Erasmus Bentley was a white Northern Republican — a "carpetbagger" in Democratic parlance — who had come to Opelousas to teach in the freedmen's schools and who published a Republican newspaper, the St. Landry Progress. In the weeks before the 1868 presidential election, the newspaper urged Black residents to register and vote for Ulysses Grant. This was intolerable to local Democrats.
On September 28, 1868, a group of Democrats attacked Bentley's office. In the confrontation that followed, Bentley wounded several of his attackers. He fled to the house of a local Black man for protection. Democrats surrounded the house, took Bentley prisoner — and then used his act of self-defense as a pretext to declare that armed Black insurrection was underway in St. Landry Parish.
There was no insurrection. But the pretext was all that was needed. Democratic rifle clubs fanned out across the parish over the following weeks.
