The eldest of the three brothers, who "risked their lives and fortunes with Columbus in his doubtful enterprise," the first voyage to the unknown hemisphere, was Martin Alonzo, who commanded the _Pinta_. He ran counter to the commands of Columbus when off the coast of Cuba, and as a result fell into disgrace with the Spanish sovereigns, and died of chagrin soon after the first voyage was over. Columbus seemed to consider himself released from any obligations to the Pinzons, owing to the defection of Martin Alonzo, and they never received a single maravedi for their assistance at the most critical juncture of the Admiral's fortunes. As captain of the _Nina_, Vicente Yanez, the younger brother, stood by Columbus loyally, all through the voyage, and after the wreck of the flag-ship, off the north coast of Haiti, took his commander aboard the little caravel and brought him safely back to Spain. He seems to have received no recognition from Columbus, either for his pecuniary aid or loyal support to him in time of disaster, and after the voyage was accomplished he sank out of sight for a while, to emerge again in 1494 or 1495. About that time, says a learned historian, "Ferdinand and Isabella began to feel somewhat disappointed at the meagre results obtained by Columbus. The wealth of Cathay and Cipango had not been found; the colonists who had expected to meet with pearls and gold growing on bushes were sick and angry; Friar Boyle was preaching that the Admiral was a humbug, and the expensive work of discovery was going on at a snail's pace. Meanwhile, Vicente Yanez Pinzon and other bold spirits were grumbling at the monopoly granted to Columbus, and begging to be allowed to make ventures themselves. "Now, in this connection, several documents preserved in the archives of the Indies at Seville are very significant. On April 9, 1495, the sovereigns issued their letter of credentials to Juan Aguado, whom they were about sending to Hispaniola to inquire into the charges against Columbus. On that very day they signed the contract with Berardi [Vespucci's partner], whereby the latter bound himself to furnish twelve vessels, four to be ready at once, four in June, and four in September. On the next day they issued the decree throwing open the navigation to the Indies and granting to all native Spaniards, on certain prescribed conditions, the privilege of making voyages to the newly found coasts.
