I once read an interesting text about his deposition. I believe that it was part of the book by Dr. White.
It discoursed about some frictions that he had with the Modernist that they sent to replace him. It was nothing doctrinal, as a discussion at this point would be senseless, but I recall that the good bishop was even accused of stealing forniture.
The priests of Campos had an important apostolate in some portions of the country. This was before I discovered Tradition, but I believe that it was because of their presence that the SSPX only came to Brazil in 2003 or so.
