The Mary Rose was an English warship that sank mysteriously—and probably accidentally—during a battle in 1545. The ship was leading an attack on an invading French fleet when, quite suddenly, it heeled over to one side and sank with about 400 crew members on board. It was rediscovered in 1971. When it was raised in 1982, there were still 92 complete skeletons inside. Maritime researchers believe that it probably sank because the sailors failed to do what? Discuss
