Helena, Saturday, Sept. 19. Still very chilly, the wind being raw from the river. Slept comfortable last night. The train which we were to escort moved this morning with the cavalry, so the object of our expedition is abandoned and we are lying here waiting orders. Mail arrived at tatoo. I received one enclosed in E. W. E.’s but none from home. It has been four weeks since the last I received from home. I am very uneasy. I am afraid all is not well.
