Later years and death

Upon Cabral's return, King Manuel I began planning another fleet to make the journey to India and to avenge the Portuguese losses in Calicut. Cabral was selected to command this " Revenge Fleet ", as it was called. For eight months Cabral made all preparations, but for reasons which remain uncertain, he was relieved of command. It had apparently been proposed to give another navigator, Vicente Sodré, independent command over a section of the fleet, and Cabral strongly opposed this. Whether he was dismissed or requested himself that he be relieved of command, the result was that when the fleet departed in March 1502, its commander was Vasco da Gama—a maternal nephew of Vicente Sodré—and not Cabral. It is known that hostility had developed between a faction supporting da Gama and another supporting Cabral. At some point, Cabral left the court permanently. The King was greatly irritated by the feud, to such an extent that mentioning the matter in his presence could result in banishment, as it did for one of da Gama's supporters.

Despite the loss of favor with Manuel I, Cabral was able to contract an advantageous marriage in 1503 to Dona (Lady) Isabel de Castro, a wealthy noblewoman and descendant of King Dom Fernando I of Portugal. Her mother was a sister of Afonso de Albuquerque, one of the greatest Portuguese military leaders during the Age of Discovery. The couple had at least four children: two boys (Fernão Álvares Cabral and António Cabral) and two girls (Catarina de Castro and Guiomar de Castro). There were two additional daughters named Isabel and Leonor according to other sources, which also say that Guiomar, Isabel and Leonor joined religious orders. Afonso de Albuquerque attempted to intercede on Cabral's behalf and on 2 December 1514 asked Manuel I to forgive him and allow his return to court, but to no avail.

Suffering from recurrent fever and a tremor (possibly malaria) since his voyage, Cabral withdrew to Santarém in 1509. He spent his remaining years there. Only sketchy information is available as to his activities during that time. According to a royal letter dated 17 December 1509, Cabral was party to a dispute over a transaction involving property which belonged to him. Another letter of that same year reported that he was to receive certain privileges for undisclosed military service. In 1518, or perhaps previously, he was raised from fidalgo to knight in the King's Council and was entitled to a monthly allowance of 2,437 reais. This was in addition to the annual allowance granted to him in 1497, and still being paid. Cabral died of unspecified causes, most probably in 1520. He was buried in the São João Evangelista chapel of the Convento da Graça in Santarém.
