What evidence does the speaker present that his people are hurting?

I’ve answered this before and this is the excerpt for your question:

"My people, some of them, have run away to the hills, and have no blankets, no food. No one knows where they are-perhaps freezing to death. I want to have time to look for my children, and see how many of them I can find."

The evidence that the speaker presents that his people are hurting is " They are missing and lacking warm clothes and food."
