After 155 years, there are still living witnesses to the Battle of Gettysburg and other Civil War battles, or events in U.S. history: trees. There are over 6,000 acres of land in the Gettysburg National Military Park, and rangers have documented at least a dozen "witness trees" that were alive during the battle. There are also similar trees at Antietam, and at other locations. A recent article by CBS News discusses these old historic trees: https://www.cbsnews.com/news/rooted-in-history-witness-trees-gettysburg-national-military-park/ . Trees that may have been witness trees are very powerful living links that we can view and touch, to events in our history.
