He was killed during the Restoration War at the Martyrdom of Cunhau, a massacre promoted by Dutch troops and their Calvinist ministers, who fought against the Portuguese Empire in Brazil.

Cunhaú was a village of Canguaretama, in Rio Grande do Norte, which was formed around a sugar cane mill, one of the riches of the region, in addition to the mines for the production of parts, since those on the other side of the ocean took too long and were expensive, with the threat of low profitability and loss of input in time to be processed by the transformation center (a kind of expansion of Paraiba and Pernambuco production to the north, which is the economic cradle of Potiguar).

On the morning of 16 July 1645, while celebrating Mass at the Parish of Our Lady of the Candles or Purification, the German Jacó Rabe broke into the church, with the excuse of communicating some provisions by the Supreme Dutch Council of Recife.

André de Soveral and Domingos Carvalho were beatified by John Paul II on 5 March 2000[3][4], together with Father Ambrósio Francisco Ferro,[5] layman Mateus Moreira and their fellow Martyrs of Natal.

[6] On 23 March 2017 Pope Francis signed a decree recognizing the miracle through the intercession of André de Soveral and his companions, and on 20 April 2017 during the consistory he set the date of their canonization.
