His first attempt to remove the securings of the hatch was frustrated by the weight of the water on the upper surface of the submarine; this would be ultimately overcome by the air pressure inside, but not till the water had risen considerably. Every moment’s delay increased the gas and some faster means of flooding the compartment had to be devised. The man climbed down and tried various methods, groping about in the choking darkness, diving below the scummy surface of the slowly rising tide to feel for half-forgotten valves. In the course of this he came in contact with the switchboard of the dynamo and narrowly escaped electrocution. Shaken by the shock, and half suffocated by the gas, he eventually succeeded in admitting a quicker flow of water; the internal pressure lifted the hatch off its seating sufficiently to enable him to knock off the securings. The water still rose, but thinking that he now had sufficient pressure accumulated, he made his first bid for freedom. Three times he succeeded in raising the hatch, but not sufficiently to allow him to pass: each time the air escaped and each time the hatch fell again before he could get through. More pressure was needed, which meant that more water would have to be admitted from the fore-compartment, and with it unfortunately more gas. First of all, however, the hatch had to be secured again. The man dived to the bottom of the boat and found the securing clips, swam up with them and secured the hatch once more. Then he opened the deadlight between the two compartments a little way, increased the inrush of water, and climbing back on to the top of the engines knocked the bolts away. As he expected the hatch flew open, but the pressure was not now sufficient to blow him out. He started to climb out, when down came the hatch again, and fastened on his hand, crushing it beneath its weight. By dint of wedging his shoulder beneath the hatch he succeeded in finally releasing his hand and allowed the hatch to drop back into its place. Loss of consciousness, nerve, or hope would have sealed his doom any moment during the past two hours, but even in this bitter extremity his indomitable courage refused to be beaten. Gassed, electrocuted, maimed, cornered like a rat in a hole, he rallied all his faculties for a final desperate effort. Crawling down again, he swam to the deadlight and knocked off the nuts to admit the full rush of water. The compartment would now flood completely, but it was his last chance. He climbed back under the hatch and waited. The water rose until it reached the coaming of the hatch; with his final remnant of strength he forced up the hatch for the last time. The air leaped surface-wards, driven out by the water which impatiently invaded the last few feet it had striven for so long. With it, back through a depth of sixty feet, back to God’s sunlight and men’s voices and life, passed a Man. * * * * *
