Feeling fairly secure, the salvors, according to an unofficial report, determined to get on with their job. A diver donned his dress, his helmet was screwed on, and the air-pumps began to heave as he dropped down to resume operations. He had been down but a short time when he felt himself plucked off his feet by a mighty pull on his life-line and air-pipe. He struggled to right himself, but it was quite useless. An irresistible force dragged him upwards; then he felt himself being drawn through the sea like a salmon at the end of a line. Something was running away with him. It was an awful experience. He wondered what had happened and how it would end. His senses began to reel; he found a difficulty in breathing. Somehow he managed to keep his head and act as the emergency demanded, closing the valve by which the air escaped from his helmet. A minute later he broke the surface. He could hear the seas slapping the top of his helmet as he was dragged along at a smart pace. His heart pounded, a terrible humming droned in his ears, but he strove hard to retain his senses. “What’s up?” he thought. “What on earth’s happening?” He had no chance of finding out. He was prisoner in a metal helmet and a rubber suit. He knew he was at the surface, because of the light that filtered through the glass of his helmet and the seas that swished against the copper. As he was dragged along, he had a tendency to spin at the end of his line, which gave him a dreadful sensation. In a dazed sort of way the diver was wondering how long the ordeal would last, when he suddenly felt himself plucked clear of the water. The next thing he remembers is something scorching his throat and the cool air playing about his head. He looked round and found he was lying on the deck of the salvage vessel, and he thanked his lucky star that all was well. Then he was placed in the recompression chamber aboard, so that the dangers of being dragged hastily from such a depth might be avoided, and the risk of bubbles of nitrogen forming in the blood averted. The air-pumps were set going to raise the pressure of the air in the steel chamber to the same pressure as that at which the diver had been working, and gradually the pressure was reduced until it was the normal atmospheric pressure and the diver was able to be taken out. While he was on the bottom, a German submarine had stealthily approached the salvage vessel. Suddenly it started to attack, and the salvage steamer had to cut and run for it, dragging the unfortunate diver in its wake. The attack was so unexpected that there was no time to pull up the diver in accordance with the rules. To pull him up in the ordinary way would, as a matter of fact, have taken half an hour. There was no alternative but to tow him along willy-nilly and haul him aboard as they fled. The experience might easily have cost the diver his life, but the recompression chamber fortunately saved him from any ill effects.
