How did henry the navigator for filled his mission

Henry the Navigator, Portuguese Henrique o Navegador, byname of Henrique, infante (prince) de Portugal, duque (duke) de Viseu, senhor (lord) da Covilhã, (born March 4, 1394, Porto, Portugal-died November 13, 1460, Vila do Infante, near Sagres), Portuguese prince noted for his patronage of voyages of discovery among the Madeira Islands and along the western coast of Africa. The epithet Navigator, applied to him by the English (though seldom by Portuguese writers), is a misnomer, as he himself never embarked on any exploratory voyages.
