A House Divided, our Civil War blog, has a full rundown on all the goings on in Manassas and will be liveblogging there on Saturday, but here are the highlights for anyone interested in picking up a musket.

•The festivities kick off Thursday with a commemorative ceremony at 9:15 a.m., which will feature comments by Virginia Gov. Bob McDonnell (R) and a host other activities.

•The reenactment of the battle takes place Saturday, beginning at 9:30 a.m. The battle will feature more than 8,700 reenactors. And if you want to know how to play a dead soldier, here’s a primer.

There’s plenty of other stuff to see as well. Manassas National Battlefield Park kicked off this week by unveiling a new exhibit that features a belt buckle worn by Confederate Gen. Stonewall Jackson and a shotgun carried by southern partisan Col.John Singleton Mosby.
