March 23, 1863. Marching orders.

In the last week of March, General Casey moved the headquarters of his division from Washington to Centreville, accompanied by a large portion of his command, and the three Vermont regiments which had been for two months at Fairfax Station were moved forward – the Fourteenth joining the Twelfth and Thirteenth at Wolf Run Shoals, and the Fifteenth and Sixteenth going to Union Mills. Colonel Blunt at this time removed his headquarters to Wolf Run Shoals. ~ 2 George Grenville Benedict, Vermont in the Civil War 430-31 (Burlington Vt 1888)
  
"March 23. Marching orders have been received again to-day, and the boys are very much rejoiced, for the camp is getting very dull. We have been in this camp about two months, without having been called out in line of battle once; but have accomplished a good deal in building corduroy roads, and guarding property. We have also been put upon drill most of the time when the weather was favorable for it, with the exception of the last two weeks, which have been devoted to digging rifle pits, with which the Station could be defended, in case an attack should be made." ~ J. C. Williams, Corporal, Co. B, 14th Regiment, Life in Camp, 98 (1864)

"Fairfax Station, March 23rd, 1863 

"Tomorrow morning at 5 o’clock our regiments move - the 15th and 16th southwesterly to Union Mills, the present running terminus of the Alexandria and Orange R. R., and seven miles beyond the station on the same road toward the interior. 

"We shall then be “in front” and have picket duty on Bull Run, in face of whatever enemy may be there. Here “picket duty” will mean 
something, and I shall have to be Field Officer of the day twice a week. I am glad of the change. 

"The 14th go to Wolf Run Shoals and there join the 12th and 13th. They will be six miles southerly from the station and about five miles from us - the three places being at the angles of a nearly equilateral triangle Fairfax Station the apex and the picket line the base."  ~ Lt. Col. Charles Cummings, Sixteenth Regiment, Letters  March 23, 1863. VHS.
