This program provides students an orientation to the battlefield through an interactive map activity and a tour of Battery Five, where the initial assault on Petersburg occurred.  Students practice their map skills by using a canvas map to view the position of the trench lines around Petersburg and to identify the battle objectives of the Union army.


At the end of this program, students will provide two reasons the Confederates constructed a fortification such as the Dimmock Line around most of the city.

At the end of this program, students will describe two difficulties Baldy Smith may have had during the Union army attack on Battery #5.


As it had been before the Civil War, Petersburg, Virginia was an important transportation center and a critical link between Richmond, (the Confederate capital) and the rest of the South. Through the city of Petersburg came most of the supplies that Richmond needed in order to function.

When the smoke had settled from the Union's failed attempt to take Richmond in 1862, Confederate authorities realized the vulnerability of this supply center. In response, a ten mile-long wall, fortified with numerous gun batteries, was constructed around the city by slave and freed black labor. For the next two years Petersburg was relatively quiet and untouched by the war, with the wall becoming more a place for children to play rather than for soldiers to defend.

In May 1864, Union forces arrived east of Richmond to sever the rail connection into the Confederate capital city. This campaign included several actions against Petersburg but it was not until June 15 that the Union forces arrived at the city's wall with its capture in mind. The battle that night had come after six weeks of heavy fighting between the armies of General Ulysses S. Grant (USA) and General Robert E. Lee (CSA) that had started near Fredericksburg, Virginia and ended just outside of Richmond. After the Battle of Cold Harbor, Grant, realizing that he could not get Richmond by direct assault, had turned to Petersburg knowing that if it fell, Lee would have to abandon Richmond.

Union forces led by General William "Baldy" Smith (USA) did breach the wall on June 15th, but failed to exploit their success. This decision would ultimately lead to the nearly ten month-long siege that turned the landscape around Petersburg into one of trenches and dirt and added another 70,000 men to the casualty lists of the war.

Park Connections

Nine and a half months, 70,000 casualties, the suffering of civilians, thousands of U. S. Colored Troops fighting for the freedom of their race, and the decline of Gen. Robert E. Lee's Army of No. Virginia all describes the Siege of Petersburg. It was here Gen. Ulysses S. Grant cut off all of Petersburg's supply lines ensuring the fall of Richmond on April 3, 1865. Six days later, Lee surrendered.
