and the infantry to camp and watch for the enemy at a suitable place in the former direction, proceeded to the coast with his cavalry. There he found the transports in sight and the wind favorable. Defences were planned at once; and on the 27th, leaving an engineer, supported by a guard under Munroe, to superintend the construction of them, the General returned to the army, then some ten miles from Matamoros. The next morning all advanced, and soon came to rough defiles. On each side bristled What a soldier described as an irregular, impenetrable mass of "scraggly, scrubby, crooked, infernally illegitimate and sin-begotten bushy trees loaded with millions of thornpins" — that is to say, chaparral. Passing this and a few cabins in the midst of corn, cotton and pomegranates, the troops found themselves at the end of their march, Rio Bravo, the "Bold river of the North," brown with mud, rolled swift and boiling at their feet; and in plain View about half a mile distant — black with crowded house-tops, gay with flags, and noisy with bugles and barking dogs — lay Matamoros.
