Performers fire blank rounds at opposing forces during a Civil War reenactment. See battles at this year’s reenactment at 11 a.m. and 3 p.m. Saturday and Sunday and 11 a.m. Monday at the Clatsop County Fairgrounds.

ASTORIA — One of the Northwest’s largest Civil War reenactments is returning to the Clatsop County Fairgrounds over Labor Day weekend.

The event draws hundreds of reenactors each year from around the Northwest for live battles and demonstrations of artillery, cavalry, fashion and medicine from the 1860s.

Camps are open to the public between 9 a.m. and 4 p.m. Saturday and Sunday and from 9 a.m. to 2 p.m. Monday. Battles are scheduled for Saturday and Sunday at 11 a.m. and 3 p.m., and Monday at 11 a.m. There will also be a Civil War-era church service at 9:30 a.m. Sunday.

Fort Stevens State Park, which is home to a fort built during the Civil War to guard the Columbia River from potential Confederate and British attacks, hosted the annual reenactment for decades before it moved to the fairgrounds.

Admission is $15 for adults, free for kids 12 and under. For more about the event, visit www.nwcwc.net.
