Feb. 05 (UPI) -- On this date in history: In 1631, British clergyman Roger Williams, who founded the colony of Rhode Island, arrived in Salem, Mass., seeking religious freedom. In 1918, a German U-boat torpedoed the SS Tuscania, sinking the liner as it transported thousands of U.S. troops to Europe. More than 200 died, the rest were rescued by other ships in the convoy.
