Chief joseph had meet lewis and clark on their
way he let me go pass and became friends with them as well. But he they all had a journey they wanted to do Joseph didn't want to have war with indians so he did the best he could to prevent that from happening and that's was the something going with lewis and clark they didn't wanted war with anyone at all so did jefferson. Chief joseph really didn't have many soldiers to fight if they even did go into war with the indians so really that's why he didn't want to do that. The first white men who came to his country was lewis and clark. In momaday they were on a journey just like lewis and clark they both had a hard time on their new journey it wasn't going to be easy for them but they both had some help on the way.
How joseph wanted peace between two groups and lewis and clark made a trade to make an agreement with them and why he didn't wanted to go into war was because he didn't really have many men to go into war with that's why joseph wanted to make peace with the indians. Same with lewis and clark they really didn't want to either. They had to have food and other stuff to survive off of as well. Nez perce wish to live at peace so with no war or fight with anyone or anybody.
