An Unfortunate affair.

We saw yesterday evening, at the undertaker's establishment of Maj. Williams, the body of a gallant and heroic Lieutenant — McMahon, of a Mississippi regiment — who, we were informed, had been shot by a citizen of Dumfries, whose name we were unable to learn. The shooting is said to have occurred under the following circumstances: Lieut. M. had been sent by a superior officer to get a horse from this citizen. He offered both to buy or to hire the horse, both of which offers were refused. He then returned and reported, when he was ordered to impress. This he returned to do, when the owner of the horse deliberately shot him. It is reported that the citizen has since been hung. This, however, is not well vouched for. He has, however, been arrested and placed under a strong military guard.--Fredericksburg Recorder, 7th.
