Sols had made a voyage to the Americas in 1508, before being commissioned to lead an expedition to an area 1,700 leagues (about 5,000 miles) south of the Isthmus of Panama and beyond. He led three vessels from Sanlcar de Barrameda, Spain, on Oct. 8, 1515, with a crew of 70 men and provisions for 2 1/2 years. In February 1516 he reached the estuary of Ro de la Plata, which he called Mar Dulce (Fresh Sea). The first island he reached therein was named Martin Garcia, after one of his crewmen who had died. Sailing up the Uruguay River, he landed on the east bank (modern Uruguay) and was attacked by the Charra Indians of the region. He and the rest of the landing party, except for one man, Francisco del Puerto, were killed and eaten in sight of the remaining crewmen on shipboard. Puerto was made prisoner and later gave valuable information about the area to Sebastian Cabot, who arrived there in 1526.
