The Mariposa Battalion, was assigned by Governor McDougall to the duty of keeping in subjection the Indian tribes on the east side of the San Joaquin and Tulare valleys, from the Tuolumne river to the Te-hon Pass. As soon as the battalion was organized, Major Savage began his preparations for an expedition. There was but little delay in fitting out. Scouting parties were sent out, but with no other effect than to cause a general retreat of the Indians to the mountains, and a cessation of hostilities, except the annoyances from the small bands of thieving marauders. No Indians were overtaken by those detachments, though they were often seen provokingly near. When about to start on a more extended expedition to the mountains, Major Savage received an order from the Governor to suspend hostile operations until he should receive further instructions. We learned at about the same time through the newspapers, as well as from the Governor’s messenger, that the United States Commissioners had arrived in San Francisco. Their arrival had for some time been expected. Up to this period the Indian affairs of California had not been officially administered upon. Public officers had not before been appointed to look after the vast landed estates of the aboriginal proprietors of this territory, and to provide for their heirs. After some delay, the commissioners arrived at our camp, which was located about fifteen miles below Mariposa village. Here the grazing was most excellent, and for that reason they temporarily established their head-quarters. These officials were Colonels Barbour and McKee, and Dr. Woozencroft. They were accompanied by Col. Neely Johnson, the Governor’s aid, and by a small detachment of regulars. The commissioners at once proceeded to make a thorough investigation into the cause of the war, and of the condition of affairs generally. Having secured the services of some of the Mission Indians, these were sent out with instructions to notify all the tribes that the commissioners had been directed by the President to make peace between them and the white settlers; and that if they would come in, they should be assured protection. The so-called Mission Indians were members of different tribes who had been instructed in the belief of the Catholic Church, at the old Spanish Missions. These Indians had not generally taken part in the war against the white settlers, although some of them, with the hostiles, were the most treacherous of their race, having acquired the vices and none of the virtues of their white instructors.
