Carlo di Borgogna is an Italian opera (melodramma romantico) in three parts composed by Giovanni Pacini to a libretto by Gaetano Rossi.

Part One The people of Burgundy have come to greet Carlo “il temerario” (Charles the Bold) from his quelling of the citizens of Liège.

Lord Athol then arrives with a letter from England, reminding Carlo of his promise to marry Leonora, the sister of Edward IV.

Leonora arrives in Burgundy (Cavatina, Vago ciel del caro sposo) and is not exactly pleased when Carlo is late for their immediate wedding ceremony.

She suddenly appears to confront him with his crime, despite his protestations of continued love (Duetto-finale, L’ombra mira di colei).

Leonora, still dressed as a knight, is captured by Guglielmo, but just as the troops call for her death, Estella appears as the “angel”, heavily veiled.

Leonora is forced by Guglielmo to watch as Arnoldo cuts him down, and Carlo's body falls into the gorge below as the Swiss troops hurl the boulders down onto the Burgundian army.

Estella recognises Arnoldo long enough to fall dead in his arms, and the opera ends with the Swiss celebrating their victory (Finale, Vi salvate: il tradimento).
