Duane's take
The official marker tells it this way, and I'm just the one passing it along. Now, you're rolling through Eagle Pass, Maverick County, and the ground beneath your wheels has got a story older than the town's name — older, even, than the town itself. It starts in 1849, when the United States Army planted Fort Duncan two and a half blocks south of this very spot.
And the moment that fort went up, travelers started noticing the ground nearby. Good ground. Flat, open, positioned just right.
Word got around fast among a particular breed of restless soul — the forty-niners. These weren't your standard California-bound dreamers cutting straight across the American Southwest. No, these were emigrants threading a different needle entirely — down through Mexico, through Saltillo, through Parras, then pushing on toward Chihuahua and the Gila River, or swinging west all the way to Mazatlán to catch a ship and finish the whole adventure by sea.
This spot became their camp ground, their staging area — the place where you gathered yourself before the hard part. But here's the thing about geography: it doesn't stay secret. About two miles downstream, a little settlement called Paso del Águila had already sprung up in 1848, built right along an old smugglers' trail.
Those settlers had found their footing on that trail, but footing and opportunity aren't always the same thing. The trade advantages of California Camp must've been plain enough, because those settlers soon picked up and moved here. Then, in 1850, a San Antonio landowner by the name of John Twohig stepped in, laid out a proper townsite on this ground, and gave it a name.
He called it Eagle Pass. And that name has been holding its ground ever since.
What the marker says
After founding of Fort Duncan (2.5 blocks south) in 1849, this site was a camp ground and staging area for California emigrants. These were forty-niners going through Mexico – via Saltillo and Parras – either to Chihuahua and Gila River or to Mazatlán to finish the journey by sea. Paso del Águila (2 miles downstream) had sprung up in 1848 on an old smugglers’ trail. Its settlers soon moved to California Camp for trade advantages. Landowner John Twohig of San Antonio in 1850 laid out a townsite here and named it Eagle Pass. (1969)
