ANTISUBMARINE WARFARE.

NOTES FOR THE USE OF NAVAL ARMED GUARDS.


The submarine had no value as a war machine until the invention of the periscope. By the use of the periscope, partial invisibility was obtained in delivering the attack, thus giving the submarine the power of "ambush," or of making the surprise attack. The surprise attack is the reason for the submarine's existence, for without it, the submarine degenerates into slow moving torpedo boat with all its limitations.

Thus, to combat the submarine, if we prevent it from delivering this surprise, we destroy its effectiveness. In the protection of merchantmen, it should be our aim to prevent the surprise, for it is known that if the submarine once located, by maneuvering, we have a fair chance of escaping the danger of being torpedoed.

By arming merchantmen, we keep the submarine submerged, thus confining it to low speeds of small radius and preventing it from using its guns as a surface vessel.

The main points to be considered, then, are as follows...
