Yes, Grant and Lee had one brief encounter after Appomattox, when Grant was President, and I wrote about it in an essay that I titled “Grant and Lee" becomes I’m obviously a creative genius. Here’s the part about their post-Appomattox encounter:
We have so much information on Ulysses S. Grant and Robert E. Lee that we can piece together nearly every aspect of their lives, and often in their own words. Few Americans have affected the lives of so many people while also having such an influence on one another. There are hundreds of books about Grant, Lee, the Civil War, and dozens of combinations of subjects featuring those two great military leaders and their times. What most people don’t know is that Appomattox wasn’t the last time Grant and Lee saw each other.
On May 1, 1869, President Ulysses S. Grant welcomed the president of Washington College, Robert E. Lee, to the White House. Lee had considered inviting President-elect Grant to visit Washington College before Grant was inaugurated, but Lee didn’t want to make a request that his busy former adversary felt obligated to accept. After Grant was inaugurated in March 1869, he learned of Lee’s interest in visiting with him, and the President invited Lee to the White House. Unfortunately, there are no definitive answers to what was said between President Grant and General Lee. They two men only spent about 15 minutes together, and one observer suggested that there was a bit of sadness when the two men saw each other. Perhaps it was because of what they put each other through five years earlier, but perhaps it was the fact that the two former generals were older and in much different places.
What’s remarkable about the short meeting is that Robert E. Lee may have been the only American in history to visit the White House after being stripped of his citizenship. A bill to restore General Lee’s American citizenship was passed by Congress in 1975 — 110 years after the Civil War ended — and President Gerald Ford signed off on the restoration of Lee’s citizenship in a ceremony at Arlington House, the home that Lee lived in before it was occupied by Union soldiers during the Civil War and turned into a National Cemetery.
After just fifteen minutes on May 1, 1869, President Grant and General Lee once again parted ways. We don’t know what they said or how they felt or what they thought as they parted. The two men who had been such a huge part of each other’s lives would never see each other again. Perhaps the most amazing thing is that Grant and Lee could come together at all after chasing each other throughout the country and killing thousands of Americans while trying to destroy each other. It’s a tribute to the two men that they were living in a country still needing time to heal, and they stepped forward — leading the way just like they did while waging war — to model for Americans how to wage peace.
