More than a year later the great Columbus himself, on his fourth and last voyage, sighted the Central American coast at Cape Gracias a Dios, near the present boundary between Nicaragua and Honduras. Thence he sailed south-east along a pestilential shore for eight hundred miles, finally arriving near the point where Bastida had left off his explorations. It is said that Bartholomew Columbus founded a settlement on the Atlantic shore of the Isthmus, but it was soon destroyed by the neighbouring Indians. The long stretch of coast was unfit for the abode of Europeans, but the Indians had gold in abundance, and the Spaniards were satisfied that the interior was full of mines. Hundreds of fortunate adventurers had accumulated fortunes in the placers of Hayti, and with a view of repeating their successes on the mainland, Alonso de Ojeda solicited and obtained from the Spanish Crown the grant of the territory from Goajira to the Atrato, while Diego de Nicuesa was given the coast from the Atrato to Cape Gracias a Dios. In 1510 one of Ojeda's lieutenants founded a town called Sebastian on the eastern shore of the Gulf of Darien. The Indians soon destroyed it, but Antigua was established across the gulf. This place was in fact on the Isthmus of Panama, and not much more than one hundred miles from the Pacific Ocean, of which the Spaniards then knew nothing. Among the military adventurers who had followed Ojeda to Darien were Nunez de Balboa and Francisco Pizarro. In 1511 the former went a short distance into the interior looking for gold, and fell in with an Indian chief who told him that only a few leagues south lay a great sea whose shores were inhabited by numerous rich and civilised nations. Two years later he headed an expedition from Antigua which resulted in the epoch-making discovery which has immortalised his name. As the band of Spaniards approached the line of hills from which the natives told them they could see the mysterious ocean, Balboa hastened ahead of his men and was the first to catch a glimpse, but in the headlong rush for the honour of first touching its waters he was beaten by Alonso Martin and that lean and tireless soldier who was afterwards to conquer Peru--Francisco Pizarro.
