Any references showing association of "Asboth Rifles" with any particular MO. units would be appreciated. The following extract has been copied from "eHistory" as a result of a Google search. The term of the 3Mo Volunteers had expired at the time of the extract, with Schafer having assumed command from Boernstein, and so the extract seems credible, although the accuracy of eHistory is not self-authenticating.

"Numbers 2. Report of Colonel Frederick Schafer, Second Missouri Infantry.

HDQRS. SECOND INF'Y, ASBOTH RIFLES, MO. VOLS.,
Potosi, Mo., August 12, 1861.

By order received of Major-General Fremont, I hereby report myself to you.

I arrived here about 8 o'clock this morning, but did not find any more rebels here. There were two companies of Colonel Hecker's regiment stationed here, under command of Colonel Kallmann, U. S. R. S. The information received from Captain French, of the Home guards of this place, about the fight which took place here last Saturday [10th], is as follows: On Saturday evening, about 6 o'clock, the Home Guards were attacked by about 150 mounted rebels. At the time of the attack there were only about 20 Home Guards on duty; the rest were out protecting the bridges on the road. That brave little band of Home Guards drove those 150 mounted rebels from the town, taking several of their horses and wounding five rebels. The Hone Guard had five of their men also wounded, but not seriously. When I arrived in this town, the two companies of Hecker's regiment, U. S. Army, left to join their regiment, and took 17 prisoners with them. The town at present is all quiet.

Your respectful and obedient servant,

FRED. SCHAEFER,

Colonel, Commanding Second Regiment Missouri Volunteers."
