The White Scalper by Gustave Aimard

The news told White Scalper by the scout was true; Tranquil and his comrades, after turning the Mexican lines with that craft characteristic of the Indians, had effected their junction with the Texan army; that is to say, with the vanguard, commanded by the Jaguar. Unfortunately, they only found John Davis, who told them that the Jaguar had gone to make an important communication to General Houston.

If the American had spoken to Tranquil about his daughter, and given him news of her, he would have been forced to reveal the bargain proposed by the Chief of the Pirates, and he did not feel justified in divulging a secret of that importance which was not his own. The Canadian consequently remained ignorant of what was going on, and was far from suspecting that his daughter was so near him; besides, the moment was a bad one for questioning; the march had begun again; and during a retreat the officers who command the rearguard have something else to do than talk.
