In October, 1852, events occurred in the Mexican State of Sonora, which the Californians could not but regard with much interest. Count de Raousset-Boulbon, a French adventurer, was the prime actor, in a brief but stirring drama, in that quarter. He had come to California in search of fortune. Being unsuccessful, he went to Mexico. At the period of his arrival there the Province of Sonora was devastated by the Alpaca Indians, who committed all sorts of depredations with impunity. Count de Raousset-Boulbon presented himself to the Mexican Government, and offered to deliver Sonora from the red-skins with which it was infested. The Mexican Government was ready to fall upon the neck of M. de Raousset-Boulbon. "I am a Frenchman. I know the country. I understand war. I will answer for every thing," said the Count. "Good," said the government, "we will place an army of ten thousand men at your disposal." "Thank you," said M. de Raousset-Boulbon, "keep your army; it would only get in my way. Give me some muskets, and two hundred thousand francs, and leave the rest to me." He received the required sum, returned to Sonora, organized a corps of Frenchmen, resolute men like himself, and proceeded to hunt down the Indians. The merchants of the country, delighted with the successes obtained by their defender against a set of rascals who had so long been masters of their provinces, sent subsidies to M. de Raousset-Boulbon, put themselves under his protection, and assured him that neither he nor his troops should ever want for any thing if he would only continue the war. The Count closed with the offer. But the popularity of the young general, and the success of his little army, alarmed the Mexican Government. They issued an order requiring him to quit the country with his forces. Count de Raousset-Boulbon replied, that the merchants and land-owners of the country having placed Sonora under his immediate protection, he felt it due to his honor not to abandon them, and consequently he distinctly refused to obey the order. The Mexican Government then sent a frigate to blockade the principal port of Sonora. Count de Raousset-Boulbon took the frigate. The government sent Gen. Blanco, at the head of an army, against the French commander. A battle was fought, and after a short but fierce struggle, superior numbers triumphed, and the French were defeated. A treaty was then negotiated, by the terms of which, Count Boulbon agreed to quit Sonora, in consideration of receiving a large sum of money.
