branch of the service having been brought into disrepute by the worse
than futile efforts of others, his superior officers at first refused
him permission to engage in so questionable an enterprise. Finally,
however, General Stuart gave Mosby a detail of nine men from the regular
cavalry with which to experiment.

At that time the two main armies operating in Virginia were confronting
each other near Fredericksburg. To protect their lines of communication
with Washington, the Federals had stationed a considerable force across
the Potomac, with headquarters at Fairfax Court-house. They also
established a complete cordon of pickets from a point on the river above
Washington to a point below, thus encompassing many square miles of
Virginia territory. Upon these outposts Mosby commenced his operations.
The size of his command compelled him to confine his attacks to the
small details made nightly for picket duty. But he was so uniformly
successful that when the time came for him to report back to General
Stuart, that officer was so pleased with the experiment that he allowed
Mosby to select fifteen men from his old regiment and return, for an
indefinite period, to his chosen field of operations.

His first exploits had been so noised abroad that the young men from the
neighboring counties and the soldiers at home on furloughs would request
permission to join in his raids. He could easily muster fifty of these,
known as "Mosby's Conglomerates," for any expedition. The opportunity

great vigor he renewed his attacks upon the Federal outposts. As a
recognition of one of his successful exploits, the Confederate
government sent him a captain's commission with authority to raise a
company of partizan rangers. The material for this was already at hand,
and on June 10, 1862, he organized his first company. This was the
