MEANS OF DEFENSE AGAINST SUBMARINE ATTACK 15t
That the submarine may wage war against submarine
is quite possible but highly improbable, as it entails the
almost certain destruction of both craft. No man has
as yet been able to devise any means for penetrating the
murky depths of the sea as far as vision is concerned, and
it is this utter blindness under water that prohibits con-
flict of submarine versus submarine. Men have clashed
before in utter blackness, however, and it may be that
when put to desperate undertaking, some young dare-
devil will stake his own life and those of his crew upon
the wheel of chance and tempt the fates with this new
kind of warfare.
If this sort of conflict is ever resorted to, it will prob-
ably resolve itself into a jockeying for position on the
part of the opposing commanders, with the purpose of
each to get his opponent broadside exposed to a heaclon
attack by himself and to ram. The opportunity for use
of the torpedo would be practically nil under these cir-
cumstances and this weapon would probably be reserved
for bigger game. Friend might be distinguished from
foe by sound signals. This would of course betray the
position of the submarine to its opponent as well, but
sound signalling would undoubtedly be resorted to at
intervals at any rate as a decoy to draw on the opponent;
it naturally being the policy of the commander to change
his position immediately a signal is sounded.
At the best this mode of fighting must remain an
unsatisfactory sort of game of blind-man’s-buff, and
would not be generally undertaken at the present time.
Future inventions for delicate and accurate direction in-
dicators to be used in conjunction with magnetic or
vibratory submarine sound receivers are quite possible
