Just to echo Bruce Nichols. Otterville and the Pacific Railroad's Lamine (or LaMine) River Bridge are names used interchangeably. The federals built impressive earthworks to guard the bridge which were garrisoned throughout the war. At the beginning of northern occupation, there was the "affair at Otterville" in which State Guardsmen and federal troops confronted each other, negotiated, and all decided to go home. The bridge was burned in 1863 during Gen. Shelby's raid and again in 1864 during Gen. Price's raid by Todd and others. There is dispute about a third burning, depending on point of view. In spite of all the effort and activity, no major engagements were fought there. Old timers tell me that the Yankees left the works by train for Sedalia in both '63 and '64.
