His hour of rest, however, was not yet come. Ever anxious to serve their Catholic Highnesses, "and particularly the Queen," he had determined to find a strait through which he might penetrate westward into Portuguese Asia. After the usual inevitable delays his prayers were granted, and on May 9, 1502, with four caravels and 150 men, he weighed anchor from Cadiz and sailed on his fourth and last great voyage. He first betook himself to the relief of the Portuguese fort of Arzilla, which had been besieged by the Moors, but the siege had been raised voluntarily before he arrived. He put to sea westward once more, and on June 13th discovered the Island of Martinique. He had received positive instructions from his sovereigns on no account to touch at Espanola, but his largest caravel was greatly in need of repairs, and he had no choice but to abandon her or disobey orders. He preferred the latter alternative, and sent a boat ashore to Ovando, asking for a new ship and for permission to enter the harbor to weather a hurricane which he saw was coming on. But his requests were refused, and he coasted the island, casting anchor under lee of the land. Here he weathered the storm, which drove the other caravels out to sea and annihilated the homeward-bound fleet, the richest till then that had been sent from Espanola. Roldan and Bobadilla perished with others of the Admiral's enemies; and Hernando Colon, who accompanied his father on this voyage, wrote, long years afterward, "I am satisfied it was the hand of God, for had they arrived in Spain they had never been punished as their crimes deserved, but rather been favored and preferred."
