The Siege of Petersburg: The Longest Military Event of the Civil War
Nine and a half months, 70,000 casualties, the suffering of civilians, U. S. Colored Troops fighting for freedom, and the decline of Gen. Robert E. Lee's Army of Northern Virginia all describe the Siege of Petersburg. Gen. Ulysses S. Grant cut off all of Petersburg's supply lines, ensuring the fall of Richmond on April 3, 1865. Six days later, Gen. Lee surrendered.
