dSouth branch.

From the above statement it appears that the total number of pontoon bridges built was thirty-eight, and their aggregate length 6,458 feet. I have endeavored to be as brief as possible, but in carrying out your instructions as to detailed descriptions of all the operations of this command I have been compelled to make this report much longer than I could have wished. During the whole time covered by this report I believe the pontoon trains have been promptly on time when ordered, the bridges rapidly and skillfully built, and all other engineering operations of this command faithfully performed. Whatever credit may be awarded for this sis mainly flue to the energy and skill of the officers in immediate charge of the several works and to the zealous and faithful co-operation of the men under their command.

Very respectfully,

I. SPAULDING,

Lieutenant-Colonel, Commanding.

Major J. C. DUANE,

Chief Engineer, Army of the Potomac.
