Hundreds of Civil War re-enactors stage the Battle of Ushers Ferry this weekend in Cedar Rapids. Vicki Hughes, director of the Ushers Ferry Historic Village, says many re-enactors base their performances on real battles from the war between the states. This battle is a conglomeration of several battles, Hughes says, as the cavalry plays a major role in the re-enactment. Both fighting forces will display cavalry drills in various mounted competitions and the Union and Confederate encampments will be open for tours — perfect for kids to learn about the Civil War era direct from the role-players. Hughes says there’ll be a military ball tonight with authentic music from the mid-to-late 1800s.A candlelight tour of the camps is also planned for tonight. Today’s battle is scheduled for 3 P.M. while tomorrow’s (Sunday) battle will begin at 2:30 P.M.
