Douglas's Texas Battery (also known as the Good-Douglas Texas Battery or Dallas Light Artillery Battery) was an artillery battery that served in the Confederate States Army during the American Civil War. In June 1861, the unit was formed by combining one group of men from Dallas with a second group from Tyler and placing them under the command of John Jay Good. The battery fought at Pea Ridge in March 1862 and soon afterward transferred to the east side of the Mississippi River. James Postell Douglas replaced Good as commander and led the battery at Richmond, Stones River, Chickamauga, Chattanooga, the Atlanta Campaign, Franklin, and Nashville. After operations around Mobile, Alabama, Confederate units in the region surrendered and the survivors of the battery were paroled on 12 May 1865. It was the only Texas field artillery unit that served east of the Mississippi.
