Narrative of the Voyages and Services of the Nemesis from 1840 to 1843. Bernard William Dallas
no less than two-fifths of the entire circumference of the wheel. This large mass of iron could not have weighed less than fifteen to sixteen cwt.
On the following day, the 18th, the weather moderated considerably, and the vessel proceeded, with the help of one wheel only, at the rate of about four knots an hour. In the meantime, every possible effort was used to get the broken wheel repaired; and, in the short space of three days after the accident, the broken portion was got over the vessel's side with extraordinary labour, and was ultimately secured by bolts in its original place.
On the 20th, she passed within forty miles of Port Natal, (become so famous as the place the eminent Dutch farmers, from the Cape Colony, have attempted to make independent.) But there was little chance of being able to make the necessary repairs in such a place.
The dangerous condition of the vessel, after the iron plates on both sides had begun to open, could be concealed from none on board; but, as long as the weather was moderate, there appeared little doubt of her being able to reach Delagoa Bay without very great risk of foundering. On the following day, however, the 21st, the wind again began to freshen from the north-east, an unusual quarter at that time of the year. Again the mighty sea arose, and damped the reviving hopes of all, and the heavy cross swell could be looked on only with deep alarm.
Gradually, the opening in the ship's sides, which hitherto had been sufficiently limited to cause her to take in but little water, began to extend itself in an alarming manner. Indeed, it was impossible to guess where it would stop, or how any efficient means could be adopted to check it. Both sides were so bad that it was difficult to say which was worst. The vessel was evidently working amidships, as it is called; or, in other words, it had not only opened up and down, but was moving in and out from side to side. Moreover, the weather threatened to become rather worse than better; and, to add to the difficulty, the furnace of the larboard boiler was now found to be likewise injured, and, in fact, could scarcely be used at all. Thus it became more and more uncertain whether the engines could be kept working, so as to pump the water out of the hold; to say nothing of urging the vessel along.
Temporary expedients were at once to be resorted to; repairs were wanted at various parts at the same time, and every hand on board was now to be occupied day and night in contriving means to keep the vessel afloat. The heavy sea which, since the change of wind, had met the full current, and rolled heavily behind the vessel, threatened to break over her every instant. To provide as well as possible against this danger, four breadths of stout plank were secured, as strongly as possible, over the stern and along the quarters, in order to keep the sea out, or at all events to break its force. So heavy was the sea, that at this time the main rudder was sometimes completely out of water, and at the same moment the jib-boom was under it.
In the midst of this, with the hope of relieving the strain, by diminishing the top weight at the extremities, the aftermost or large stern gun was with great labour dismounted from its pivot-carriage, and safely deposited in one of the after coal-bunkers; and the bower anchors, which had already been brought inboard, were now dragged further amidships. This eased the ship a little. But gradually as the day advanced, the wind increased, and hourly the sea became more dangerous.
An attempt was, however, made on the 22nd to effect a temporary repair to the ship's sides, which were straining very much. For this purpose, two or three rivets were cut out on each side of the crack in the plates, and a portion of a new iron plate was with difficulty fixed on the outside, upon the worst part, and bolted through into a piece of stout oak plank, placed across it on the inside. The openings had by this time extended downwards more than three feet and a half on both sides of the vessel.
They were, at this time, at no great distance from Cape Vidal; but a tremendous current was setting to the south-west, at the rate of more than fifty miles a day, and helped to throw up a very heavy, dangerous sea. At length the morning dawned once more, and, as the day advanced, the north-east gale had moderated; and gradually it declined, until, in the afternoon, the wind changed round towards the south-east. The repairs to the damaged wheel were by this time completed, and although the injury to the ship's sides was hourly increasing, the hopes of all on board redoubled as they saw the double power of both wheels once more at work. But Delagoa Bay, for which they struggled still so hard, was not less than two hundred miles distant. As night closed in again, the angry wind began to howl, and burst upon the fated bark in heavy gusts and squalls. And all around was dark and solemn, as the fate which seemed again to threaten misery and destruction.
The only sail she now carried was torn away in shreds, and the steam itself had little power to stand the fury of the winds and waves. At length it lulled: again she moved, and yet again the mighty storm increased, and with alternate hopes and fears the morning's dawn was looked for. She heaved and strained most fearfully, the leaks increased, the openings spread, and yet she floated. 'Twas hoped that, as the day advanced, the storm would yield; but hour after hour, as it passed, had brought no sign of change or promise of amendment. Their danger was at this time imminent; but it became so evident to all that the only chance of safety lay in using unremitting exertions, and labouring day and night with hearty good-will, that their very efforts produced confidence, which, in its turn, redoubled all their strength. Nevertheless, it seemed as if new dangers were constantly in store.
The leaks continued to increase, her sides strained and opened fearfully, and the apertures had by this time extended upwards completely to the deck, and downwards far below the water-line. As the vessel heaved and rolled from side to side, the broken edges of the iron plates sometimes opened to the extent of an inch, while their lateral motion, as the vessel worked, in the part that had bulged, was frequently not less than five inches. As the storm increased, it was found that in the short space of two and a half hours, and in spite of every exertion to strengthen the part, the openings on both sides had further increased in length no less than eighteen inches.
The motion of the vessel, in such a pitching cross sea, was very quick; and every time the sides opened, the rush of wind and water through them was terrific. Luckily, the engines were still able to work, and continued to pump the water out very fast, although the openings were actually close to the engine-room itself. But the dangerous state of the vessel was appalling, not only from the fear of her separating amidships, but from the chance of the bilge-pumps becoming choked, or the fires being put out by the rush of water.
The struggle was evidently to be one for life or death. She groaned and worked tremendously, and reports were brought in quick succession from different parts of the vessel, that she was fast breaking up in pieces.
In this dilemma, it was still necessary to inspire the drooping spirits of the men with some new exertion. The captain tried to smile, and, by a cool, collected manner, sought to awaken hope which in secret he himself could scarcely feel. "You may smile, sir," said one of the sturdiest of the men, a hardy boiler-maker by trade, "but you don't know the nature of iron; how should you!" (as if in pity of his ignorance,) and then added, as if for comfort, "Ah, sir, when once it works and cracks, as our sides are doing now, it's sure to go on; nothing can stop it."
However, it was evident that talking about it would not mend the matter, and all that could be said was, "The greater our danger, the more must our exertions be increased to counteract it." And increased they were. Every officer and man set-to again in earnest, to try to keep the ship together. One party was employed to nail down thick planks and spars upon the deck, fore and aft, over the broken part of the ship; others were busy bolting the ends of them into the sponson-beams, between the paddle-boxes; while another party, engineers and firemen, were busy strengthening the ship's sides below.
To understand this latter part of the condition of affairs, it must be explained that, what in a wooden ship would be called the ribs, are, in an iron one, called the "angle-irons." They are, in fact, strong angular bars, extending up and down the ship's sides like ribs, having a flat surface, to which the plates of iron are bolted. These angle-irons, or ribs, are seventeen inches distant from each other, and at about the centre, between two of them, the crack had taken place in the plates of iron. The accident had occurred precisely in the weakest part of the vessel, amidships; and it would seem probable that, as there was a heavy cross sea in the Mozambique Channel when the misfortune happened, the head of the vessel was held firm in the hollow of one sea at the moment the top of another sea struck her heavily on the quarter.
