If you are asking "how did the divided tribes fair on the US side vs the Mexican side" the answer is obvious. I know people who have worked on both sides and the Mexicans treat their independant tribes like shit.

Otherwise, your question makes no sense. Many Californicos (ethnic Spanish) joined the Indians and Anglos and sent the enthnic Mexicans home. The numbers involved in the Bear Flag Republic are tiny: about 5000 Spanish, 700 Mexicans (mostly grunt labor) and perhaps as little as 350 Anglos. The Indians, with a population of 100,000, had the rightful claim to the area which was to become California.
