Saturday, April 19.— Rained violently; starting postponed. Order modified to marching by easy stages to Flat Top Mountain, there to choose strong position. General Fremont speaks of our forces as his right wing; the left must be up towards Cheat Mountain. We are now at the pivot; to proceed slowly until the left wheels so as to face southwardly with us. Rained all day; couldn’t move. At evening looked slighteously like clearing off.
