I have said that the North Sea was my finishing school of seamanship before I launched myself on the wider oceans. Confined as it is in comparison with the vast stage of this water-girt globe, I did not know it in all its parts. My classroom was the region of the English East Coast which, in the year of Peace with Honour, had long forgotten the war episodes belonging to its maritime history. It was a peaceful coast, agricultural, industrial, the home of fishermen. At night the lights of its many towns played on the clouds, or in clear weather lay still, here and there, in brilliant pools above the ink-black outline of the shore. On many a night I have hauled at the braces under the very shadow of that coast, envying, as sailors will, the people ashore sleeping quietly in their beds within sound of the sea. I imagine that not one head on these envied pillows was made uneasy by the slightest premonition of the realities of naval war the short lifetime of one generation was to bring to their peaceful shores. Though far away from that region of kindly memories and traversing a part of the North Sea much less known to me, I was deeply conscious of the familiarity of my surroundings. It was a cloudy, nasty day, and the aspects of nature don’t change, unless in the course of thousands of years--or, perhaps, centuries. The Phœnicians, its first discoverers, the Romans, the first imperial rulers of that sea, had experienced days like this, so different in the wintry quality of the light even on that July afternoon, from anything they had ever known in their native Mediterranean. For myself, a very late comer into that sea and its former pupil, I accorded amused recognition to the characteristic aspect so well remembered from my days of training. The same old thing. A grey-green expanse of smudgy waters grinning angrily at one with white foam-ridges, and over all a cheerless, unglowing canopy, apparently made of wet blotting-paper. From time to time a flurry of fine rain blew along like a puff of smoke across the dots of distant fishing boats, very few, very scattered, very solid and motionless against an ever dissolving, ever re-forming sky-line. Those flurries, and the steady rolling of the ship, accounted for the emptiness of the decks favouring my reminiscent mood.
