Columbus then sailed along the north coast of the island and entered the pretty little port known to-day as Port-a-l'Ecu. Here, on December 12, he solemnly took possession of the country in the name of his sovereigns, erecting a wooden cross on a high hill on the western side of the bay. He then visited Tortuga Island, to the north, giving it this name on account of its shape and the great number of turtles in the water near its coast. After stopping in a harbor which he called Puerto de Paz, Port of Peace, because of the harmony which prevailed at the meetings with the natives, Columbus continued in an easterly direction, but adverse winds compelled him to put into the bay of Santo Tomas, to-day bay of l'Acul, where the cordial intercourse with the natives was renewed. Here he received an embassy from the chief of the district, Guacanagari, inviting him to visit the cacique's residence, further along the coast, and bringing him as presents a wampum belt artistically worked and a wooden mask with eyes, tongue and nose of gold. To accept the invitation Columbus set sail on the morning of December 24. In the evening when the admiral had retired the helmsman committed the indiscretion of confiding the helm to a ship's boy. About midnight when off Cape Haitien, near their destination, the vessel was caught in a current and swept upon a sandbank where she began to keel over. During the confusion which followed, Columbus had the mainmast chopped down but all efforts to right the ship were in vain, and Columbus and the crew were obliged to take refuge on the little Nina. As soon as Guacanagari received news of the disaster he sent large canoes filled with men to help the strangers transport their stores to the shore. The relations between the Spaniards and the Indians became most cordial, especially as the Spaniards were gratified to obtain much gold in exchange for articles of insignificant value, owing to which circumstances and to the natural advantages of the location, Columbus determined to build a fort with the wreckage of his vessel. The fort was on a hill east of the site of the present town of Cape Haitien. Columbus gave it the name of La Navidad because he had entered the bay on Christmas day, and leaving thirty-nine men as colonists set out on the Nina on January 4, 1493, on his return trip to Spain.
