City of Mexico taken.
--The Galveston News of the 2d inst., says:‘ An official letter from the French Consul at Matamoras states that the city of Mexico had been captured by the French troops. Tampico was occupied by 3,000 French and some reactionary troops on the 23d of December, and there were, at the time of writing 8,000 troops in that city, Matamoras may at any moment be occupied by the French, and will certainly be soon. The French army numbers over 40,000 men--four times the number necessary for the taking of the whole of Mexico.
’ The News thus alluded to this interesting information:
‘ We look upon this as very important news.--The conquest of Mexico by the French; or which is the same thing, the absolute military control over that country by Napoleon, places French power in contiguity with the Confederate States on the South, as English power is in contiguity with Lincoln's Government on the North. It is worthy of note that white France has been steadily, and noiselessly establishing her power in Mexico by large fleets and armies, Great Britain has been equally indefatigable in sending some forty or fifty thousand troops and immense army supplies into Canada. These military operations in Canada and in Mexico have been going on simultaneously, and, apparently, with a like determination by both Governments to avoid attracting much observation. Under such circumstances it is difficult to believe that these observations are being carried on without a mutual understanding between those Governments and a predetermined purpose to be soon.
