In his commission Grijalva had been directed to discover and explore new lands, and to take possession of them for the King of Spain, but he was forbidden to undertake colonization of them or to make any permanent settlements. To that prohibition must be ascribed the practical failure of his expedition. He appears to have realized the desirability of making permanent settlements, but felt himself restrained by his orders. His men murmured and almost mutinied because they were not permitted to build forts, take land, and establish colonies; but Grijalva, though firm to resist them, dared not violate the orders of his uncle. However, at midsummer he sent Alvarado back with two ships, carrying the sick and wounded, and also much treasure in gold which had been obtained from the natives in barter. He likewise wrote to Velasquez, asking and indeed urging that his commission be so amended as to permit him to make permanent settlements in the lands which he had discovered. It does not appear that Velasquez made a favorable response to this request, if indeed he made any at all. He had previously manifested his impatience to learn what Grijalva was doing and what he had found, by sending Christopher de Olid with one vessel to offer him reenforcements and supplies, if needed, and to get a report of his achievements. Off the Mexican coast, however, that expedition ran into a succession of violent storms which so discouraged and dismayed Olid that he abandoned his errand and scuttled incontinently back to Cuba without so much as communicating with Grijalva. The latter, accordingly, after spending the summer and early fall in Mexico, and despairing of receiving the increased authority which he deemed essential to the further success of his expedition, reembarked and returned to Cuba, arriving at Matanzas early in October. There he found Olid, who had reached that port only a few days before, and who had not yet communicated with Velasquez the news of the failure of his errand. Olid's report to Velasquez, which was then promptly dispatched, contained therefore the news of Grijalva's return as well as his own. As soon as he received this, Velasquez sent word to Grijalva to come at once to Santiago and report to him in person, but to let his men remain at Matanzas, or at Havana, since he wanted them to serve in another Mexican expedition which he was already fitting out. Most of the men were willing to do this, and were accordingly maintained there at the cost of Velasquez, or of the Spanish Crown, until he was ready to use them; though a certain number expressed themselves as having had their fill of exploring and accordingly returned to their homes in various parts of Cuba.
