Duane's take
Here's how the official marker tells it, and I'll do my best to do it justice. Way down in Cameron County, on a point of land where the Gulf Coast bends and the water does the work, there's a story that goes back further than most folks think to start it. A Mexican village grew up on this very point — ranchers, settlers, people who'd worked this land since the seventeen hundreds.
Then, quiet as the tide going out, that village was abandoned. Gone before the U.S. Declaration of war with Mexico in 1846.
Just... empty. Waiting. And sure enough, something came to fill it.
On March 24, 1846, U.S. forces led by General Zachary Taylor moved onto that point and claimed it. Taylor being Taylor, he didn't waste time on ceremony. He set up a depot right there to receive supplies rolling in all the way from New Orleans — because when you're running a military operation on the edge of the continent, you'd better have your supply line sorted out before anything else.
Now here's where it gets interesting. They built a fort — six sides to it, which ought to tell you they were thinking carefully about the geometry of the place. Four of those sides were earthen embankments, solid and deliberate.
The other two? Open to the shoreline. The water itself was part of the defense.
They named it Fort Polk, for President Polk. Well, wars end, and armies move on. Fort Polk was abandoned in 1850.
But something funny happens when you build a fort in the middle of nowhere — people follow. The settlement the fort attracted kept growing, kept taking shape, and it eventually developed into what is now Port Isabel. The fort itself faded slow.
Remnants of it were still visible until the nineteen twenties. Nearly seventy years of earthworks stubbornly refusing to disappear, as if the land wanted you to remember that a Mexican village came first, that a general set up shop on a windy point, and that a city grew up in the footprint of a six-sided fort with the Gulf wind coming through two open sides. That's how stories become places.
What the marker says
A mexican village developed on this point, settled by mexican ranchers in the 1700's. The village was abandoned prior to the U.S. Declaration of war with Mexico in 1846. U.S. forces led by general Zachary Taylor occupied the point on March 24, 1846. Taylor erected a depot here to receive supplies from New Orleans. The six-sided fort, named for President Polk, consisted of 4 sides of earthen embankments and 2 sides open to the shoreline. The fort was abandoned in 1850 but the settlement it attracted eventually developed into Port Isabel. Remnants of the fort were visible until the 1920s. (1995)
