In November 1916, Maj. Benjamin Foulois of the Aviation Section of the U.S. Army's Signal Corps chose a tract of land approximately three-fourths of a mile to the southeast of this spot to serve as a flying field for the Army Aviation Corps. In 1917, the site was named Camp Kelly and later Kelly Field in honor of Lt. George E.M. Kelly, who in 1911 had become the first American aviator to lose his life while piloting a military aircraft. Activities at the camp included both flight training and aircraft maintenance. In September 1917, Kelly Field's training activities moved north to this area, called "Kelly No. 2" to distinguish it from the original field.

The new flight line, extending 125 yards east and 2400 yards west of this site, consisted of numerous hangars, warehouses, barracks, repair shops, classrooms, and maintenance buildings. "Kelly No. 2" retained its training function from 1917 through 1942. Its Air Corps Advanced Flying School produced many prominent American aviators, including Charles Lindbergh and Claire Chennault. In 1955, the advent of new and larger aircraft prompted the extension of the existing runway, this necessitating the demolition of the old "Kelly No. 2" flight line.

The Federal Government has operated a coastal installation at Point Isabel since 1852. This structure is the third permanent building erected here, one of a line of nine stations established along the Gulf of Mexico from Florida to the Texas-Mexico border. Originally consisting of a main floor, attic, and lookout tower, all elevated off the ground on wood and concrete pilings, the structure served as barracks and headquarters for the U.S. Coast Guard unit that patrolled the coastline and conducted sea rescues.

As the granddaughter of Lorenzo de Zavala (1789-1836), first vice-president of the Republic of Texas, young Adina de Zavala was exposed to vivid accounts of Texas' Revolutionary and Republican past. She became a guiding force in the preservation of many of Texas' most revered historic structures and sites, including the Alamo, Mission San Francisco de Los Tejas in East Texas, and San Antonio's Spanish Governor's Palace. The "De Zavala Daughters," a women's group formed by Miss Adina in 1889, erected Texas' first historical markers and helped preserve San Antonio's Spanish missions.

Her firm belief, later verified, was that remnants of Mission San Antonio de Valero, known in 1836 as the Alamo's long barracks, lay underneath the wooden exterior of buildings adjacent to the Alamo church. By 1893, as president of the De Zavala chapter of the Daughters of the Republic of Texas (DRT), Miss Adina had secured the adjacent property owner's commitment to give the chapter first purchase option. In 1908, upon hearing that the 2-story long barracks were about to be razed, Miss Adina barricaded herself inside the buildings for three days and nights in an effort that ultimately prevented their destruction.

Prior to the United States entry into World War II, the U.S. Government contracted with a number of civilian flying schools to assist in training military pilots for the Army Air Corps. In December 1940 the Air Activities of Texas, Corsicana Field, was authorized to provide primary flight training, the second phase of a three-level process. Construction of the facility on a 400-acre tract of land began here in February 1941, and employed more than 250 laborers. In addition to a landing strip, they built hangars, barracks, offices, maintenance buildings, and a mess hall/kitchen. In March, 51 cadets arrived to complete 10 weeks of intense training. By 1943, each class contained more than 300 cadets. By 1944 8,480 cadets received flight instruction in 37 training classes. The flight school employed more than 550 civilians by January 1944, and provided a significant impact on the local economy.

As the war drew to a close, the need for the flight school became unnecessary, and it closed. Post-war use of the property began in 1946 with the opening of Navarro Junior College, which occupied the site until 1951. The City of Corsicana purchased the site in 1963 for a municipal airport.

Mission San Antonio de Valero, established nearby in 1718, was relocated here in 1724. By 1762, the Mission Plaza was enclosed by thick stone and adobe walls. The 11 x 14-foot main gateway was located at this site along the south wall. In 1803 Spanish cavalry from San Carlos de Parras del Alamo, Mexico, occupied the secularized mission and built one-story (low) barracks inside the south wall on each side of the main gateway. The Alamo, as the complex came to be known, was occupied in 1835 by Mexican soldiers led by Gen. Cos. They fortified the main gateway with artillery pieces and a defensive lunette, a semi-circular enclosure with deep trenches. In December 1835, Texas patriots captured the Alamo, but by Feb. 23, 1836, were under siege by an armed force led by Gen. Santa Anna. Couriers departed the Alamo through the main gateway during the siege. On March 6 Mexican troops breached the main gateway and retook the Alamo. After the assault, some Mexican military observers and local residents stated that Col. James Bowie and others died in the low barracks. The low barracks and main gateway were leveled in 1871, melding Valero Plaza on the south with the Alamo's plaza to create an open space.

