There are a number of Civil War commemorations happening this year, most notably Gettysburg’s big 150th anniversary. But even if making it out to watch a reenactment of a battle isn’t in the cards, there is still an option to get in on the action. Tonight and tomorrow, more than 30 people will be “live-tweeting” William Quantrill’s 1863 raid on Lawrence, Kansas — one of the bloodiest events in Kansas history that left nearly 200 people dead and much of the town burned. Tweeters have created accounts for figures integral to the battle — townspeople, Union soldiers and proslavery leader William Quantrill — that will be used to recreate the act of terrorism minute-by-minute. Follow the hashtag #QR1863 to be transported to another time and place. I guess you can call it Twitter time travel!
