CAMP BEYOND RocKvuLn. Nd. Monday Sept q, 1862
Report came TO Washington Saturday night
that the Rebels, having crossed tie Potomac, Lad
occupied Poolesville in force, and were moving to
the SOUTH that pickets had been driven in
during the day, and twenty-nine of the LEI Msssa-
chusetts Cavalry had been captured and that Sum-
ner was in line of battle momentarily expecting On
attack.
The message was semi official, and was conf med
by the movement Of troops in the streets which
began soon after Regiment after regimen, marched
late at night by Wizards, cheered By the crowds
which thronged the sidewalks till midnight Aews
had spread also in the afternoon that Pope had been
relieved from command, that Mcdowell had been
Suspended, and that Burnside was to lead the COL
umns marching for Maryland. Everything looked
like battle.
The road next morning was filed with advancing
columns Of troops and the inevitable trains Of veg
