Peter Cavanaugh Woods
San Marcos, Hays County, Texas
Marker Inscription
(December 30, 1819 - January 27, 1898) Born in Tennessee, Peter C. Woods was reared by his maternal grandparents. He graduated from the Louisville, Kentucky, Medical Institute in 1842. Woods married Georgia V. Lawshe in 1846. They moved with their children, Pinckney and Sarah Cherokee, and slaves to Bastrop, Texas, in 1852, and settled in Hays County in 1854. Dr. Woods began a medical practice in the San Marcos Area. Using a little-known aseptic technique learned in New York, he effected an excellent survival and recovery rate among his surgical patients. Dr. Woods was elected commanding officer of the 32nd Texas Cavalry Regiment in March 1862 at Camp Wood south of San Antonio. The 32nd Cavalry Regiment and other Texas Regiments kept the Union Army from invading Texas by patrolling the Rio Grande and Gulf Coast borders to protect the cotton trade with Mexico. They picked up Confederate deserters and conscription evaders. Dr. Woods became a colonel known for his loyalty to his men, once refusing an order to force the men to give up their own horses to the Confederacy. The regiment fought in Louisiana at the Battles of Blair's Landing, Grand Ecore, Mansfield, Monett's Ferry, Pleasant Hill and Yellow Bayou, where Woods himself received an arm injury which impaired him for the rest of his life. His aseptic methods saved the limbs of the wounded soldiers in his regiment. After the war, Colonel Woods returned to San Marcos. He freed his slaves, giving them tracts of land, and resumed farming and the practice of medicine. He was elected to the Constitutional Convention of 1866. After Georgia L. Woods died in 1872, he married Ella R. Ogletree in 1874. (2000)

The Story
Dr. Peter Cavanaugh Woods, a Kentucky-trained physician, settled near San Marcos in 1854 and won a reputation for a little-known aseptic surgical technique that gave his patients unusually high survival rates. In 1862 he was elected colonel of the 32nd Texas Cavalry, which guarded the Rio Grande and Gulf Coast to protect the cotton trade and later fought in the Louisiana campaigns, where Woods was wounded in the arm. After the war he freed the people he had enslaved, gave them tracts of land, and returned to medicine and farming.
Why it matters
His life joins frontier medicine, Confederate service, and the fraught transition of emancipation in a single Texas biography of the Civil War era.
The story behind this marker
AI contextThe era
Peter Cavanaugh Woods lived his defining years in the Civil War era, and his Texas was a place pulled between the frontier and the sectional crisis engulfing the whole country. Born in Tennessee in 1819 and trained in medicine in Kentucky, he brought professional skills to a young state where trained physicians were scarce and much of the population still lived close to the land.
He reached Hays County in 1854, settling into a medical practice around San Marcos in the years just before the war. Texas at that time was a slaveholding state tied economically to cotton, and Woods, like many settlers of means from the Upper South, came as a slaveholder himself. When war came in 1861, Texas joined the Confederacy, and men across the state were drawn into its armies.
Medicine in this period was on the edge of transformation. The idea that unseen contamination caused deadly infections was still new and far from universally accepted, and battlefield surgery was notoriously lethal. A doctor who understood how to keep wounds clean held, without exaggeration, the power of life and limb over the men in his care.
People & events
Woods graduated from the Louisville Medical Institute in 1842 and married Georgia V. Lawshe in 1846. In 1852 the family moved to Bastrop, Texas, and by 1854 they had settled in Hays County, where he began practicing medicine. What set him apart was a little-known aseptic technique he had learned in New York — a method of keeping surgery clean — that gave his patients an unusually high rate of survival and recovery at a time when many surgeons could not say the same.
In March 1862 he was elected commanding officer of the 32nd Texas Cavalry Regiment at Camp Wood, south of San Antonio. The 32nd and other Texas regiments spent much of the war guarding home ground — patrolling the Rio Grande and Gulf Coast to protect the cotton trade with Mexico, and rounding up deserters and men evading conscription. Woods earned a reputation for loyalty to his soldiers, once refusing an order to make his men surrender their own horses to the Confederacy.
The regiment later fought in Louisiana, at engagements including Blair's Landing, Grand Ecore, Mansfield, Monett's Ferry, Pleasant Hill, and Yellow Bayou. At Yellow Bayou, Woods himself took an arm injury that impaired him for the rest of his life. Even so, his aseptic methods are credited with saving the limbs of wounded men in his regiment — the surgeon's knowledge protecting the soldiers he led. After the war he returned to San Marcos, freed the people he had enslaved and gave them tracts of land, resumed farming and medicine, and was elected to the Constitutional Convention of 1866. Widowed in 1872, he married Ella R. Ogletree in 1874, and he lived until 1898.
Its place in the American story
Woods's life gathers several of the largest threads of nineteenth-century America into a single biography. There is frontier medicine, carried west by a trained physician to a place that badly needed him. There is the Civil War, in the particular form the war took in Texas — less about great pitched battles than about guarding borders, protecting the cotton economy, and holding a restless home front together. And there is the wrenching transition of emancipation.
His medical story matters beyond his own patients. The gradual, uneven acceptance of the idea that clean surgery saves lives was one of the great turning points in human health, and here is a working example of it on the American battlefield — a surgeon whose careful methods meant men kept their arms and legs when others in their situation would not have.
And the marker does not look away from the hardest part. Woods enslaved people, went to war for a government committed to preserving slavery, and then, after the war, freed those people and gave them land. That arc — a life that spans slaveholding, Confederate service, and the fraught aftermath — is the American Civil War era in one person, contradictions intact.
If you visit
This is a memorial, so come to it as a place for reflection rather than spectacle. The whole of a long, complicated life is compressed into a marker, and it rewards standing quietly and reading it slowly, letting the span from 1819 to 1898 register.
Hold the pieces together rather than choosing among them. The same man carried a surgical technique that saved soldiers' limbs, led a cavalry regiment and stood up for his men's horses, was wounded in Louisiana, and after the war freed the people he had enslaved and gave them land, then helped write a state constitution. History is often this tangled, and this marker doesn't tidy it up.
As part of a day exploring San Marcos and Hays County, this stop offers something the region's homes and churches can't: a single human life through which to view the whole Civil War era, frontier medicine and emancipation included. Give it a few minutes of genuine thought — that's the visit this place asks for.
