Later accounts from General M'Clellan's head-
quarters state that Tuesday last was chiefly passed
in deploying the forces and gaining positions ; but
on Wednesday a severe battle was fought, lasting
from dawn till dusk. The result of the battle was
indecisive, but the superiority of position remained
with the Federals ; their loss is estimated at from
6,000 to 10,000 men. Federal General Mansfield
was killed, and Generals Hooker, Dureza, Sumner,
Meagher, Max, Weber, Dana, Hartauff, Richard-
son, Sedgwick, French, Ricketts, and Rodman
were wounded. The loss of Federal generals and
field officers is said to be so large as to be unac-
countable.

Little beyond skirmishing occurred on Thurs-
day. General M'Clellan officially reports ou Fri-
day morning that the enemy abandoned his position
on Thursday night, leaving dead and wounded on
the field ; and says :.--" I do not know if the enemy
is falling back to an interior position, or crossing
the river. We may safely claim the victory for
ours."

In a Liter despatch he reports that General Plea-
santon is driving the enemy across the river, and
says :—" Our victory was complete. The enemy
is driven back into Virginia. Maryland and Penn-
sylvania are now safe."
The newspaper accounts state that the Con-
federates commenced crossing the Potomac at
Shepherdstown Bridge, and two fords above and
below it, early on Thursday night.
During the night General M'Clellan advancDd a
battery and shelled the Confederates from the sur-
rounding heights. Early on Friday morning
General Pleasanton pursued them with two
batteries and two regiments of infantry, and cap-
tured some of their ammunition and supplies and a
small portion of a South Carolina brigade.

General Stonewall Jackson conducted the Con-
federate retreat into Virginia, and the whole Con-
federate army appears to have crossed the Pot>
mac, with but alight loss of men, waggons, and
artillery.
The Confederates retreated in the direction of
Winchester.

A considerable Federal force, under Generals
Siegel and Heintzelman, is on the Virginia side of
the Potomac, and speculation is rife whether
this force will interfere with the Confederate
retreat.

General M'Clellan'a army crossed Anty -em
Creek, and is massed between that position and
the Potomac, opposite Shepherdstown. It was
supposed that ItI(Clellsn would cross the
Potomac.

The capture of the Confederate General Long-
street is not confirmed.

The Federal garrison at Mumfordsville, Ken-
tucky, numbering 4,000 to 5,000, with 10 pieces of
artillery, surrendered on the 17th to the Confede-
rate General Bragg, whose forces numbered 30,000.
The reported investment of Charleston is officially
denied.

The Federal gunboats have destroyed Prentice,
The Confederates are concentrating at Golds-
borough, with the intention of attacking Newburn,
North Carolina.

for Washington.

the blockade of Mobile.

(Par Norwegian by telegraph to Father Point and from
Londonderry.)

General Burnside occupied Harper's Ferry on
Tuesday last, driving the Confederates out, and
pursuing them to Martinaburgh. He afterwards
crossed the Potomac, and was in the engagement
of Wednesday under M'Clellan.
The Confederates all succeeded in crossing the
Potomac on Friday morning, saving their transports
and all their wounded, except 300.

The Confederates are still visible in force on the
Potomac shore, opposite M'Clellans position, and
have posted artillery to prevent the Federals from
crossing.

The Federal/ estimate the Confederate loss at
18,000 to 20,000 men.
