According to Herr Schmidt, the submarines work in groups of four. Because of the limited capacity of the boats for carrying provisions, supplies and fuel, it is necessary for them to have supply bases, to which they can return and secure torpedoes. In operation each group consists of four submarines, traveling along in a diamond-shaped formation, one in front, one on either flank and one in rear. Eight miles separate the boats. The leading submarine carries the extra gasoline and supplies and acts as a scoutship; she sights a vessel, reports its speed and direction and then submerges—her task is done.

The two torpedo carriers on either flank immediately change their courses so as to converge on the prey, and they arrive one on either side of her—they get her in between them. The boat in the rear keeps them informed as to the doomed ship's progress, and submerges at the last moment. She carries the extra crews for the fighting pair. The U-boats are fairly well protected against the onslaught of the light torpedo-boat destroyers and chasers, because the decks are protected by several feet of water at almost all times, while the commanding tower is covered with from two to three inches of the best steel armor plate.

It is related that at the outset of the U-boat menace, England ordered its commanding officers to ram the U-boats on sight. The length to which the Germans will go in an effort to win is illustrated by the fact that, in consequence of this order, a Von Tirpitz council presented this answer: Attacking submarines were equipped with explosive mines containing 300 to 400 pounds of nitroglycerin or guncotton. To the top of this mine was fastened a fake periscope. This devilish device was attached to the submarine by a light cable, and towed along the surface of the water 1000 feet or more behind the submarine. The result that would follow any attempt on the part of a commander to run down one of these decoys is readily imagined.
