Pedro de Menezes participated and distinguished himself in the 1415 Conquest of Ceuta, and, in the aftermath, was appointed by King John I of Portugal as the first Portuguese governor of Ceuta. Allegedly, he was the only Portuguese noble willing to remain in charge of the Portuguese garrison, which was sure to be attacked by the full force of Marinid Morocco in due time. Pedro de Menezes was left with a garrison of 1600 soldiers. In 1416, Prince Henry the Navigator was placed in charge of supplying provisions to the Ceuta garrison from Portugal.
