Read the final two paragraphs from "Money to Us Is of No Value."

You have talked to us about concessions. It appears strange that you should expect any from us, who have only been defending our just rights against your invasions. We want peace. Restore to us our country, and we shall be enemies no longer.

We desire you to consider, brothers, that our only demand is the peaceable possession of a small part of our once great country. Look back and review the lands from whence we have been driven to this spot. We can retreat no farther, because the country behind hardly affords food for its present inhabitants, and we have therefore resolved to leave our bones in this small space to which we are now confined.
