Ralph Henry Barbour,
For the Freedom of the Seas — Chapter 17
(1918)
“ Those destroyers were new at the game and filled with enthusiasm, and half a dozen times that day the sharp bark of three-inch or four-in guns added to the joy of life. When it wasn't inanimate wreckage that made a lookout gasp and shout incoherently it was a porpoise. A porpoise appearing suddenly near the bow suggests just one thing in the world, and it isn't "Porpoise!" It's "Torpedo!" The Gyandotte was theoretically blown to bits at least five times that day by playful porpoises! ”
