"In May 1863, after months of hard and bitter combat, Union troops under the command of Major General Ulysses S. Grant at long last successfully cross the Mississippi River. They force the remnants of Confederate Lieutenant General John C. Pemberton's army to retreat to Vicksburg, burning the bridges over the Big Black River in its path. But after sustaining heavy casualties in two failed assaults against the rebels, Union soldiers are losing confidence and morale is low. Grant reluctantly decides to lay siege to the city, trapping soldiers and civilians alike inside an iron ring of Federal entrenchments.
