Nashville, on the third day, we were stopped by the swollen waters of the Duck River, which proved so wide and deep that we had the alternative of bridging it or of waiting for its subsidence. Strange to say, General Buell's army was not provided with any pontoons. The construction of a bridge being decided upon, General R. W. Johnson's brigade of McCook's division was detailed to erect it. The work was mainly performed by the numerous mechanics in the Thirty-second Indiana Regiment, entirely composed of Germans and commanded by Colonel August von Willich.

I made the Colonel's acquaintance on this occasion, and found him a stern and most able and energetic soldier, with astonishingly radical political views for one of his antecedents. The personal relations then formed continued till his death, long after the close of the war.
The bridge construction delayed us ten days on Duck River, and thereby came near entailing disastrous consequences upon the Union cause that might have changed the outcome of the Civil War. As all Buell's advices from Halleck indicated that he (Buell) would meet Grant on the right bank of the Tennessee — that is, with the river be tween them and the enemy — he felt no apprehension as to Grant's safety before his junction with him.

This transposition, together with the knowledge of Buell's detention at Columbia, had determined A. S. Johnston and Beauregard to strike a blow at Grant before he was reinforced by Buell. The official records make it plain that they would thus have
