The total acreage burned in Monday's grass and brush fire that began on the Camp Bowie Training Facility has been recalculated at 901 acres, Brownwood Fire Marshal Buddy Preston said Wednesday.

Officials said earlier that 700 acres had burned.

Of the 901 acres, 603 were on Camp Bowie and 298 were on private property, Preston said.

Brownwood Fire Department officials also said approximately 175 firefighters with about 50 pieces of equipment responded to the blaze, which sent smoke billowing high into the sky south of Brownwood around noon Monday.

The smoke, which was visible for miles around, dumped soot across an area northeast of the fire. The smoke could be detected in many areas of the county Monday night and early Tuesday morning, even though most of the firefighters left the scene by sunset on Monday when the blaze was extinguished.

A Texas National Guard commander said the fire was ignited by a ricocheting tracer round on a machine gun firing range.

Preston said 18 volunteer fire departments and numerous agencies from Brown and other counties responded to the fire. The Texas Forest Service provided helicopters and other equipment.

A burn ban is in effect following action Monday morning by the Brown County Commissioners Court.

Preston said conditions remain ripe for more grass fires, perhaps even some as dangerous as the one Monday. Dry conditions, low humidity, high temperatures and strong winds are key factors in the spread of grass fires, especially when growth is sufficient in the area to serve as fuel.
