FRANCE.
THE CAMP AT CHALONS.
The correspondcnt of the Constitutionnel writes
as follows :

" CAMP AT CHALONS, AUG. 18.

" At the experiments with the rifled cannon yes-
terday the Emperor, the better to judge of their
precision, took up his position not far from the
butts. This morning a large concourse of people
came in from all quarters to witness the military
high mass. It was celebrated with the usual pomp ;
the Emperor, the Prince Imperial, the Minister of
War, General Fanti, the Prefect of the Marne, the
military household of his Majesty, a numerous cor-
tege of generals and officers, attended the service
near the altar.
" After mass on the terrace in front of the
Imperial pavilion various foreign officers were
presented to his Majesty. The Emperor presented
the cross of the Legion of Honour to an Arab
chieftain who is here. The Arab was much moved
when the Emperor himself fastened it to his
burnous. Before retiring to his apartment the
Emperor had some conversation with Vivier, the
celebrated artiste. Various generals and officers of
distinction have arrived. Nalim Pasha has left for
Paris. Tomorrow we expect the Prince of Baden
and Marshal Canrobert.

" The division of Cuirassiers from Nancy and
Luneville has arrived at the camp, and has taken up
a position to the right, not far from the division of
Lancers.
" Grand manoeuvres are announced for to-mor-
row in the plain, at 5 a.m., at which all the troops
will be present.

" AUG. 19.

"This morning, at 5 o'clock, the troops were all
in motion for the grand manoeuvres I announced
to you.

" An attack was to be made upon the so-called
white works—fortified mounds—which are within
the enceinte of the camp, near the road from Suippes
to Baconne. Those works were occupied by the
enemy.

"A corps d'armee is supposed to advance by Bar-
le•Duc on Rheims, following the Roman road.
" On its march, as soon as its advanced posts
reach the heights of the farm at Bony, it perceives
the enemy in position on its right.
" The Commander-in-Chief reconnoitres the posi-
tion, and ascertains that the enemy has a footing
on the plateau of the white works, where he has
fortified himself. As the troops forming the re-
connaissance approach, the enemy's artillery opens
fire upon them.
" The Commander of the chief corps d'armee
having carefully ascertained the enemy's position,
does not intend attacking it in front, as he should
thereby expose himself to heavy loss. Attacking
on the left, his line of retreat would bo endangered.
He, therefore, resolves to attack the enemy on the
right of his defences. This determination taken, he
endeavours to manceuvre so as to flank the left
of the enemy's position, at the same time disposing
his troops in such guise that he can keep back the
enemy, if issuing from its lines, it should attempt
to attack his left. To prevent this movement
troops are established on a line parallel with the
white works. A regiment of cavalry and of in-
fantry are placed on the right and in the rear.
" These disposition taken, the corps d'armee at-
tacks in two lines. Two divisions advance en eche-
lons on the right; the commanders of these echelons
having between them the distance necessary to
form obliquely to the left in battle, by a simple
change of direction to the left.

,g While these various movements were taking
place the Emperor, accompanied by a numerous
staff, arrived at the scene of action. Princess
Murat, on horseback, followed the movements of
the staff.

"At the moment of his Majesty's arrival the
first echelon of the corps d'arnzee arrived on the
plateau to the right of a small wood, where it met
with a determined resistance, so that it had to wait
till the echelon to its left had reached the rest of
the high ground running from the little wood to a
given point in the plain.

" Artillery, with a reserve, is established in bat-
tery on the crest so as to play upon the enemy's
works.

" Meantime the reserve division comes up to the
support of a division placed to the right, and the
Various corps united attempt a general effort upon
the enemy's left.

" The remainder of the army only now begins
moving, and advances against the white works as
soon as the left defences are threatened.

" The cavalry supports the right of the corps
d'arnzee, ready to fall upon the enemy's flank should
an opportunity present itself.
" The works are stormed and carried, and the
enemy is pursued by the main body of the army,
the cavalry charge, the rout is complete, and the
enemy retreating by the village of St. Hilaire,
crosses the river Suippes, thus placing that stream
between itself and the victorious army.

f, Just at the close of the manoeuvres the Prince
Imperial arrived on horseback, and accompanied
his august father in visiting the different corps on

the ground.

" This grand manoeuvre, which commenced at
5 a.m., lasted till 10 o'clock.

" All tho troops behaved admirably.

" Prince "William of Baden arrived at Mour-
melon at five o'clock. The Imperial train went to
meet him at Chalons. On alighting he was received
by Prince J. Murat, who accompanied him in an
open carriage to the Emperor's head-quarters."
