2013 will be the 150th year since the battle of Gettysburg. Before the troops got to Gettysburg they tried to cross the Susquehanna River at Wrightsville. The goal was to reach Philadelphia, Harrisburg and other key locations. The residents of Columbia (just a little river town) stopped the advancement by burning the bridge that connected Wrightsville with Columbia. Columbia will be celebrating this event on the actual date of the burning. June 28, 2013. Civil War buffs can come and experience this event before going on to Gettysburg for the celebration there. Plan now.
