DUCKPORT CANAL.
A similar effort to turn Vicksburg’s left flank was essayed by cutting a canal at Duckport, between Milliken’s Bend and Vicksburg. By this avenue it was hoped vessels might leave the Mississippi above Vicksburg, pass through a series of circuitous bayous and emerge again on the Mississippi 20 miles below the city. The route was laboriously opened for navigation and one small steamer safely passed to the river below. Then the level of the river fell and blocked the Duckport attempt.
