The Story
Gully Cowsert served as a Marine Corps corporal in World War I before finding his lasting calling as a Texas Ranger, a badge he earned in 1942 and wore for fourteen years. He rose to command Company E and West Texas District, building a reputation for cracking cattle- and sheep-theft cases across the rangelands. His career bridged the mud of a world war and the enduring frontier tradition of the Ranger lawman.
Why it matters
Cowsert embodies the twentieth-century Texas Ranger, carrying the legend of frontier law enforcement into the age of the automobile and the modern livestock economy.
The story behind this marker
AI contextThe era
Gully Cowsert was born in 1896, and his life covered a remarkable stretch of Texas history. He came of age just as the United States entered World War I, when young men from ranch and farm country across the state went into uniform.
By the time he became a Texas Ranger in 1942, the force had changed a great deal from its frontier origins. In 1935 the Rangers were reorganized as part of the new Texas Department of Public Safety, a step toward a more modern state police. Automobiles, telephones, and highways had transformed how lawmen worked.
Much of West Texas, including the Hill Country around Junction, was ranching country, and sheep and goat raising were major industries on the Edwards Plateau. In a region like that, livestock theft was a serious crime, and it struck directly at a rancher's living.
People & events
Cowsert served as a corporal in the U.S. Marine Corps during World War I, part of the generation that answered the country's call in 1917 and 1918. The marker does not tell us where he served, but the title of corporal meant he had earned responsibility for the Marines under him.
In 1942 he became a Texas Ranger and served for fourteen years. He commanded Company E and the West Texas District, and he became well known for solving cattle and sheep theft cases. That was patient, practical work: tracking stolen animals, reading brands, and knowing the country and the people in it.
His family appears on the marker as well. With his first wife, Mamie Keesee, he had two sons, K. and Gully Jr., and a daughter, Mary Katherine. He later married Dana Van der Smissen. Cowsert died on June 11, 1958, one day before his sixty-second birthday.
Its place in the American story
Few American law enforcement agencies carry as much legend as the Texas Rangers. Cowsert's career shows the less-famous middle chapter of that story, after the frontier era and after the 1935 reorganization, when Rangers did steady investigative work across enormous rural districts.
His case files also point to the ongoing importance of the livestock economy. Cattle and sheep were not relics of the Old West in the mid-twentieth century; they remained central to the livelihoods of Texans across the region, and protecting them was real, consequential police work.
Finally, his life connects two strands of the national story: the citizen-soldiers of World War I, and the veterans who came home to serve their communities for decades afterward. Many of that generation's quiet public careers are remembered only on markers like this one.
If you visit
Junction sits in the western Hill Country, where the landscape of limestone hills, rivers, and ranchland gives you a real feel for the country Cowsert patrolled. As you drive in, notice the fences and pastures. This is the kind of range where livestock theft cases were won or lost on local knowledge.
Take a moment with the marker itself and its dates, which frame a life that ran from the Marine Corps in the First World War to the leadership of a Ranger company in postwar West Texas.
Junction is a natural stopping point on a drive across the Texas Hill Country. Pair this marker with the region's courthouse towns and river crossings to trace how ranching shaped both the land and the lawmen who protected it.

Burt M. Fleming American Legion Post No. 237
Junction, TX
Founded in May 1919, this American Legion post honored a local man killed in France during the First World War and quickly became one of Kimble County's best-known organizations. In 1938 members built a native-rock home on this site, lining its walls with wartime keepsakes, and added a memorial hall after the Second World War. In 1966 the old "Legion hut" passed to the county historical museum.
Mason National Bank
Mason, TX
Founded in 1904 by pioneer settlers as the German American National Bank of Mason, this institution anchored the finances of a heavily German Hill Country community. Anti-German feeling during World War I pushed the board to rename it Mason National Bank in 1918, even as it led local Liberty Bond drives. It weathered the Great Depression through a 1932 merger and early FDIC certification.
First Church in Community Copperas Methodist Church
Junction, TX
On the West Texas frontier of 1881, the celebrated circuit rider Andrew Jackson Potter organized this Methodist congregation, part of his lifelong work planting churches across a raw and thinly settled country. For years the faithful gathered in a schoolhouse or under a brush arbor near Copperas Creek before neighbors hauled lumber by wagon from Menard and donated their own labor to raise a church here in 1917.
Coalson-Pullen Colony
Junction, TX
Nick and Jennie Coalson opened this Kimble County ranch in 1866, scratching out a living by stockraising and hunting — their "bacon" was cured bear meat. In December 1870, while the men were away hunting, raiders attacked the cabin and killed ranch hand Joe Harris; Jennie Coalson, dressed in men's clothes, held them off until her husband returned. The Coalsons later sold to Civil War veteran and surveyor Dr. Asa Pullen, whose family's descendants still live in the county.
