After two years of non-stop war between Earth and the Luigi's, Jeb had had enough. He traveled right outside the main oil field, and went inside unarmed, saying that he will tell his entourage when it was safe. Five minutes later, they went and saw him standing on a pile of dead Luigis.
The leaders of the Luigi Brotherhood, knowing that they might meet the same fate, unconditionally surrendered to Jeb and his forces. Nobody knows what Jeb did to them.
