The break-up of our floe came suddenly on Sunday, August 1, just one year after the Endurance left the South-West India Docks on the voyage to the Far South. The position was lat. 72° 26´ S., long. 48° 10´ W. The morning brought a moderate south-westerly gale with heavy snow, and at 8 a.m., after some warning movements of the ice, the floe cracked 40 yds. off the starboard bow. Two hours later the floe began to break up all round us under pressure and the ship listed over 10 degrees to starboard. I had the dogs and sledges brought aboard at once and the gangway hoisted. The animals behaved well. They came aboard eagerly as though realizing their danger, and were placed in their quarters on deck without a single fight occurring. The pressure was cracking the floe rapidly, rafting it close to the slip and forcing masses of ice beneath the keel. Presently the Endurance listed heavily to port against the gale, and at the same time was forced ahead, astern, and sideways several times by the grinding floes. She received one or two hard nips, but resisted them without as much as a creak. It looked at one stage as if the ship was to be made the plaything of successive floes, and I was relieved when she came to a standstill with a large piece of our old “dock” under the starboard bilge. I had the boats cleared away ready for lowering, got up some additional stores, and set a double watch. All hands were warned to stand by, get what sleep they could, and have their warmest clothing at hand. Around us lay the ruins of “Dog Town” amid the debris of pressure-ridges. Some of the little dwellings had been crushed flat beneath blocks of ice; others had been swallowed and pulverized when the ice opened beneath them and closed again. It was a sad sight, but my chief concern just then was the safety of the rudder, which was being attacked viciously by the ice. We managed to pole away a large lump that had become jammed between the rudder and the stern-post, but I could see that damage had been done, though a close examination was not possible that day.
After the ship had come to a standstill in her new position very heavy pressure was set up. Some of the trenails were started and beams buckled slightly under the terrific stresses. But the Endurance had been built to withstand the attacks of the ice, and she lifted bravely as the floes drove beneath her. The effects of the pressure around us were awe-inspiring. Mighty blocks of ice, gripped between meeting floes, rose slowly till they jumped like cherry-stones squeezed between thumb and finger. The pressure of millions of tons of moving ice was crushing and smashing inexorably. If the ship was once gripped firmly her fate would be sealed.
The gale from the south-west blew all night and moderated during the afternoon of the 2nd to a stiff breeze. The pressure had almost ceased. Apparently the gale had driven the southern pack down upon us, causing congestion in our area; the pressure had stopped when the whole of the pack got into motion. The gale had given us some northing, but it had dealt the Endurance what might prove to be a severe blow. The rudder had been driven hard over to starboard and the blade partially torn away from the rudder-head. Heavy masses of ice were still jammed against the stern, and it was impossible to ascertain the extent of the damage at that time. I felt that it would be impossible in any case to effect repairs in the moving pack. The ship lay steady all night, and the sole sign of continuing pressure was an occasional slight rumbling shock. We rigged shelters and kennels for the dogs inboard.
The weather on August 3 was overcast and misty. We had nine hours of twilight, with good light at noon. There was no land in sight for ten miles from the mast-head. The pack as far as the eye could reach was in a condition of chaos, much rafted and consolidated, with very large pressure-ridges in all directions. At 9 p.m. a rough altitude of Canopus gave the latitude as 71° 55´ 17´´ S. The drift, therefore, had been about 37 miles to the north in three days. Four of the poorest dogs were shot this day. They were suffering severely from worms, and we could not afford to keep sick dogs under the changed conditions. The sun showed through the clouds on the northern horizon for an hour on the 4th. There was no open water to be seen from aloft in any direction. We saw from the masthead to west-south-west an appearance of barrier, land, or a very long iceberg, about 20 odd miles away, but the horizon clouded over before we could determine its nature. We tried twice to make a sounding that day, but failed on each occasion. The Kelvin machine gave no bottom at the full length of the line, 370 fathoms. After much labour we made a hole in the ice near the stern-post large enough for the Lucas machine with a 32-lb. lead; but this appeared to be too light. The machine stopped at 452 fathoms, leaving us in doubt as to whether bottom had been reached. Then in heaving up we lost the lead, the thin wire cutting its way into the ice and snapping. All hands and the carpenter were busy this day making and placing kennels on the upper deck, and by nightfall all the dogs were comfortably housed, ready for any weather. The sun showed through the clouds above the northern horizon for nearly an hour.
