In 1843, an 11-mile stretch of bayou country in southern Louisiana was erased from official maps in a single afternoon. Bayou Marchesseau, a blackwater channel connecting two old French trading posts, was removed from the parish record by a clerk named August Delahoussaye, who resigned three weeks later and never spoke of the matter again. The erasure followed an expedition organized by the Vermilion Land and Drainage Company, a New Orleans private partnership formed in late 1839 to survey roughly 40,000 acres of swampland for sugarcane cultivation. Chief surveyor Cyprien Van der Veghe, a Belgian-born engineer of 37, led a party of eleven men into the bayou on March 2, 1840.
Only four returned. Among the men were Van der Veghe’s apprentice Octavian Boudreau, three Acadian trappers, two German laborers named Friedrich and Wilhelm Hauschildt, a freedman boatbuilder named Solomon Cordeau, two armed escorts known only as Mugeot and Pelequin, and a Catholic missionary identified as Father Innocencio Aldrete, who had requested to join the expedition to minister to isolated settlers. The first six days of the journey were unremarkable. Van der Veghe kept a field notebook recording water depth, tree types, and wildlife until March 7, when he wrote a single line cited later in court documents: “We are now beyond the last cabin.
From here, we are alone. ”
On the night of March 10, one of the trappers, Théodule Babineau, reported hearing what sounded like a child crying somewhere out in the dark water. He said the sound moved slowly along the bayou over roughly twenty minutes and then stopped. There were no settlements nearby, and no children on the expedition.
Babineau heard the sound again the following night; a second trapper, Onésime Hébert, heard it as well. Father Aldrete asked Van der Veghe to consider turning back. When the surveyor refused, the priest walked into the trees to pray, returned with wet knees and something clutched in his closed hand, and locked it inside a satchel. On March 13, the party reached a fork not recorded on any previous chart.
Van der Veghe sent Boudreau, Cordeau, and Mugeot up the smaller eastern channel in a light pirogue with instructions to return by sundown. They did not return. The remaining men followed the channel the next day. Four miles upstream they found the pirogue tied neatly to a cypress root.
The provisions were untouched, Boudreau’s coat was folded on the seat, Cordeau’s pole lay across the gunnels, and Mugeot’s rifle was leaning against the bow, loaded but uncocked. The three men were gone. Footprints led from the bank about eighty paces into the trees and then stopped abruptly. That night, the surviving men began hearing voices in low, conversational tones moving in an arc around the camp.
According to three separate accounts that researchers later found remarkably consistent, the men believed there were three voices. Father Aldrete placed a wooden case at the edge of camp, knelt before it, and began reciting Latin prayers that Van der Veghe said he recognized as coming from the rite of exorcism. The voices responded by imitating the priest’s words and cadence precisely, half a beat behind him. After nearly two hours, Aldrete finished, and the voices fell silent.
The swamp went completely still. The priest told Van der Veghe, “We must leave at first light, and we must not look behind us as we go. ”
During the retreat, the pirogue carrying the German brothers and the escort Pelequin fell behind. When Van der Veghe turned back, he found the boat drifting sideways.
Pelequin was unresponsive but breathing. The Hauschildt brothers were gone; their packs, tools, and a single wet boot remained, but no trace of the men could be found on either bank. Overnight on March 16, the older trapper Théodule Babineau vanished during watch. His rifle lay on the ground and his coat was folded neatly beside it.
There were no footprints. Of the seven men lost to the expedition, only Pelequin survived the journey out. He never fully recovered; he never spoke of what had happened on the boat, and he died of a fever in 1863. Father Aldrete returned to Grand Coteau and died fourteen months later, with the parish doctor recording exhaustion of the heart as the cause.
A sealed letter he left for the bishop was reportedly read and destroyed. Van der Veghe gave an extended statement to company officials on March 25, 1840. The surviving portion runs to roughly twenty-three pages; eighteen pages of the shorthand transcript were burned by company directors before any permanent record was made. In his statement, Van der Veghe said the disappearances were not caused by an animal, a hostile party, or mental illness.
He described the bayou as a place that is “awake” and that “listens” and “chooses” whether to permit men to pass. He said he believed the missing men were not killed but “taken in” by the bayou, and he refused to return. One director ordered the testimony stricken from the report. The Vermilion Land and Drainage Company dissolved within eight months, and its files were mostly lost in a warehouse fire in 1846, which the parish coroner recorded as being of suspicious origin.
From 1843 onward, Bayou Marchesseau was no longer named on any parish chart. By the 1860s it appeared as no water at all, redrawn as low-lying ground unsuitable for survey. Local Acadian families, asked about it as late as the 1920s, would only say in French that certain places were not meant to be looked at. Van der Veghe never returned to surveying.
He moved to New Orleans, married, and operated a shop selling watch parts until his death at seventy-one. His expedition notebook, sealed in a tin box, was preserved and eventually reached a parish archivist. The final page of the notebook is dated March 20, 1840. In an unsteady hand, Van der Veghe wrote that he had been having a recurring dream in which he stood on the bank where the three men had disappeared, following a line of footprints that led into the trees.
Each night, he wrote, the footprints stretched a little farther, as if the missing men were still walking. He closed the entry with the line: “I do not know what I will do when the footprints reach the bank again. ” The notebook contains no further entries.
It records forty-one years of silence.
