“Who got up the idea of a submarine chaser?”
“Well, that I don’t know about, matey, but I do know that when Germany sent out her first U-boats to the coast of Great Britain to sink her ships, all sorts of motor boats which had a length of 40 feet and over were pressed into service; these boats had guns mounted in them and they combed the sea in search of the submarine enemy.
“The first German U-boats were slow old craft and they stuck close to the coast where the ships were the thickest. This made it easy for the British armed motor-boat patrols to hunt them out and send them to the bottom. It was soon seen that larger and faster patrol boats carrying heavier guns were needed to keep up with the newer and faster U-boats that were sent to take the place of those the British sunk and so speedy 80 foot boats were built specially for patrolling.
“By the time we got into the war the U-boats were so big and fast that to catch them we had to have regular torpedo boats, except they are without torpedoes, built to run them down and this is exactly what this chaser we are now on is. With our chaser we can go twice as fast as any U-boat the Germans ever sent out and I’m telling you, matey, that if I ever spot a U-boat coming to the top and she is inside the range of this Hotchkiss her crew might just as well kiss the Kaiser good-night.”
The way the submarine chasers work is like this: A base is set up on shore close to that part of the coast waters, or zone as it is called, that a squadron, which is formed of a dozen chasers has to patrol. The shore base is fitted up with living quarters for the crews of the chasers, besides reserve crews who may be needed in an emergency, and there are also artificers, that is mechanics, carpenters, painters, etc., who stayed on shore so that when we were relieved from duty and came in, our boats were looked after as carefully and overhauled as thoroughly as a millionaire’s automobile.
The base also has a wireless station and any chaser can get in touch with it should occasion arise for her to do so. Each base also has one or more destroyers which carry heavier guns and these are stationed near by so that should the enemy loom up and prove too much for the guns of our chasers the larger boats can be signaled to help.
When a squadron of chasers leaves its base for the zone it is to patrol it is split up into two divisions of six boats each and a division officer is in charge of each one. Each chaser is given a certain area to patrol and she works with all the other chasers in her squadron, the shore station and ships at sea. If a U-boat has been sighted at sea, the ship who has picked her up immediately sends a wireless message to the base which in turn informs the commander of the squadron.
Should a U-boat venture into one of our zones the chasers get as busy as hornets and scout around until she either slips away or comes to the top to enable her commander to take a look around through his periscope to see if there is a ship in sight worth using a torpedo on.
Besides the regular wireless set each submarine chaser is fitted with a sound conduction signalling system and this is used to detect the presence of a U-boat when it is submerged and cannot be seen, though to do this the enemy boat must be near-by. This conduction scheme is very simple and you’ll get me fine as I explain it.