The remaining days of August were comparatively uneventful. The ice around the ship froze firm again and little movement occurred in our neighbourhood. The training of the dogs, including the puppies, proceeded actively, and provided exercise as well as occupation. The drift to the north-west continued steadily. We had bad luck with soundings, the weather interfering at times and the gear breaking on several occasions, but a big increase in the depth showed that we had passed over the edge of the Weddell Sea plateau. A sounding of about 1700 fathoms on August 10 agreed fairly well with Filchner’s 1924 fathoms, 130 miles east of our then position. An observation at noon of the 8th had given us lat. 71° 23´ S., long. 49° 13´ W. Minus temperatures prevailed still, but the daylight was increasing. We captured a few emperor penguins which were making their way to the south-west. Ten penguins taken on the 19th were all in poor condition, and their stomachs contained nothing but stones and a few cuttle-fish beaks. A sounding on the 17th gave 1676 fathoms, 10 miles west of the charted position of Morell Land. No land could be seen from the mast-head, and I decided that Morell Land must be added to the long list of Antarctic islands and continental coasts that on close investigation have resolved themselves into icebergs. On clear days we could get an extended view in all directions from the mast-head, and the line of the pack was broken only by familiar bergs. About one hundred bergs were in view on a fine day, and they seemed practically the same as when they started their drift with us nearly seven months earlier. The scientists wished to inspect some of the neighbouring bergs at close quarters, but sledge travelling outside the well-trodden area immediately around the ship proved difficult and occasionally dangerous. On August 20, for example, Worsley, Hurley, and Greenstreet started off for the Rampart Berg and got on to a lead of young ice that undulated perilously beneath their feet. A quick turn saved them.
A wonderful mirage of the Fata Morgana type was visible on August 20. The day was clear and bright, with a blue sky overhead and some rime aloft.
“The distant pack is thrown up into towering barrier-like cliffs, which are reflected in blue lakes and lanes of water at their base. Great white and golden cities of Oriental appearance at close intervals along these clifftops indicate distant bergs, some not previously known to us. Floating above these are wavering violet and creamy lines of still more remote bergs and pack. The lines rise and fall, tremble, dissipate, and reappear in an endless transformation scene. The southern pack and bergs, catching the sun’s rays, are golden, but to the north the ice-masses are purple. Here the bergs assume changing forms, first a castle, then a balloon just clear of the horizon, that changes swiftly into an immense mushroom, a mosque, or a cathedral. The principal characteristic is the vertical lengthening of the object, a small pressure-ridge being given the appearance of a line of battlements or towering cliffs. The mirage is produced by refraction and is intensified by the columns of comparatively warm air rising from several cracks and leads that have opened eight to twenty miles away north and south.”
We noticed this day that a considerable change had taken place in our position relative to the Rampart Berg. It appeared that a big lead had opened and that there had been some differential movement of the pack. The opening movement might presage renewed pressure. A few hours later the dog teams, returning from exercise, crossed a narrow crack that had appeared ahead of the ship. This crack opened quickly to 60 ft. and would have given us trouble if the dogs had been left on the wrong side. It closed on the 25th and pressure followed in its neighbourhood.
