Henry Frederick, Prince of Wales
In early 1611 Sir Thomas Roe, on a mission to the West Indies for Henry Frederick, Prince of Wales, sailed his 200-ton ship, the "Lion's Claw", some up the Amazon, then took a party of canoes up the Waipoco (probably the Oyapock River) in search of Lake Parime, negotiating thirty-two rapids and traveling about before they ran out of food and had to turn back.
