We came to the surface like bubbles in a glass of champagne""----Thus one of the earliest escapes from a stricken submarine (in Kiel in 1850) is described in this neat, well-written compendium of underwater escape since that time. The author, an expert on submarine escapes for the British Navy, knows whereof he speaks. Not only has he studied minutely such submarine disasters as K-6, Rucumilla, Squalus or Thetis, but he has actually been on the scene to direct rescue operations in many of the cases. In language any layman can understand, he tells how the first tube escapes were effected, then how specially-built crane ships, the Momsen lung, and the McCann diving bell were perfected to save men from the deep. His chapter on preparing a frogman attack on the German battleship Tirpitz in World War II makes especially good reading. The text is made more understandable with simple diagrams of equipment, plus a series of photographs, some of them of early submarines os grotesque in appearance they look like nothing less than ominous sea monsters broaching the surface.
