Petersburg National Battlefield
Petersburg National Battlefield is most widely known as the site of the longest siege in American warfare. With General Robert E. Lee's Confederate forces stretched between Richmond and Petersburg, Union General Ulysses S. Grant cut off all supply lines and forced General Lee's hand. By early February 1865, General Lee had 60,000 troops in contrast to General Grant's 110,000 men. After 10 months of battle, General Lee evacuated Petersburg on April 2.
