Here are historians John Marszalek and Craig Symonds discussing Ulysses S. Grant and Robert E. Lee.
The video’s description reads, “Historians John Marszalek and Craig Symonds looked at the military rivalry between Civil War Generals Ulysses S. Grant and Robert E. Lee. They compared Grant and Lee’s childhoods, their experiences at West Point, their actions during the Mexican-American War, and their battles as commanders of Union and Confederate armies. The New-York Historical Society hosted this discussion.”
Unfortunately, “due to technical difficulties, there was interference throughout the program, and parts of the second half have no video and some audio loss.”
