The first I managed to reach had a defective valve on the oxygen bottle and I could not move it. The second was in working order and I put this over the head of one of the older ratings who was panicking and in tears due to the pressure effect on his eyes. The pressure in the boat at the time was immense and the chlorine content in the air considerable. The water all round us must have been full of oil fuel as we were all drenched with it, although I did not notice it at the time. The air could be heard to be escaping through the hull forward and the water was still rising fast.
