Headquarters Cavalry Brigade,
Fairfax Court-House, Va., March 3, 1863.
Sir:—By order of Col. R. B. Price, I directed, on the night of the 1st instant, a reconnoissance to go in direction of Aldie.
The officer who commanded this reconnoissance was Major Joseph Gilmer, of the Eighteenth Pennsylvania Cavalry. He had two hundred men. The orders to him were to proceed carefully, and send back couriers through the night with information whether they saw any enemy or not. This last order was disobeyed. They were not to cross Cub Run until daylight, and then try and gain all information possible by flankers and small detached scouting parties.
Major Gilmer went to Middleburg, and, while returning, the videttes of the First Vermont Cavalry noticed a part of his advance and prepared to skirmish. The advance fell back toward Aldie. Major Gilmer, instead of throwing out a party to reconnoitre, turned off with nearly the whole of his command in the direction of Groveton, to gain Centreville. The horses returned exhausted from being run at full speed for miles. A few of Major Gilmer's men left his command and went along the Little River turnpike toward the Vermont detachment. They reported that the men seen were a part of a scouting party under Major Gilmer, and that no enemy were in Aldie. Capt. Huttoon then entered the town, and halted to have the horses fed near a mill. Immediately beyond was a rising ground which hid the guerillas. While the horses were unbridled and feeding, the surprise occurred. As both the officers have been captured, and as the detachment was not under my command, and is not attached to this brigade, I have no means of receiving any official or exact report from them, nor is there any one belonging to that detachment here. All men belonging to this detachment seem to have fought well; the enemy did not pursue them; they fell back in good order.
Major Gilmer, when he returned, was unable to make a report to Lieut.-Col. [John S.] Krepps, who during the time I was confined from sickness, had charge of the camp. I ordered Major Gilmer under arrest early this morning, and have sent to Col. R. B. Price charges, of which the annexed is a copy. Major Gilmer lost but one man, belonging to the Fifth New York Cavalry, who was mortally wounded by the enemy and afterwards robbed. He was away from the command and on this side of Aldie, his horse having given out. The enemy seemed to have been concealed along the line of march and murdered this man, when returning, without provocation.
I have the honor to be, very respectfully, your obedient servant,
ROBT. JOHNSTONE,
Lieut.-Col. Commanding Cavalry Brigade.
Capt. C. H. Potter,
Assistant Adjutant-General.

No. 229. | } | Washington, July 23, 1863. |
I. Before a General Court Martial, which convened in the city of Washington, D.C, March 27, 1863, pursuant to General Orders, No. 20, dated Headquarters Cavalry, Defences of Washington, near Fort Scott, Virginia, February 2, 1863, and Special Orders, No. 146, dated February 10, 1863; No. 150, dated February 16, 1863; No. 161, dated March 6, 1863; and No. 164, dated March 21, 1863, Headquarters Cavalry, Department of Washington, and of which Colonel E. B. Sawyer, 1st Vermont Cavalry, is President, was arraigned and tried—
Major Joseph Gilmer, 18th Pennsylvania Cavalry.
Charge I.—"Drunkenness."
Specification—"In this; that Joseph Gilmer, a Major of the 18th Pennsylvania Cavalry, he then being in the service of the United States, and while in command of a reconnoitring party, on the second day of March, 1863, was so intoxicated from the effects of spirituous liquors as to be incapacitated to perform his duties in an officer-like manner. This at or near the village of Aldie, in the State of Virginia."
Charge II.—"Cowardice."
Specification—"In this; that Joseph Gilmer, a Major in the 18th Pennsylvania Cavalry, he then being in the service of the United States, upon the second day of March, 1863, did permit and encourage a detachment of cavalry, in the service of the United States, and under his command, to fly from a small body of the 1st Vermont Cavalry, who were mistaken for the enemy, without sending out any person or persons to ascertain who they were, or what were their numbers; and that the said cavalry under his command, as above stated, were much demoralized, and fled many miles through the country in great confusion and disorder. This near Aldie, in the State of Virginia."
To which charges and specifications the accused, Major Joseph Gilmer; 18th Pennsylvania Cavalry, pleaded "Not Guilty."
Finding.
The Court, having maturely considered the evidence adduced, finds the accused, Major Joseph Gilmer, 18th Pennsylvania Cavalry, as follows:—
Charge I.
Of the Specification, | "Guilty." |
Of the Charge, | "Guilty." |
Charge II.
Of the Specification, | "Guilty." |
Of the Charge, | "Not Guilty." |
Sentence.
And the Court does therefore sentence him, Major Joseph Gilmer, 18th Pennsylvania Cavalry, "To be cashiered."
II. The proceedings of the Court in the above case were disapproved by the Major-General commanding the Department of Washington, on account of fatal defects and irregularities in the record. But the testimony shows that the accused was drunk on duty, and brought disgrace upon himself and the service. The President directs that, as recommended by the Department Commander, he be dismissed the service; and Major Joseph Gilmer, 18th Pennsylvania Cavalry, accordingly ceases to be an officer in the United States Service since the 20th day of July, 1863.
By order of the Secretary of War:
E. D. TOWNSEND,
Assistant Adjutant-General.
