I got this via email from Alexander. It’s not a lengthy piece but it is moving. I’d suggest bookmarking the link for when you have 15 minutes or so to reflect on the history and remnants of the flags.
The Civil War Trust has partnered with leading Civil War flag conservancies and military museums to present to you this selection of authentic Civil War flags that flew with units that fought at the Battle of Antietam. The flags are presented in rough chronological order – showcasing these remarkable artifacts that were prized by men who carried them into the maelstrom of Antietam.
