MANASSAS, Va. (AP) — Re-enactors are wary of triple-digit heat forecasts in Virginia as they prepare to commemorate the 150th anniversary of the Battle of Bull this weekend.

When the North and South clashed in July 1861 in the Civil War's first major battle, temperatures were in the 80s. Re-enactments planned for Saturday and Sunday will occur on days when the temperature is expected to rise above 100.

Re-enactors say they might take it a little easier on the battlefield, but will not sacrifice authenticity to beat the heat.

The National Park Service says it will not hold any of its outdoor programs for the anniversary from 2 p.m. to 6 p.m. Friday because of the heat. The re-enactment and other events are organized privately or through local governments.
