Slaughtering and eating their remaining horses, they gathered the stirrups, spurs, horseshoes and other metal items. They fashioned a bellows from deer hide to make a fire hot enough to forge tools and nails. They used these in making five primitive boats to use to get to Mexico. Cabeza de Vaca commanded one of these vessels, each of which held 50 men. Depleted of food and water, the men followed the coast westward. But when they reached the mouth of the Mississippi River, the powerful current swept them out into the Gulf, where the five rafts were separated by a hurricane. Some lives were lost forever, including that of Narváez.
