Battle - Fort Pulaski - Chatham County, Georgia

Fort Pulaski
Fort Pulaski

Fort Pulaski, built between 1829 and 1847, was placed near the mouth of the Savannah River to block upriver access to the city. Brick and masonry fortifications such as Pulaski, called "third system" forts, were considered invincible, but the new technology of rifled artillery would soon change that. To shut down blockade running traffic from coastal Georgia and South Carolina, the Union army and navy mounted an expedition in November, 1861 to occupy the land area surrounding Savannah. Tybee Island, opposi…READ MORE

Confederate Maj. Gen. "Stonewall" Jackson hoped to cut off the Union retreat from Manassas the day after the Confederate victory at the second battle fought there. Jackson's wing of Lee's army made a wide, flanking march, screened by Maj. Gen. J.E.B. Stuart's cavalry, north and then east, to take the strategically important village of Germantown. There, Maj. Gen. John Pope's only two retreat routes to Washington - the Warrenton Pike and the Little River Turnpike - converged. On September 1st, beyond Chanti…READ MORE

After his success at Second Manassas, Gen. Robert E. Lee led the Army of Northern Virginia north across the Potomac River on an invasion of Maryland in September of 1862.

The bold plan was jeopardized on September 13th when a mislaid copy of Lee's orders revealing the Confederates' plans was given to Union commander Maj. Gen. George B. M…READ MORE

Vicksburg

In mid-May, 1863, after six months of unsuccessful attempts, Maj. Gen. Ulysses S. Grant's Army of the Tennessee finally converged on Vicksburg, defended by a Confederate army under Lt. Gen. John C. Pemberton. Capture of the Mississippi River town was critical to Union control of the strategic river. Vicksburg was located on a high river bluff defended with artillery, and Pemberton's men had constructed a series of fortifications in an 8-mile arc surrounding the city on the landward side.

Following the Battle of the Wilderness, Lieut. Gen. Ulysses S. Grant marched the Union army south with the hope of capturing Spotsylvania Court House and preventing Robert E.

Following the stalemate at Spotsylvania Court House, Grant was determined to continue his offensive against Lee's Army of Northern Virginia. After a failed attempt to bait Lee out of his earthworks, he found the Confederates entrenched on the south side of the North Anna River, where Lee's "inverted V" defenses forced Grant to divide his army into three parts in order to attack.

After two days of inconclusive fighting along Totopotomoy Creek northeast of Richmond, Lt. Gen. Ulysses S. Grant and Gen. Robert E. Lee turned their sights on the crossroads of Cold Harbor. Roads emanating through this critical junction led to Richmond as well as supply and reinforcement sources for the Union army. On May 31, 1864, Maj. Gen.

As the Overland Campaign concluded, the strategic goals of Lieut. Gen. Ulysses S. Grant shifted from the defeat of Robert E. Lee's army in the field to eliminating the supply and communication routes to the Confederate capital at Richmond. The city of Petersburg, 24 miles south of Richmond, was the junction point of five railroads that supplied the entire upper James River region. Grant knew Petersburg was the key to the capture of Richmond and that Lee would be forced to defend it. Marching south from Co…READ MORE

Two weeks after Union forces arrived to invest the Confederate defenders of Petersburg, the battle lines of both sides had settled into a stalemate. Since Cold Harbor, Lieut. Gen. Ulysses S. Grant was reluctant to mount a frontal attack against well-entrenched Confederates. By late June, Grant's lines covered most of the eastern approaches to Petersburg, but neither side seemed ready to risk an offensive move. Part of the Union line was held by Maj. Gen. Ambrose E. Burnside's Ninth Corps. Some of Burnside'…READ MORE

By February 1865, the stalemate around Petersburg had entered its eighth month. Lieut. Gen. Ulysses S. Grant began to stretch the Union battle lines to the west in an attempt to get Gen. Robert E.

By March of 1865, Lieut. Gen. Ulysses S. Grant's grip on the Confederate lines around Petersburg was having its desired effect. Outnumbered and weakened by disease, desertion and shortage of food and supplies, Gen. Robert E. Lee had few options. After careful study of the Union troops in his sector of the line, Maj. Gen. John B. Gordon suggested to Lee the possibility of a successful offensive strike against Grant. In front of Gordon's men, Union-held Fort Stedman seemed the best target for a Confederate a…READ MORE
