The exploration was led by Pánfilo de Narváez, who was appointed to rule as adelantado. The crew initially numbered about 600, including men from Spain, Portugal and Italy. Making stops along the way to Florida at Hispaniola and Cuba, the expedition suffered a hurricane, among other storms. After landing near Tampa Bay, they were subject to attacks by American Indians, and suffered the effects of poor food and disease. By September 1528, following an attempt to sail from Florida to Mexico, only 80 men survived after being swept onto Galveston Island, Texas. Over the next few years, more men died, and only four of the original party survived.
