorado men, all Union. Because of the reorganization of the troops during the war, and many of the names having alternate spellings and some with initials only, there are many duplicates.
