from. bins, , that: there Were. flirty Cossacs - sta-
tioned in a large tavern in the middle of the 'city,
that the Magazines were guarded by veterans,
without arms, and that they were Surrounded Li
combustibles; :to whichtnatches' wre ready to be
applied the inoinenf intelligence was received that
the Gratid. Army was on its march towards Ponie,
vriez. After receiving this information, we pro-
ceeded on our route, and having reached a
little wood behind the village of Nowidwor, we
concealed ourselves there for some time. A pea-
sant, whom we surprised, informed us that there
were five Cossacks detached from Poniewiez,
quartered at the house of the landlord's steward.
These we made prisoners of without firing a shot,
and sent them in. Having reached the town,
we rested our horses for a short time, and M. de
Raven, keeping in his mind your express orders
not to lose sight of the great object, that of sat-
ing the magazines, for the sake of taking a few„
prisoners, divided his troop into small detachments,
for the purpose of immediately attacking the 'ma-
gazines, putting therfunctionaries
.to the sword,
and employed esery, method to prevent the r set-
ting them on fire. My orders were to surprise,
with twenty horsemen, the CossaCks "io the inn.
As soon as the head of our column had' reached
,
the town, we made the best of our way in. All
the inhabitants were enjoying their first sleep, ex-
cept the Russian Commissary, who was, engaged
with a select society at Pharo. Not thinking it
necessary to trouble Riyself with him, I proceeded
to the inn. The CoSsacks, awakened by the
trampling. of the horses, fired at us with their
pistols. :I ordered our men to return the fire,.
and perceiving that several CoSsacks were avail-
ing themselves of the darkness of the night to
reach the stables on foot or on horseback and es-
cape, I made the men alight. Just at this:period
M. Raven received three wounds, from a-lance, in
the thigh and the lower part of his belly, but such
of the Cossacks as were able to get away, were
almost all wounded by the hussars; who acted as
a reserve. Their .officer received a wound from
a pistol, in the thigh., of which, if I am righty in-
formed, he died about two miles from this place.
Having alighted, I gave my horse to the trum-
peter, and entered' the inn sabre and pistol in hand.
Eighteen Cossacks having stationed themselves
in a corner of rle porch, made a desperate defence,
they pushed at random with their lances. lean-
ed aloud for lights, and some of the citizens en-
deavoured to procure them, but were attacked
and preYented by the Cossacks. 1 then at-
tacked them sabre and pistol, but being ignorant
-that they could protect thepselves by means of a
staircase which led to the cellar, our aim was taken
too high, and the consequence of which was, that
we did no harm' but to the lances, which were
hacked and shattered by sabres and bullets. This
darkly combat lasted till the day broke upon
us. The non-commissioned officer, Werner, then
seizing a Russian fusee, roshed forward to attack
the Cossacks, at the point of the bayonet, in their
subterranea'n retreat. The non-commissioned of-
ficers, Pommeriet and Gabouski, followed sa-
bre in hand, and the hussar, .Stanke, who had lost
his satire by a blow of a lance, seized that of a
Cossack, crying out' to, his comrades, ".1 shan't
let go my hold, cut the Co rack's hands of" Upon
this the Cossacks threw, down their lances, and
begged for quarter.
Two of them were killed, a'few wounded, and
the remainder made prisoners.
The veterans who were stationed as a guard on
the magazines, were without krins, hat some of
them, having pinked up muskets, fired on my peo-
ple. 1 overlooked this, however, and forbore to
'charge the old men, but took them all prisoners 3'•
they arc 120 in number.
This, Colonel, is the detail of au affair of, per-
haps, not much importance, butsvhich will prove
to you that the valour and discipline of out' regi-
ment 4s not decreased since the seven years war.
I beg leave to recommend to you the three non-
commissioned Officers and the hussar mentioned
in my reporc. • ,
Poniewiez, July 6, 1812.

LEIPZIC, JULY 18.—The intelligence received
from the Grand French army, confirm its rapid
progress. Its different coluthns scarcely meet
with any resistance in their quick advances. The
Duke of TARENTUM has seized upon Courland,
where he found considerable magazines. It was
'thought the Russians .4ould have attempted to
defend themselves upon the river Aa, but they
abandoned it to retire behind the Duna.

The column which, by Methel, has entered the
Russian territory, after having occupied. Polan-
gen, winded along the ports of the Baltic, and
has, it •is said, found considerable quantities of
English goods in the ports of Licbau, Hasen-
pod), and Windaw.
• The Russian troops, who occupy the lower part
of the Duna, are not numerous ; , they are spread
between Kreutzbourg and Riga. The Corps
d'Armee of the Duke of TARENTUM is now march-
ing to the east of Courland.
A report has been in circulation that the French
had entered Rigs, but it is preinature, and we
have, no official advice of it. Maishal the Duke
of REGGIO'S corps is marching from Wilkoinir,
where Prince WITGENSTEIN had his head-quar-
ters, to Widzy, in which were those of the Grand
Duke CONSTANTINE. Widzy is at some distance
from Dunabourg and Bream, I,vhcre the centre
of the Russian army passed ' the Duna. The
Duke of EL' CRINGEN, with his corps, is marching
to it.

The Russians are erecting entrenchments at
Dunabourg and between that town and the Duna;
it appears that it is in that position.where they
will wait for the French Army.
At the departure of the last courier the French
head-quarters were still at Walla, but it was not
expected they would remain there long.
