On the 28th, Ricketts' Division was at Thoroughfare Gap, sent there to
check the advance of Longstreet's Corps on its way to join Jackson at
Manassas.
It will be noticed that McClellan's failure in front of Richmond had
become fixed fact before this movement of Jackson's was determined
upon, and now Lee's troops at Richmond were relieved from pressure.
The march to the Gap was too late for effective service, and, on the
same night, Ricketts marched his Division from Thoroughfare Gap to join
the main army.