Site of main entrance to Camp Barkeley, one of the nation's largest military camps of World War II. At peak, 60,000 men were in training here. Named for Private David B. Barkeley of the 89th Division, who died on a secret scouting expedition behind German lines during the Meuse-Argonne Battle of World War I. Among famous units trained here were the 45th and 90th Infantry Divisions and the 11th and 12th Armored. A medical replacement training center, the largest in the country, was also established here, with 15 battalions. In May, 1942, the Medical Administrative Corps Officer Candidate School was activated and graduated about 12,500 candidates. Camp Barkeley eventually grew to be a complete city unit twice the size of Abilene of the 1940s. It had a 2,300-bed hospital, 2 cold storage plants, a bakery, 4 theaters, 2 service clubs for enlisted men, 15 chapels, and 35 post exchange buildings. The military personnel were housed in hutments, except for some 4,000 in barracks. Part of the post was also a German prisoner-of-war camp. Once some of the prisoners escaped, to the alarm of Abilene citizens, and others attempted to tunnel under the fences. Camp Barkeley was declared surplus in 1945.

Named for World War I Army Colonel Elmer J. Wallace, Camp Wallace was established as a training facility for military personnel during World War II. The U.S. Government acquired more than 3,300 acres of land between the towns of Hitchcock and Alta Loma on State Highway 6 for placement of the facility.

Construction began in November 1940. Before the erection of structures, 17 miles of access roads were built, 29 miles of electrical lines were installed, and a 2.9-mile spur rail track from the main rail line were laid. The site contained a total of 399 structures. Some buildings were constructed at Galveston's Fort Crockett and transported to the site, including a cold storage depot, bakery, laundry, and morgue. The camp contained a medical facility, 161 barracks, and a service club.

By May 1941 the camp accommodated 10,250 people, including officers, enlisted personnel, and civilian staff. Training continued through World War II. The site also housed German prisoners of war. In April 1945, Camp Wallace was transferred to Naval supervision, and later served as a distribution center releasing veterans back into civilian life. The site was used by the Red Cross in 1947 following the explosions at Texas City. The camp was declared surplus by the U.S. Government in 1947.

The Civilian Conservation Corps Company 2888 was transferred here from Tyler in May 1941 to develop Possum Kingdom State Park. The CCC enrollees cleared the park area and shoreline, laid a waterline, built campsites and picnic tables, constructed culverts and more than seven miles of Park Road 33. The CCC camp included barracks for 200 men, a library/recreation building, a kitchen/mess hall, shops, a classroom and infirmary. Closed July 13, 1942, with the advent of World War II, this was the last CCC Camp in Texas. The park continues to serve the region.

Prior to the establishment of the town of San Saba, a group of citizens formed a Baptist congregation which met in homes three miles east on Simpson Creek. Formed in 1856, the congregation was served by missionary preacher T. Howard (1817-1882). The members agreed to move their church to town as soon as the site was determined. When the first San Saba Courthouse was completed in 1857, the Baptist congregation began meeting there, continuing until 1878, when they met in a small schoolhouse. In 1883, under the guidance of The Rev. McHenry Seal (1877-1957), a church building was erected at 307 E. Storey Street. A parsonage was added in 1899. Both structures were destroyed by fire in 1923. A building fund was started, and in 1924 the present site was acquired and a new church was begun. The basement construction was of marble donated by a local quarry, which closed due to financial troubles. The building was completed using red brick. A native stone parsonage was built in 1932. In 1947, an educational facility was added, using converted barracks purchased from Fort Hood. A new educational wing was built in 1973, and the sanctuary was remodeled in 1982.

R.A. Hindman, who started the first newspaper in Kaufman, moved to the area in 1861. With his direction, this congregation was organized the same year. Services were conducted in homes until 1877 when members bought a sanctuary at the corner of Shannon and Houston streets from the Presbyterian church. A two-story residence at 504 S. Houston, acquired in 1956, served as an educational building until fire destroyed it in 1961. Later that year the church began worshiping at this location in remodeled barracks moved from Love Field in Dallas.