On August 24 we were two miles north of the latitude of Morell’s farthest south, and over 10° of longitude, or more than 200 miles, west of his position. From the mast-head no land could be seen within twenty miles, and no land of over 500 ft. altitude could have escaped observation on our side of long. 52° W. A sounding of 1900 fathoms on August 25 was further evidence of the non-existence of New South Greenland. There was some movement of the ice near the ship during the concluding days of the month. All hands were called out in the night of August 26, sounds of pressure having been followed by the cracking of the ice alongside the ship, but the trouble did not develop immediately. Late on the night of the 31st the ice began to work ahead of the ship and along the port side. Creaking and groaning of timbers, accompanied by loud snapping sounds fore and aft, told their story of strain. The pressure continued during the following day, beams and deck planks occasionally buckling to the strain. The ponderous floes were grinding against each other under the influence of wind and current, and our ship seemed to occupy for the time being an undesirable position near the centre of the disturbance; but she resisted staunchly and showed no sign of water in the bilges, although she had not been pumped out for six months. The pack extended to the horizon in every direction. I calculated that we were 250 miles from the nearest known land to the westward, and more than 500 miles from the nearest outpost of civilization, Wilhelmina Bay. I hoped we would not have to undertake a march across the moving ice-fields. The Endurance we knew to be stout and true; but no ship ever built by man could live if taken fairly in the grip of the floes and prevented from rising to the surface of the grinding ice. These were anxious days. In the early morning of September 2 the ship jumped and shook to the accompaniment of cracks and groans, and some of the men who had been in the berths hurried on deck. The pressure eased a little later in the day, when the ice on the port side broke away from the ship to just abaft the main rigging. The Endurance was still held aft and at the rudder, and a large mass of ice could be seen adhering to the port bow, rising to within three feet of the surface. I wondered if this ice had got its grip by piercing the sheathing.
The ice did not trouble us again seriously until the end of September, though during the whole month the floes were seldom entirely without movement. The roar of pressure would come to us across the otherwise silent ice-fields, and bring with it a threat and a warning. Watching from the crow’s-nest, we could see sometimes the formation of pressure-ridges. The sunshine glittered on newly riven ice-surfaces as the masses of shattered floe rose and fell away from the line of pressure. The area of disturbance would advance towards us, recede, and advance again. The routine of work and play on the Endurance proceeded steadily. Our plans and preparations for any contingency that might arise during the approaching summer had been made, but there seemed always plenty to do in and about our prisoned ship. Runs with the dogs and vigorous games of hockey and football on the rough snow-covered floe kept all hands in good fettle. The record of one or two of these September days will indicate the nature of our life and our surroundings:
“September 4.—Temperature, —14.1° Fahr. Light easterly breeze, blue sky, and stratus clouds. During forenoon notice a distinct terra-cotta or biscuit colour in the stratus clouds to the north. This travelled from east to west and could conceivably have come from some of the Graham Land volcanoes, now about 300 miles distant to the north-west. The upper current of air probably would come from that direction. Heavy rime. Pack unbroken and unchanged as far as visible. No land for 22 miles. No animal life observed.”
“September 7.—Temperature, —10.8° Fahr. Moderate easterly to southerly winds, overcast and misty, with light snow till midnight, when weather cleared. Blue sky and fine clear weather to noon. Much rime aloft. Thick fresh snow on ship and floe that glistens brilliantly in the morning sunlight. Little clouds of faint violet-coloured mist rise from the lower and brinier portions of the pack, which stretches unbroken to the horizon. Very great refraction all round. A tabular berg about fifty feet high ten miles west is a good index of the amount of refraction. On ordinary days it shows from the mast-head, clear-cut against the sky; with much refraction, the pack beyond at the back of it lifts up into view; to-day a broad expanse of miles of pack is seen above it. Numerous other bergs generally seen in silhouette are, at first sight, lost, but after a closer scrutiny they appear as large lumps or dark masses well below the horizon. Refraction generally results in too big an altitude when observing the sun for position, but to-day, the horizon is thrown up so much that the altitude is about 12´ too small. No land visible for twenty miles. No animal life observed. Lower Clark’s tow-net with 566 fathoms of wire, and hoist it up at two and a half miles an hour by walking across the floe with the wire. Result rather meagre—jelly-fish and some fish larvae. Exercise dogs in sledge teams. The young dogs, under Crean’s care, pull as well, though not so strongly, as the best team in the pack. Hercules for the last fortnight or more has constituted himself leader of the orchestra. Two or three times in the twenty-four hours he starts a howl—a deep, melodious howl—and in about thirty seconds he has the whole pack in full song, the great deep, booming, harmonious song of the half-wolf pack.”
