Well, early on the 12th, General Howard instructed General Sturgis to make forced marches and overtake the Nez Perces. He had but one medical officer and asked for another, and Merrill said they wanted me. I told them they would have to give me a good horse, as mine was wom out, and Merrill said should have one of his. So I was ordered out. Marched from 6:30 A.M. until 9 P.M.. a long and weary ride. It rained all afternoon and my boots and everybody else's got full of water Made a wet and disagreeable camp with but little to eat.
