Marker Inscription
The Battle of Lake Pontchartrain. On October 16, 1779, the British living between "Bayou La Combe and the River Tanchipaho," surrendered to Captain William Pickles who had won a naval battle off this shore on September 10, 1779, and thereby ended the Revolutionary War in Louisiana.

The Story
On September 10, 1779, Captain William Pickles won a naval fight off this shore, and on October 16 the British living between Bayou Lacombe and the Tangipahoa River formally surrendered to him. The action helped bring the Revolutionary War's Gulf Coast fighting to a close in Spanish Louisiana. It was part of the wider struggle in which Spain, allied against Britain, pressed the British out of the lower Mississippi region.
Why it matters
It marks a little-known Gulf theater of the American Revolution, where the war's outcome turned on Spanish and allied action far from the eastern battlefields.
The story behind this marker
AI contextThe era
When most Americans picture the Revolution, they see New England commons and Virginia farmland. But the war for independence had a southern flank along the Gulf Coast, and in 1779 it turned hot. That year Spain entered the conflict against Britain, and Spanish Louisiana became a front line.
The lower Mississippi and the shores of Lake Pontchartrain sat at the seam between British West Florida and Spanish territory. Control of these waters meant control of trade, communication, and the ability to move troops — and both empires knew it.
So the fighting that reached this shoreline was part of a much larger contest. Spain's forces, led from New Orleans, pressed hard against British positions in the region, and the American cause benefited from every British soldier and ship tied down here rather than sent north.
People & events
The name attached to this place is Captain William Pickles. On September 10, 1779, he won a naval engagement off this very shore — a small but decisive action in the sheltered waters of the lake.
The victory had consequences on land as well as water. On October 16, 1779, the British inhabitants living in the stretch of country between Bayou Lacombe and the Tangipahoa River formally surrendered to Pickles. With that submission, organized British resistance in this part of Louisiana came to an end.
It was the kind of episode the big histories often skip: no famous general, no vast army, just a determined captain, a stretch of contested lakeshore, and a surrender that closed out a campaign. Yet for the people who lived between those two waterways, it settled the question of who ruled.
Its place in the American story
This marker preserves the memory of a Gulf theater where the Revolution's outcome depended on more than the Continental Army. Here the war advanced through Spanish and allied action, far from the eastern battlefields, as part of the global effort to strip Britain of the manpower and momentum it needed.
Every British force pinned down along the Gulf was one that could not reinforce the fighting elsewhere. Victories like the one commemorated here helped ensure that the lower Mississippi and its lakes did not become a secure British base — a strategic outcome that mattered well beyond Louisiana.
It is a useful corrective to the tidy story of thirteen colonies acting alone. Independence was won inside a wider war, and this quiet shoreline is one of the places where that wider war was decided.
If you visit
Stand at the edge of Lake Pontchartrain and let the water do the storytelling. The lake looks placid today, but this is where a Revolutionary-era naval fight played out, and where a British surrender followed a month later. The distances named on the marker — from Bayou Lacombe to the Tangipahoa River — trace a real span of coast you can picture from the shore.
There is little of a battlefield to see, because a naval action leaves no earthworks. What you get instead is place and perspective: the same open water, the same horizon, the sense of how far this fight sat from the more famous ones.
Mandeville's lakefront makes it a pleasant place to pause. Bring the surprise with you — that the American Revolution reached all the way to this Gulf shore — and the view becomes a good deal more interesting.

Lafayette Square
New Orleans, LA
Laid out in 1788 as the public square of Faubourg Ste. Marie, New Orleans' first suburb, this green honors the Marquis de Lafayette, the French nobleman who fought for American independence. He declined an offer to become the first governor of the Louisiana territory the United States had just purchased, but on his triumphal 1825 tour he was met here with cries of 'Vive Lafayette!' A French-American society dedicated the marker in 1985.
Battle of Baton Rouge (1779)
Baton Rouge, LA
In September 1779 the fighting of the American Revolution reached the Gulf Coast, where Spanish forces under Governor Bernardo de Gálvez captured the British-held fort at Baton Rouge. As Spain's ally-in-effect against Britain, Gálvez opened a southern front far from the thirteen colonies, and this marker recalls the men who fought there. It stands as a reminder that the Revolution was won on a wider map than the eastern seaboard alone.
