Bermuda Hundred refers to a strategic location along the James River in Virginia during the American Civil War. The Adams Express Office at this site served as a military headquarters for the Union's Army of the James. This army was part of the Department of Virginia and played a significant role in several key battles, including the Bermuda Hundred Campaign and the Siege of Petersburg. The location's historical significance lies in its strategic position, which facilitated supply lines and military operations during the latter stages of the war. Today, remnants of this historic site are preserved as part of the cultural heritage in Chesterfield County, Virginia.
