Footnotes

• Please note that this work was reproduced in the 4th September 1943 edition of The Sphere. It is accompanied by a note as follows:
  'The difficulty of catching enemy craft in the Mediterranean at night. Even on a moonlit night it is possible for vessels to pass quite close to each other without being seen. Naval observers have declared that the best way to spot enemy ships is by the phosphorescent wake they leave behind: this tell-tale trail cannot be obliterated for a long time after the ship has passed, especially if it is travelling at speed. When conditions are favourable, the moon will light up the ship's wake and thus point the way for the pursuing naval vessels.'
