The Orontabella's stern was now under water. She had a pronounced list to starboard. Dense volumes of smoke and steam, pouring from her funnels and hatchways, showed that the water had already invaded her boiler-room. Above the hiss of the scalding vapour and the rush of escaping air, could be heard the terrified neighing of a dozen or more wounded horses, for whom no escape was possible.
Clustering on the fo'c'sle were about twenty or thirty men, the officers and crew who had survived the explosion; for the death-roll, especially in the engine-room and stokehold, was very high, men being overwhelmed by the inrush of water before they could scramble up the steep ladder and through the narrow hatchway.
The waiting men showed no signs of panic. Those who could swim had not troubled to don their cork life-belts, but were calmly engaged in lashing their life-saving devices round the shoulders of their less fortunate comrades.
Ross ordered his men to back towards the foundering vessel. He realized that at any moment the transport might plunge suddenly, and the danger of being dragged down by the suction was a thing he had to avoid. There was also a risk of the boat being swamped by the men as they clambered on board.
"Jump!" he shouted. "Not too many at a time."
Three men accepted the invitation: two good swimmers and a non-swimmer. The former, grasping their struggling companion by the shoulders, struck out without much difficulty and reached Ross's boat, where they were quickly hauled into safety.
Setting the rescued men to take an oar each, for there were several to spare lying on the thwarts, Ross took the whaler closer in, since he had now more means of propulsion at his command.
Four more followed, and were picked up by Vernon's men. Meanwhile the bows of the Orontabella were rising high out of the water, as the stern sank correspondingly deeper, until those of the officers and crew who still remained on board had to cling desperately to the rails to prevent themselves slipping into the maelstrom that surged over the submerged part of the sinking ship.
Suddenly the vessel dived. Where a few seconds previously a towering mass of black and red plating rose high above the boats, there hung a cloud of smoke, steam, and spray, while all around the water was thrashed white with foam.
"Give way, men!" shouted Ross.
The rowers were too late. Before the boat could pull clear of the scene of disaster, a vicious, crested wave, so hollow that the lean quarters of the whaler were unable to rise to it, poured into the frail craft.
The next instant Ross and his crew were struggling in the confusion of the broiling sea.
Vernon, although farther from the spot, narrowly escaped the fate of his chum. It was surprising what a terrific commotion the Orontabella caused at the last. For some minutes he could see nothing beyond the tips of the blades of the oars. Everything else was enveloped in smoke, steam, and spray.
Gradually the waves subsided and the wind dispersed the pall of vapour. The sea was dotted with the heads of swimmers. Ross's boat, with her stem and stern-posts just visible above the surface, was waterlogged, yet retained sufficient buoyancy to support half a dozen men.
Here, indeed, was a pretty pickle. At the very most, Vernon's boat would hold fifteen or sixteen men. The Capella was almost out of sight. The whole attention of her officers and crew would be centred upon the U-boat. So long as there was any indication of the latter's whereabouts, the patrol-vessel would cling tenaciously to her quest.
There was very little left floating from the sunken ship. A few gratings, handspikes, a couple of breakers, and fragments of the shattered boats, but nothing substantial enough to support a man above water; and in mid-Channel, although it was only September, the sea was too cold to enable the swimmers to keep afloat very long without almost certain danger of cramp.
Vernon looked around for his chum. He saw him sharing an oar with one of the crew.
"Come on, my lads!" shouted Ross encouragingly. "We'll hike her up. Half a dozen of you who have life-belts come round this side, and when I say 'All together!' lift for all you're worth."
The men obeyed as quickly as they could in the circumstances. Finding that they could easily keep afloat, the non-swimmers had regained their confidence. Piloted by those who could swim, the men ranged themselves along one gunwale of the waterlogged whaler.
"All ready?" asked Ross, whose knowledge of how to empty a waterlogged Canadian canoe prompted him to try a large, heavy boat. "Together!"
Up rose the boat's gunwale as high as the men's arms could reach, but with a dull swish the whaler resumed its former position. In lifting one side the other had dropped deeply beneath the surface, and the attempt to shake out the water had ended in failure.
"Now then," ordered Vernon, taking his turn to direct operations. "All swimmers get overboard for a few minutes. Those with life-belts get on board, and take off your belts."
In five minutes a dozen cork life-belts were available. Manoeuvring his boat alongside the waterlogged whaler, Vernon gave directions for the belts to be lashed underneath the thwarts, so that they were completely submerged. Then taking the whaler's painter he hove taut until, added to the lifting powers of the cork and the upward strain on the ropes, the gunwale rose a good three inches above the water.
This done, one of the Capella's men, armed with a baler, began throwing out the water from the whaler. In another five minutes the boat showed sufficient buoyancy to allow two more hands to clamber on board. They, too, baled vigorously, with the result that once more the whaler was free from water.
Between the two boats, all the survivors of the Orontabella were easily accommodated; but when at length the midshipmen looked for the Capella, the patrol-boat was nowhere to be seen.
CHAPTER XXI. Adrift in the Channel
"She'll be back for us soon," declared Vernon optimistically, addressing his chum, for the two boats were within twenty feet of each other. "Can you see any signs of her now?"
Ross stood upright in the stern-sheets and, shading his eyes with his hand, gave a careful look in the direction where the Capella was supposed to be.
"No," he answered. "And I cannot see any signs of the other vessels we saw some time ago. We'd better let the men rest on their oars."
Unknown to the two midshipmen, they had for the last hour and a half been in the grip of the strong west-going tide that surges along the French coast. In that interval they had been carried out of the course of the vessels they had sighted, and were some four or six miles from the spot where the Orontabella had sunk.
Another hour passed. The men who had been in the water took the opportunity of drying their clothing in the hot sunshine. They treated their misfortune lightly, making very little reference to the loss of their vessel. One would have thought that being torpedoed was almost an everyday occurrence.
As the minutes slipped by, it began to occur to Ross and his chum that the Capella had missed them entirely. In another few hours night would be coming on, and the prospect of spending ten hours of darkness in a couple of open boats in mid-Channel was not at all alluring.
Each boat was equipped with compass, lead-line, signal-book, lamp, box of biscuits, and beaker of water. None of these articles belonging to Ross's boat had suffered, in spite of their being immersed, except the lamp, for the provisions were in watertight boxes. Masts and sails were not in the boats, having been left on board the Capella when the rescuers put off hurriedly on their errand of mercy.
