On page 50 of WIley Britton's "The Union Indian Brigade in the Civil War", Colonel Weer is noted as commanding officer of the 10th Kansas Cavalry.

On page 62, Britton writes: "In the political deals that were made, Lieutenant-Colonel James G. Blunt, of the Third Kansas Infantry, which had been broken up, was appointed Brigadier General of Volunteers and assigned to the command of the Department of Kansas, including the Indian Territory, with headquarters at Fort Leavenworth, the base of supplies for the department, and, as his presence was required at headquarters to make arrangements for furnishing his troops in the field with the needed supplies, which would have to be transported by wagon trains for a distance of over two hundred miles and over streams that had not been bridged, he was unable to accompany the expedition. [GOOD GRIEF, GERTRUDE! THAT'S 107 WORDS IN ONE SENTENCE!!!] In the absence of General Blunt, the command fell upon Colonel Weer, the senior colonel, who had been, up to entering the army, a lawyer of some ability in Wyandotte, and had a good military bearing, and would have been an efficient officer except for the fact that he was addicted to the liquor habit, which was frequently so pronounced as to unfit him for having command of troops in the field.

"The regimental commissary sergeants made out requisitions on the division commissary for rations to issue to the regiments to which they belonged, and the requisitions had to be approved by the division commander, and it so happened that one time when the command was to make a night march so as to strike the enemy at daylight the next morning, that one commissary sergeant was directed to have the rations issued to the companies of his regiment by dark. He took the requisition to Colonel Weer's headquarters to have him approve it; but was unable to see him, that officer being drunk in his tent; the errand was repeated three or four times, and finally just before midnight his approval was secured; his drunken condition caused a delay of several hours in the movement of the troops whose requisition for commissary supplies was to be filled."

There are more references to him in the following pages and chapters; however, as I recall from last year's reading, the Colonel was arrested for being consistently drunk while on duty and unable to fulfill the responsibilities of his command.
