June 4, 1863 The 5th Mich. Cavalry Rgt. or at least part of it was engaged on June 4, 1863 skirmishes on Lawyer's Road near Fairfax Court House and Frying Pan, Va.

HEADQUARTERS STAHEL'S CAVALRY DIVISION
Fairfax Court-House, Va., June 4, 1863
SIR: All is quiet along our lines and in front on the Orange and Alexandria Railroad.

This morning at 5 o'clock, when the relief passed, our pickets were attacked oh the Lawyers' road by guerrillas. Colonel Gray at once started with about 120 men in search of them, but could find nothing of them in those woods. He then went on to scout the whole country, and, when he passed Frying Pan, his rear guard was attacked by about 100 rebels, who were hidden in a thick wood. Colonel Gray turned his column and charged the rebels, who fled in great haste through the woods. He followed them up to Aldie, and from there returned, via Dranesville.

Our entire loss is three wounded, and some horses wounded. We captured their surgeon, Dr. Alexander.
Respectfully,
JUL. STAHEL, Major-General.
Lieut. Col. J. H. TAYLOR, Chief of Staff, and A. A. G., Department of Washington.

NOTE: The Col. Gray mentioned is George Gray of 6th Mich. Cavalry Rgt. but its not unreasonable to assume that he had detachments from other Michigan cavalry regiments. There is no mention of any Union soldiers being captured. It may be that Robert was wounded here and captured later.