By the middle of September we were running short of fresh meat for the dogs. The seals and penguins seemed to have abandoned our neighbourhood altogether. Nearly five months had passed since we killed a seal, and penguins had been seen seldom. Clark, who was using his trawl as often as possible, reported that there was a marked absence of plankton in the sea, and we assumed that the seals and the penguins had gone in search of their accustomed food. The men got an emperor on the 23rd. The dogs, which were having their sledging exercise, became wildly excited when the penguin, which had risen in a crack, was driven ashore, and the best efforts of the drivers failed to save it alive. On the following day Wild, Hurley, Macklin, and McIlroy took their teams to the Stained Berg, about seven miles west of the ship, and on their way back got a female crab-eater, which they killed, skinned, and left to be picked up later. They ascended to the top of the berg, which lay in about lat. 69° 30´ S., long. 51° W., and from an elevation of 110 ft. could see no land. Samples of the discoloured ice from the berg proved to contain dust with black gritty particles or sand-grains. Another seal, a bull Weddell, was secured on the 26th. The return of seal-life was opportune, since we had nearly finished the winter supply of dog-biscuit and wished to be able to feed the dogs on meat. The seals meant a supply of blubber, moreover, to supplement our small remaining stock of coal when the time came to get up steam again. We initiated a daylight-saving system on this day by putting forward the clock one hour. “This is really pandering to the base but universal passion that men, and especially seafarers, have for getting up late, otherwise we would be honest and make our routine earlier instead of flogging the clock.”
During the concluding days of September the roar of the pressure grew louder, and I could see that the area of disturbance was rapidly approaching the ship. Stupendous forces were at work and the fields of firm ice around the Endurance were being diminished steadily. September 30 was a bad day. It began well, for we got two penguins and five seals during the morning. Three other seals were seen. But at 3 p.m. cracks that had opened during the night alongside the ship commenced to work in a lateral direction. The ship sustained terrific pressure on the port side forward, the heaviest shocks being under the forerigging. It was the worst squeeze we had experienced. The decks shuddered and jumped, beams arched, and stanchions buckled and shook. I ordered all hands to stand by in readiness for whatever emergency might arise. Even the dogs seemed to feel the tense anxiety of the moment. But the ship resisted valiantly, and just when it appeared that the limit of her strength was being reached the huge floe that was pressing down upon us cracked across and so gave relief.
“The behaviour of our ship in the ice has been magnificent,” wrote Worsley. “Since we have been beset her staunchness and endurance have been almost past belief again and again. She has been nipped with a million-ton pressure and risen nobly, falling clear of the water out on the ice. She has been thrown to and fro like a shuttlecock a dozen times. She has been strained, her beams arched upwards, by the fearful pressure; her very sides opened and closed again as she was actually bent and curved along her length, groaning like a living thing. It will be sad if such a brave little craft should be finally crushed in the remorseless, slowly strangling grip of the Weddell pack after ten months of the bravest and most gallant fight ever put up by a ship.”
The Endurance deserved all that could be said in praise of her. Shipwrights had never done sounder or better work; but how long could she continue the fight under such conditions? We were drifting into the congested area of the western Weddell Sea, the worst portion of the worst sea in the world, where the pack, forced on irresistibly by wind and current, impinges on the western shore and is driven up in huge corrugated ridges and chaotic fields of pressure. The vital question for us was whether or not the ice would open sufficiently to release us, or at least give us a chance of release, before the drift carried us into the most dangerous area. There was no answer to be got from the silent bergs and the grinding floes, and we faced the month of October with anxious hearts.
The leads in the pack appeared to have opened out a little on October 1, but not sufficiently to be workable even if we had been able to release the Endurance from the floe. The day was calm, cloudy and misty in the forenoon and clearer in the afternoon, when we observed well-defined parhelia. The ship was subjected to slight pressure at intervals. Two bull crab-eaters climbed on to the floe close to the ship and were shot by Wild. They were both big animals in prime condition, and I felt that there was no more need for anxiety as to the supply of fresh meat for the dogs. Seal-liver made a welcome change in our own menu. The two bulls were marked, like many of their kind, with long parallel scars about three inches apart, evidently the work of the killers. A bull we killed on the following day had four parallel scars, sixteen inches long, on each side of its body; they were fairly deep and one flipper had been nearly torn away. The creature must have escaped from the jaws of a killer by a very small margin. Evidently life beneath the pack is not always monotonous. We noticed that several of the bergs in the neighbourhood of the ship were changing their relative positions more than they had done for months past. The floes were moving.
