Something I found that may be interesting
On the 6th Brigadier-General Shelby sent a force under Colonel Shanks to destroy the bridge over the Osage on the Pacific Railroad, which was successfully accomplished. A passage was then forced by him across the Osage six miles below Castle Rock. The enemy disputed the passage warmly, but in vain. In this action the gallant Colonel Shanks received a severe, if not a mortal wound, and, left in the hands of friends to be cared for, he afterward fell into the possession of the enemy, and is reported to have since died, a loss to be greatly deplored.
