I must here state that Klingensmith was not in Cedar City that Sunday night. Haight said he had sent Klingensmith and others over towards Pinto, and around there, to stir up the Indians and force them to attack the emigrants.
On my way from Cedar City to my home at Harmony, I came up with a large band of Indians under Moquetas and Big Bill, two Cedar City Chiefs ; they were in their war paint, and fully equipped for battle. They halted when I came up and said they had had a big talk with Haight, Higby and Klingensmith, and had got orders from them to follow up the emigrants and kill them all, and take their property as the spoil of their enemies.
These Indians wanted me to go with them and command their forces. I told them that I could not go with them that evening, that I had orders from Haight, the big Captain, to send other Indians on the war-path to help them kill the emigrants, and that I must attend to that first; that I wanted them to go on near where the emigrants were and camp until the other Indians joined them ; that I would meet them the next day and lead them.
This satisfied them, but they wanted me to send my little Indian boy, Clem, with them. After some time I consented to let Clem go with them, and I returned home.