Our position on Sunday, October 3, was lat. 69° 14´ S., long. 51° 8´ W. During the night the floe holding the ship aft cracked in several places, and this appeared to have eased the strain on the rudder. The forenoon was misty, with falls of snow, but the weather cleared later in the day and we could see that the pack was breaking. New leads had appeared, while several old leads had closed. Pressure-ridges had risen along some of the cracks. The thickness of the season’s ice, now about 230 days old, was 4 ft. 5 in. under 7 or 8 in. of snow. This ice had been slightly thicker in the early part of September, and I assumed that some melting had begun below. Clark had recorded plus temperatures at depths of 150 and 200 fathoms in the concluding days of September. The ice obviously had attained its maximum thickness by direct freezing, and the heavier older floes had been created by the consolidation of pressure-ice and the overlapping of floes under strain. The air temperatures were still low, —24.5° Fahr. being recorded on October 4.
The movement of the ice was increasing. Frost-smoke from opening cracks was showing in all directions during October 6. It had the appearance in one place of a great prairie fire, rising from the surface and getting higher as it drifted off before the wind in heavy, dark, rolling masses. At another point there was the appearance of a train running before the wind, the smoke rising from the locomotive straight upwards; and the smoke columns elsewhere gave the effect of warships steaming in line ahead. During the following day the leads and cracks opened to such an extent that if the Endurance could have been forced forward for thirty yards we could have proceeded for two or three miles; but the effort did not promise any really useful result. The conditions did not change materially during the rest of that week. The position on Sunday, October 10, was lat. 69° 21´ S., long. 50° 34´ W. A thaw made things uncomfortable for us that day. The temperature had risen from —10° Fahr. to +29.8° Fahr., the highest we had experienced since January, and the ship got dripping wet between decks. The upper deck was clear of ice and snow and the cabins became unpleasantly messy. The dogs, who hated wet, had a most unhappy air. Undoubtedly one grows to like familiar conditions. We had lived long in temperatures that would have seemed distressingly low in civilized life, and now we were made uncomfortable by a degree of warmth that would have left the unaccustomed human being still shivering. The thaw was an indication that winter was over, and we began preparations for reoccupying the cabins on the main deck. I had the shelter-house round the stern pulled down on the 11th and made other preparations for working the ship as soon as she got clear. The carpenter had built a wheel-house over the wheel aft as shelter in cold and heavy weather. The ice was still loosening and no land was visible for twenty miles.
The temperature remained relatively high for several days. All hands moved to their summer quarters in the upper cabins on the 12th, to the accompaniment of much noise and laughter. Spring was in the air, and if there were no green growing things to gladden our eyes, there were at least many seals, penguins, and even whales disporting themselves in the leads. The time for renewed action was coming, and though our situation was grave enough, we were facing the future hopefully. The dogs were kept in a state of uproar by the sight of so much game. They became almost frenzied when a solemn-looking emperor penguin inspected them gravely from some point of vantage on the floe and gave utterance to an apparently derisive “Knark!” At 7 p.m. on the 13th the ship broke free of the floe on which she had rested to starboard sufficiently to come upright. The rudder freed itself, but the propeller was found to be athwartship, having been forced into that position by the floe some time after August 1. The water was very clear and we could see the rudder, which appeared to have suffered only a slight twist to port at the water-line. It moved quite freely. The propeller, as far as we could see, was intact, but it could not be moved by the hand-gear, probably owing to a film of ice in the stern gland and sleeve. I did not think it advisable to attempt to deal with it at that stage. The ship had not been pumped for eight months, but there was no water and not much ice in the bilges. Meals were served again in the wardroom that day.
The south-westerly breeze freshened to a gale on the 14th, and the temperature fell from +31° Fahr. to —1° Fahr. At midnight the ship came free from the floe and drifted rapidly astern. Her head fell off before the wind until she lay nearly at right-angles across the narrow lead. This was a dangerous position for rudder and propeller. The spanker was set, but the weight of the wind on the ship gradually forced the floes open until the Endurance swung right round and drove 100 yds. along the lead. Then the ice closed and at 3 a.m. we were fast again. The wind died down during the day and the pack opened for five or six miles to the north. It was still loose on the following morning, and I had the boiler pumped up with the intention of attempting to clear the propeller; but one of the manholes developed a leak, the packing being perished by cold or loosened by contraction, and the boiler had to be emptied out again.
