Ho starled from his Camp, on the 28th, with his whole force, to reconnoiire, and, if possible, to open communication with Gon. Taylnr. lic had procceded about midway batween Pjint abel and lbo Camp, when nn overwhetming force of Mexicana approached very sud lenly. A portion of his troops were raw rccruiis.

This force is supposed to be a iportion of that whicli we heard, nt last accOK-iÃ¯ts, crossed the Rio Grande; ome "20 or 25 miles above Matamoros, nnd whioh is estimated at 2,000 men. It is believed thnt thoy had taken a circuiious route on the pnstern side of Gen. Taylor's caiuj. The post is very strongly defended. - lio thinks with 300 men to defend the posi, it can be made good ogainst 3,000. There are now about 8,003 Mexicans on the American side of the Rio Grande onc-Iialf mil-e Lelow Gen. Taylor's Camp. The greaiest apjirchension is, I13' actual storming of the works.
