Fortunately the entrance to the sheltered waterway was broad, and almost before it could be realised the sea grew calm. Although the wind still shrieked and moaned, the waves rose barely three feet high. Great cliffs, invisible in the darkness and driving sleet, protected the strait, and as the vessel picked her way to a safe anchorage closer under the lee of the land the wind lost its giant strength and the howling receded into the upper air.
Throughout the night the comparatively small warship rode safely at anchor, innocent of what was taking place out in the blackness and the storm. When morning broke the gale had lost some of its force, and streams of pale watery sunlight shone between the low-flying clouds on to a boisterous sea.

Running before the wind and sea the German raider Frederick, carefully disguised and loaded with several hundred mines, approached the British coast. The gale was increasing in force as darkness closed down, and heavy showers of sleet shielded her from the view of any passing craft. The weather was ideal for her dark purpose, which was to lay a mine-field over a stretch of sea where it was thought the Anglo-American trade routes converged.
For the first few days out from Wilhelmshaven the weather had been misty with heavy snowfalls, conditions enabling the mine-layer (and afterwards raider) to run the blockade and elude the network of patrols, not, however, without some very close shaves. On one occasion a large auxiliary cruiser passed in a snow squall, and during subsequent movements the raider found herself in the midst of a British fishing fleet, but passed unrecognised in the darkness. And now that she was approaching the British coast, and the scene of actual operations, the barometer again obliged by falling rapidly.
It was a wild night and very dark when the first mine splashed overboard. A snowstorm set in, and as the work proceeded heavy seas broke over the vessel, smothering her with spray, but she was comparatively a large ship, built for ocean trade. Although the darkness and the snow were conditions favourable to the laying of mines in secret, and without their aid the danger of discovery would have been great, the rising gale and the heavy seas rendered the work both difficult and dangerous, notwithstanding that these deadly weapons were so arranged as to go automatically overboard.
Before the last of her cargo had been consigned to the deep it was blowing great guns, and one sea after another was breaking over the ship. Although sheltered waters lay less than fifty miles distant, to proceed there would mean certain discovery and destruction, so all through that wild night, and for many hours afterwards, the raider sought by every means in her power to battle seawards, away from the coast and danger, heading into the teeth of the gale and out on to the broad bosom of the North Atlantic, all unknowing that but for the severity of the storm she must have been observed, probably in the very act of laying the mine-field, by the small warship riding out the north-wester in the more sheltered waters close inshore.
It is interesting to note that it was on this mine-field a few days later that one of the largest transatlantic liners was sunk.
