one in the afternoon
Even the after hatch , in spite of the protection afforded by the conning-tower and the raised coaming , was admitting water into the interior of the submarine . Cold , exhausted , and hungry , the lads were glad to be able to eat and drink , discard their wringing-wet garments , and turn in . Without waking they slept solidly for ten hours . It was one in the afternoon when they turned out . U75 was rounding Land 's End . She was submerged , steering a compass course , but frequently showing her periscope to ascertain her whereabouts . Already the Longships Lighthouse was broad on the port beam .
