CAPITAL.

" Soldierx,—Two months have not yet passed since,
General Rivßra marched from the capital, with part of
the forces which defended it ; yet,. within 50 days he
has obtained five victories over the enemy, gaining, as
the result, the occupation of the coast of the Uruguay.
" General Rivers commenced his campaign without
one horse—to-day he is at the head of a strong army
and well mounted. He has just given a new triumph to
the Republic by his capture of Mercedes, of 500 pri-
soners with all their arms ; "Mootoro and Morancelli ure
arnonr, the dead.
The Government has received the official account
of this victory. I congratulate you on its great ini-
porttince.

GENERAL RIVERA'S DISPATCFI.
" Mercedes, June 16, 184 G.
"From San Salvador I informed the Goverment of
the complete rout of the enemy's cavalry, commanded
by Colonels Montoro and Flores. The latter was pur-
sued by Commander Sosa into the woods of Agraciada.
Commander Sosa joined me on the night of the 12th,
and I Imil•news shortly after that Montoro, having taken
refuge in this place, had gathered together about 300 of
the dispersed cavalry ; that he reckoned on a eluef
named Granada, who held a division south of the Rio
Negro, in front of Mercedes ; and that, trusting to this
aid and the strength of this place, defended by above 400
infantry and seven pieces of artillery, he had determined
to make a stand, come what would.
" I invantly gave orders to march, and to cross the
river San Salvador, which was much swollen. This
was effected at dawn of the 13th. and I then forced my
march. At live, P.-M., I was at Saree del Biscoeho ; not-
withstanding a torrent of rain which fell, we passed the
Maulas and the Daca all but swimming ; for severs
leagues we never halted, it being of the utmost conse-
quence that we should come upon the enemy by break
of day, and unawares.

" I advanced in person to reconnoitre his position,
and ordered my infantry forward for the attack, Colonel
Baez to lead the battalion of Vascos against a group of
about 300, who were firing from the town, and Colonel
Flores, with the artillery, to attack the azoteas of the
Plaza, upon which were stationed large numbers of the
enemy ; the battalion of Colonel Lavandera formed our
left ; our cavalry surrounded the town. Within ten
minutes after Colonel Baez opened the attack the enemy
yielded before our bayonets in the principal streets, but
termed again in great strength in the Puerto ; there he
held but t'or to o hours, making a vigorous defence, but
at the end of that time was completely overcome, with
the loss of his principal chiefs, his artillery, and every-
thing defensive he possessed. On our park the only
damage sustained has been an officer of the Vascos and
seven soldiers slightly wounded.
" At half.past eight there were in our power 500 pri-
soners, a colonel of infantry, and 40 subaltern officers..
Montoro himself was among the killed, and Morancelli,
and various other chiefs, 1,500 stand of arms, five pieces
of artillery, abundance of munitions, and 2,000 horses in
good condition, have fallen into our hands ; and,
moreover, we have liberated Mercedes, after her three
years' sufferings under the yoke of a detestable enemy.

Ignacio'Oribe, it is supposed, was at Maharaja, and
Servando Gomez at Arroyo Valdez. At Mercedes it is
thought the latter has not a force altogether of 700
men.

Rivera says, in ti private letter to Snares, the Pre-
sident, bearing the same date as his dispatch :
" The resources are immense of which the Govern-
ment can now dispose. We remain masters of a vast
district, full of cattle, and of people who will in a short
time render important services in the operations of the
army. Trade may at once commence between this and
tie capital, and will soon drive away those distresses
which your heroic people have for three years sufKlred.
" The troops are hearty7and desirous to be aga:m in
action to acquire fresh glory for their country.
" Colonel Baez bears to the Government every in-
formation in my power for their guidance, and, above•
all, what can be done in supplying them with resources
at once. I beg you will congratulate in my name their
Excellencies the Intervening Ministers, and the Ad-
mirals of England and France, for the part and co-
operation which they have taken in all the successes of
the Republic."
An expedition sailed out of Colonia, under command
of Colonel Solsona, on the 19th, to attempt a surprise on
the town of Colla, 13 leagues distant. It has been
crowned with complete success ; the column returning
to garrison on the 24th full of the spoils of war, and
bearing with them, as the principal trophy, the go-
vernor of the town. The place was defended by 240
men and two pieces of artillery.
Accounts have been received from Salta of a very fa-
vourable nature. Mundell had arrived there, and was
organising troops ; and Garribaldi was strong in
cavalry.
