The bridges were soon built of such material as could be found near by, and so substantial were they that not a single mishap occurred in crossing all the army with artillery, cavalry and wagon trains, except the loss of one siege gun (a thirty-two pounder).

This, if my memory serves me correctly, broke through the only pontoon bridge we had in all our march across the peninsula.

These bridges were all built by McClernand's command, under the supervision of Lieutenant Hains of the Engineer Corps.
I returned to Milliken's Bend on the 18th or 19th, and on the 20th issued the following final order for the movement of troops: HEADQUARTERS DEPARTMENT OF THE TENNESSEE, MILLIKEN'S BEND, LOUISIANA, April 20, 1863.
