From the Rio Grande
--
An Abolition Raid. Brownsville and
Corpus Christi papers contain accounts of a boldly-attempted and timely-frustrated abolition raid on the
Rio Grande, in
Zapata county.
It appears that about forty of the citizens (half-breeds) organized, armed and marched upon Carizo, the county seat of
Zapata county, with the object of preventing the civil officers taking the oath of office prescribed by the
Confederate States Constitution.
After starting they were joined by a band of thirty more, all well armed and organized.
This quite formidable force, after holding a council and pronouncing in favor of the United States Government, was proceeding upon Carizo when intelligence of the insurrection reached
Col. Ford, at
Laredo.
Under orders from
Col. Ford,
Captain Nolan, with twenty-three men, advanced upon and attacked the insurgents — then numbering eighty men --at a point some eighteen miles from Carizo.
and completely routed them, killing three and wounding six.
Capt. Nolan's command sustained no loss.
The Brownsville Flag seems to think that Cortina is at the bottom of this move, and says he has subsequently been seen on the
American side of the river within twenty miles of
Brownsville, soliciting aid for another attack.
This Cortena has become a nuisance upon the
Texas frontier, that should be immediately abated, cost what it may.
It is reported that another revolution has been inaugurated in
Mexico, with
Mejia at its head, who is said to have met and defeated Dorado, and to be in possession of many strongholds throughout the country.--
