Pedro de Vera was described by contemporaries as an expert in fighting battles on land and sea. He led raids against the Moors in North Africa and in 1483 completed the conquest of Grand Canaria, one of the major islands of the Canaries. He was appointed military governor of the island and used his position to capture Canary natives (Guanches) and sell them as slaves in Spain. When natives on the neighboring island of Gomera revolted, he brutally put down the rebellion, killing males over the age of fifteen and selling the women and children into slavery. He was heavily fined for his actions and recalled to Castile in 1490. Cabeza de Vaca would have heard of these exploits growing up; many years later he named a province in South America, Vera, in honor of his grandfather.
