On this day 150 years ago, Union forces were busy closing the Mississippi River to Confederate traffic immediately below Vicksburg. The river above Vicksburg had been closed for some time by the Union Western Gunboat Squadron. In just a few hours, Vicksburg would be cut off from the Confederate Trans-Mississippi and from resupply and reinforcement by river, north and south.
