<span>On July 20, 1636, a trader named John Oldham was attacked on a trading voyage to Block Island. He and several of his crew were killed and his ship was looted by Narragansett-allied Indians who sought to discourage English settlers from trading with Pequot rivals. In the weeks that followed, colonial officials from Massachusetts Bay, Rhode Island, and Connecticut, assumed the Narragansett were likely culprits.

SO in he end It was Oldham's death that caused the Pequot War.</span>
