Attached to Defenses of Nashville & Northwestern Railroad, Department of the Cumberland, to August 1864.
Ordered to Join Army in the field and march to the Chattahoochie River, Georgia, August 15–25.
The 1st Missouri Engineers figured largely in Sherman's March to the Sea and Carolinas Campaign.
In addition to building roads and repairing railroads and bridges, the regiment provided "pontooneer" detachments which transported and constructed mobile temporary bridges which sped the movement of Sherman's units.
[2] Confederate General Joe Johnston paid tribute to the 1st Missouri (and Sherman's other engineers) when he said: "When I learned that Sherman’s army was marching through the Salk swamps, making its own corduroy roads at the rate of a dozen miles a day, I made up my mind that there had been no such army in existence since the days of Julius Caesar."
(This figure includes the casualties suffered by the "Bissell's Engineer Regiment of the West" before it was consolidated with the 25th Missouri Infantry to form the "1st Missouri Engineers".)
