Frontier service during the rebellion

The first battle of Bull Run had been fought. The government had become satisfied that the slaveholder's rebellion was not to be put down with seventy-five thousand men. The Union people of the United States now fully realized that the rebels were to use every effort on their part towards the establishment of the Confederacy, and the men of the north, on their part, were ready to 'mutually pledge to each other our lives, our fortunes, and our sacred honor' to preserve the government as their fathers before them had pledged themselves to establish it. The loyal States were ready to respond to any demand made upon them by the government, and there were none more anxious to do their duty to the old flag than the Union men of California.
