After Leif Eriksson made his trip to America, his brother Thorvald did the same. His crew soon clashed with Native Americans. We read about these encounters in the 13th century manuscript called "The Saga of the Greenlanders"
At some point, they saw “three hide-covered boats with three men under each of them. They divided their forces and managed to capture all of them except one [...]. They killed the other eight.”
Soon after, a vast number of these boats came for them. The natives (called Skraelings by the Vikings) shot at them with arrows. Thorvald was hit: “An arrow flew between the edge of the ship and the shield into my armpit. Here is the arrow, and this wound will cause my death.”
