USS Vulcan

The USS Vulcan was a U.S. Navy fuel ship. At the start of the Great War, she was part of the American Pacific Fleet during their successful operation to take the Sandwich Islands. She was pumping heavy fuel oil into the Dakota when the fleet went to battle stations after an aeroplane was spotted. It turned out to be an American scout plane that had been launched several hours earlier but the Vulcan and the other support ships fell back to let the warships do their job.
