After four days' calm sailing a strong north wind arose, which drove us at uncommon speed in the right direction. We began to think ourselves nearly at the end of our journey when, on 6th August, the wind changed, and the storm began to rage with unheard-of violence. On the 7th, a Wednesday, at half-past two in the afternoon, we thought ourselves in imminent danger of death. It was not the terrible force with which the vessel was hurled up and down, entirely at the mercy of this sea monster, which appeared now as a fathomless abyss, now as a steep mountain peak, that filled me with mortal dread; my premonition of some terrible crisis was aroused by the despondency of the crew, whose malignant glances seemed superstitiously to point to us as the cause of the threatening disaster. Ignorant of the trifling occasion for the secrecy of our journey, the thought may have occurred to them that our need of escape had arisen from suspicious or even criminal circumstances. The captain himself seemed, in his extreme distress, to regret having taken us on board; for we had evidently brought him ill-luck on this familiar passage-usually a rapid and uncomplicated one, especially in summer. At this particular moment there raged, beside the tempest on the water, a furious thunderstorm overhead, and Minna expressed the fervent wish to be struck by lightning with me rather than to sink, living, into the fearful flood. She even begged me to bind her to me, so that we might not be parted as we sank. Yet another night was spent amid these incessant terrors, which only our extreme exhaustion helped to mitigate.
The following day the storm had subsided; the wind remained unfavourable, but was mild. The captain now tried to find our bearings by means of his astronomical instruments. He complained of the sky, which had been overcast so many days, swore that he would give much for a single glimpse of the sun or the stars, and did not conceal the uneasiness he felt at not being able to indicate our whereabouts with certainty. He consoled himself, however, by following a ship which was sailing some knots ahead in the same direction, and whose movements he observed closely through the telescope. Suddenly he sprang up in great alarm, and gave a vehement order to change our course. He had seen the ship in front go aground on a sand-bank, from which, he asserted, she could not extricate herself; for he now realised that we were near the most dangerous part of the belt of sand-banks bordering the Dutch coast for a considerable distance. By dint of very skilful sailing, we were enabled to keep the opposite course towards the English coast, which we in fact sighted on the evening of 9th August, in the neighbourhood of Southwold. I felt new life come into me when I saw in the far distance the English pilots racing for our ship. As competition is free among pilots on the English coast, they come out as far as possible to meet incoming vessels, even when the risks are very great.
The winner in our case was a powerful grey-haired man, who, after much vain battling with the seething waves, which tossed his light boat away from our ship at each attempt, at last succeeded in boarding the Thetis. (Our poor, hardly-used boat still bore the name, although the wooden figure-head of our patron nymph had been hurled into the sea during our first storm in the Cattegat- an ill-omened incident in the eyes of the crew.) We were filled with pious gratitude when this quiet English sailor, whose hands were torn and bleeding from his repeated efforts to catch the rope thrown to him on his approach, took over the rudder. His whole personality impressed us most agreeably, and he seemed to us the absolute guarantee of a speedy deliverance from our terrible afflictions. We rejoiced too soon, however, for we still had before us the perilous passage through the sand-banks off the English coast, where, as I was assured, nearly four hundred ships are wrecked on an average every year. We were fully twenty-four hours (from the evening of the 10th to the 11th of August) amid these sandbanks, fighting a westerly gale, which hindered our progress so seriously that we only reached the mouth of the Thames on the evening of the 12th of August. My wife had, up to that point, been so nervously affected by the innumerable danger signals, consisting chiefly of small guardships painted bright red and provided with bells on account of the fog, that she could not close her eyes, day or night, for the excitement of watching for them and pointing them out to the sailors. I, on the contrary, found these heralds of human proximity and deliverance so consoling that, despite Minna's reproaches, I indulged in a long refreshing sleep. Now that we were anchored in the mouth of the Thames, waiting for daybreak, I found myself in the best of spirits; I dressed, washed, and even shaved myself up on deck near the mast, while Minna and the whole exhausted crew were wrapped in deep slumber. And with deepening interest I watched the growing signs of life in this famous estuary. Our desire for a complete release from our detested confinement led us, after we had sailed a little way up, to hasten our arrival in London by going on board a passing steamer at Gravesend. As we neared the capital, our astonishment steadily increased at the number of ships of all sorts that filled the river, the houses, the streets, the famous docks, and other maritime constructions which lined the banks. When at last we reached London Bridge, this incredibly crowded centre of the greatest city in the world, and set foot on land after our terrible three weeks' voyage, a pleasurable sensation of giddiness overcame us as our legs carried us staggering through the deafening uproar. Robber seemed to be similarly affected, for he whisked round the corners like a mad thing, and threatened to get lost every other minute. But we soon sought safety in a cab, which took us, on our captain's recommendation, to the Horseshoe Tavern, near the Tower, and here we had to make our plans for the conquest of this giant metropolis.
