The official account differs from several later recollections of Dreadnought's ramming attack. It describes one pass followed by a return to inspect the result. Some engineering memoirs recall the machinery being thrown into reverse, producing the claim that the battleship crossed the submarine twice. The disagreement shows how even famous actions can retain competing eyewitness traditions.
