DENMARK AND THE DUCHIES,

We have letters and papers from Hamburg of the
27th inst.

The Schleswig-Holstein troops were then still at
Sebestedt, where, after heroic efforts, Van der Tann
and his corps bad succeeded in reaching his main
body. With this corps and the troops remaining
under Willieen the Duchies still have an army of
22,000 to 24,000 men.
The Danes spent the day of the 26th in gathering
up the dead on the field of battle. Their wounded
are, it seems, in considerable number.
The morning train from Rendsburg brought the in-
tellirnoe for the Harnburgh Borsenhalle, that the
Danish general bad offered a truce of three days to
General Willisen, but which he had refused. The
Danish troops had. on the 26th, advanced within •
few miles of the Eider, to Cropp.

The following further particulars will be read with
interest:

(Front the Hansburgh Nachrichten, Jot, 27.)

The lose on both sides is very great. Several
officers, on a rough calculation, estimate it at above
10,000 men. Four guns fell into the hands of the
Dates, and four of the Danish field-pieces were driven
I into a morals, and spiked by the SchleswirHol-
'Miners. One regiment of Danish Hussars is said
to have suffered a great loss from the grape-shot of
our artillery.
No official reports have u yet been published, but
we have received the following particulars from a
highly respectable source, although we do not pledge
ourselves u to their accuracy on every point:
The centre of the Schleswig-Holstein army was
posted at Idetedt, under the commend of General
Willisen ; the right wing, under Von der Horst, ex-
tended from Wedelspang as far u the Sc.bleir and the
left wing, under Baudissin, until he was obliged to
retire in consequence of his wound, when the com-
mand devolved upon Von der Tann, extended from
Helligbeck as far as the Treene, near Sollbroe, the
whole army forming a semi-circle, the most promi-
nent point being the centre, at Idstedt.
At the commencement of the engagement the
left wing was very severely pressed, bat the Danes
soon threw all their force on our centre, which, after
a most obstinate contest, was at length compelled to
retreat in the direction of Schleswig, the right wing
also accompanying it, but maintaining the same
relative position to the centre at 6 o'clock in the,
evening as at 6in the morning. After the retreat of
the centre, which defended itself with the utmost
bravery, the left wing also commenced a retrograde
movement, covering the retreat. The cavalry is said
to have been but little engaged, and to have lost only
three men.

The following infantry officers are among the
killed :—Major Brunckhof. Lieutenants—Haller-
stein, %Bergdorf, Haider, and Sander.
And the following are among the wounded :
Major-General Baudissin (slightly ; Major Lutzow
(slightly); Captains—Unruh, Boner, and Carrel;
Lieutenants—Schnobel, Hilliger, Duddiog, Wilding,
and Jenner. _ _

The infantry took off their knapsacks, Sze., to enable
them to fight the easier, and, having saved the whole
of their baggage, it will at once be seen with what
admirable order the retreat must have been conducted,
The troops evacuated Schleswig, and commenced
their march towards the month singing their national
songs.
