Not a ship within radius heard the call. Then cropped up another of those strange tricks of Fate. An American schoolboy, named Moore, keen on wireless long before the wireless boom set in, was experimenting with his home-made set when he picked up the call. Proudly he sent out this message of life and death on his own transmitter. The nearest naval depot picked it up and destroyers with special plant aboard were hurried at full speed to the rescue. Meanwhile the captain of the transport had managed with the greatest difficulty to get strong hawsers round the submarine, lashing them tightly to his transport in order to keep the stern of the submarine above water. Then his engineers after a deal of labour cut a small hole in the steel skin and began to pump fresh air in to the prisoners. This was the situation when the destroyers appeared on the scene. Immediately they fixed more hawsers round the submarine to prevent her from slipping to the bottom, and with the special appliances at their command they managed to cut through the rivets and force out one of the plates of the up-ended craft. One by one the twenty-seven men and their commanding officer scrambled through to the open air again, after being imprisoned for forty hours in that crazy submarine swinging about under the sea. Thus a telephone ringing in the open sea, where no telephone could possibly be expected, and a boy playing with his wireless set were instrumental in saving the lives of an entire crew after a most terrible experience. Not so fortunate were the crew of a British submarine which, like the K.13, met with a mishap that sent her plunging to the bottom. All were killed except one man, who with his own lips afterwards related how he had battled with death and won his way back to life after one of the most amazing adventures that have ever befallen man. He happened to be in the engine-room when he perceived the water pouring in through the conning tower in one mighty cascade. In a flash he realized that the boat was doomed. Rushing along the engine-room he shouted at the top of his voice to warn his comrades in the other parts of the ship. The sea swept into the engine-room after him. In a moment the floor was flooded. Fast as he moved, the water was faster. Before he could get out, he heard the sinister sound of the engine-room door slamming. He turned and thrust his shoulder against it. It would not budge. He was trapped in the engine-room of a sunken submarine! The rush of water had closed the bulkhead door, and the space beyond was completely flooded, making it impossible for the imprisoned man to move the door. Even if he had succeeded in opening the door, it would have been merely a matter of seconds before the hungry sea drowned him.
