He led a force of 300 men of color, using guerrilla tactics against Dutch forces, and played important roles in the First and Second Battles of Guararapes.  For his courage and leadership in battle, the Portuguese king made him a knight of the Order of Christ.  He was granted in Brazil the title of "Governor of All Creoles, Blacks, and Mulattoes."

The controversial installation consists of a Confederate flag hanging from a noose at a 13-foot gallows.  "The Proper way to Hang a Confederate Flag" was first shown in Schmucker Gallery at Gettysburg College in 2004 as a part of Sims' "Recoloration Proclamation: The Gettysburg Redress".

Included in the exhibition are recolored Confederate flags, a Confederate flag hanging from the gallows, a contemporary rewrite of the Gettysburg Address, contemporary recordings of the song "Dixie", and a documentary film.  A notable piece featured in the exhibition "Recoloration Proclamation: The Gettysburg Redress" is "ReVote," an installation featuring three voting booths used in Florida's disputed 2000 presidential election with re-colored Confederate flags hanging above, including black, red, and green for the Pan-African Flag of the African Liberation Movement.  Pink and lavender Confederate flags with feathers and sequins were also created for the exhibition signifying "drag flags".
