Micheletto Corella (Micheletto Coreglia, Michele de Corella or Miguel de Corella) was a Valencian condottiero born on an unknown date in Valencia. He was killed in Milan in February 1508.
Known as Valentino's executioner, he and Cesare Borgia were thought to be close friends since childhood, going on to accompany one another during their studies at the University of Pisa.
On 23 December 1499, a Don Michele de Corella and the Bishop of Trani were left in Forli as lieutenants in Cesare Borgia's army around the time of the seizure of Forli.
In March, 1502, Corella was left by Cesare as his governor in Piombino. Corella was then dispatched to Pesaro with Ramiro de Lorqua under the order of Cesare Borgia in October, 1502. With his lances, on his way to Pesaro, Corella heard of the insurgence of the rebelling Fossombrone and Pergola, and ventured to those towns to sack them pitilessly as punishment.
Machiavelli describes a conversation Corella had with Oliverotto da Fermo on 31 December 1502: "Therefore Don Michele rode off and joined Oliverotto, telling him that it was not right to keep his men out of their quarters, because these might be taken up by the men of the duke; and he advised him to send them at once to their quarters and to come himself to meet the duke."
On the night of 31 December 1502, Vitellozzo Vitelli and Oliverotto da Fermo, who had been arrested under Cesare's command, were strangled to death, supposedly by Corella (hinted in Machiavelli's letter of 31 December).
In November 1503, Michele da Corella and della Volpe had gone north with seven hundred horse to support Cesare's Romagnuoli but the group were defeated in Tuscany by the army of Gianpaolo Baglioni (Rafael Sabatini, The Life of Cesare Borgia, Chapter III: Julius II) After Micheletto Corella and della Volpe were taken prisoner in 1503, Corella was first imprisoned in Florence and then in Rome where he was questioned and tortured. However, he refused to reveal the many secrets he knew about the Borgias.