The pack was rather closer on Sunday the 17th. Top-sails and head-sails were set in the afternoon, and with a moderate north-easterly breeze we tried to force the ship ahead out of the lead; but she was held fast. Later that day heavy pressure developed. The two floes between which the Endurance was lying began to close and the ship was subjected to a series of tremendously heavy strains. In the engine-room, the weakest point, loud groans, crashes, and hammering sounds were heard. The iron plates on the floor buckled up and overrode with loud clangs. Meanwhile the floes were grinding off each other’s projecting points and throwing up pressure-ridges. The ship stood the strain well for nearly an hour and then, to my great relief, began to rise with heavy jerks and jars. She lifted ten inches forward and three feet four inches aft, at the same time heeling six degrees to port. The ice was getting below us and the immediate danger had passed. The position was lat. 69° 19´ S., long. 50° 40´ W.
The next attack of the ice came on the afternoon of October 18th. The two floes began to move laterally, exerting great pressure on the ship. Suddenly the floe on the port side cracked and huge pieces of ice shot up from under the port bilge. Within a few seconds the ship heeled over until she had a list of thirty degrees to port, being held under the starboard bilge by the opposing floe. The lee boats were now almost resting on the floe. The midship dog-kennels broke away and crashed down on to the lee kennels, and the howls and barks of the frightened dogs assisted to create a perfect pandemonium. Everything movable on deck and below fell to the lee side, and for a few minutes it looked as if the Endurance would be thrown upon her beam ends. Order was soon restored. I had all fires put out and battens nailed on the deck to give the dogs a foothold and enable people to get about. Then the crew lashed all the movable gear. If the ship had heeled any farther it would have been necessary to release the lee boats and pull them clear, and Worsley was watching to give the alarm. Hurley meanwhile descended to the floe and took some photographs of the ship in her unusual position. Dinner in the wardroom that evening was a curious affair. Most of the diners had to sit on the deck, their feet against battens and their plates on their knees. At 8 p.m. the floes opened, and within a few minutes the Endurance was nearly upright again. Orders were given for the ice to be chipped clear of the rudder. The men poled the blocks out of the way when they had been detached from the floe with the long ice-chisels, and we were able to haul the ship’s stern into a clear berth. Then the boiler was pumped up. This work was completed early in the morning of October 19, and during that day the engineer lit fires and got up steam very slowly, in order to economize fuel and avoid any strain on the chilled boilers by unequal heating. The crew cut up all loose lumber, boxes, etc., and put them in the bunkers for fuel. The day was overcast, with occasional snowfalls, the temperature +12° Fahr. The ice in our neighbourhood was quiet, but in the distance pressure was at work. The wind freshened in the evening, and we ran a wire-mooring astern. The barometer at 11 p.m. stood at 28.96, the lowest since the gales of July. An uproar among the dogs attracted attention late in the afternoon, and we found a 25-ft. whale cruising up and down in our pool. It pushed its head up once in characteristic killer fashion, but we judged from its small curved dorsal fin that it was a specimen of Balaenoptera acutorostrata, not Orca gladiator.
A strong south-westerly wind was blowing on October 20 and the pack was working. The Endurance was imprisoned securely in the pool, but our chance might come at any time. Watches were set so as to be ready for working ship. Wild and Hudson, Greenstreet and Cheetham, Worsley and Crean, took the deck watches, and the Chief Engineer and Second Engineer kept watch and watch with three of the A.B.’s for stokers. The staff and the forward hands, with the exception of the cook, the carpenter and his mate, were on “watch and watch”—that is, four hours on deck and four hours below, or off duty. The carpenter was busy making a light punt, which might prove useful in the navigation of lanes and channels. At 11 a.m. we gave the engines a gentle trial turn astern. Everything worked well after eight months of frozen inactivity, except that the bilge-pump and the discharge proved to be frozen up; they were cleared with some little difficulty. The engineer reported that to get steam he had used one ton of coal, with wood-ashes and blubber. The fires required to keep the boiler warm consumed one and a quarter to one and a half hundred-weight of coal per day. We had about fifty tons of coal remaining in the bunkers.
