Note 32 — III THE LANDING
Reading edition
Submarine wire entanglements are being used effectively for the protection of harbors during the present war. The wire cannot resist cutting much more than twine can. It stops the submarine by menacing it with being entangled and trapped. A submarine caught under water cannot be cleared by its crew. The utmost the men can do is to try to reach the surface by putting on “special escape helmets” and emerging through the air-locks.
