Some of you all might be interested in this.

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. Ever foremost in battle and last in the retreat, his death would be regretted by all who mourn the loss of the good and the brave. At the same time that Colonel Shanks forced the passage of the Osage as stated, Colonel Gordon, of the same division, forced its passage at Castle Rock, and the division bivouacked that night seven miles from Jefferson City.
