“We are still afloat, glory be, and the engines are turnin’ over,” cried O’Shea.

He spun the wheel hard over to pass out to sea between the headlands, and steered where he thought deep water ought to be. The gun-boat had not opened fire, and he began to hope that he might win the freedom of the sea. Nor was the hostile vessel making any effort to follow him, and instead of blazing his trail with her search-light it had been turned skyward to flash signals for assistance against the clouds.

“I jolted the ambition out of her,” joyfully exclaimed O’Shea. “I would not like to look at my poor old hooker, but she must be an awful hash on deck——”

The Fearless suddenly yawed to starboard and took the bit in her teeth. The skipper tried to fetch her back on her course, but she failed to respond to the wheel. He instantly knew that a rudder chain had parted. He yelled down the tube to Johnny Kent to reverse his engines. The masterless tug was heading out of the channel and the incoming tide caught her bow and swung her away from the seaward passage, over toward the nearest headland and its submerged reef.

The Fearless felt the powerful backward drag of her screw, but not in time. The disabled steering-gear wrought the mischief before the emergency tiller could be manned or an anchor dropped to hold her in the channel. Her keel scraped along the coral bottom and the hull trembled to the shock of stranding. The Fearless was hard and fast aground and the tide lacked three hours of the flood.

Finding it useless to try to work her off, Captain O’Shea had the engines stopped. The plight was soon discovered by the gun-boat, which brought her search-light to bear on the tug. The Spanish commander laughed, no doubt, when he perceived that he could train his remaining guns and smash the Fearless to pieces at his leisure. It was point-blank range at a conspicuous target, and the tables had been turned.

Captain O’Shea comprehended the fate that was about to overtake his helpless ship. His boats had been cut adrift and there was no means of conveying his people to the shore. They could only swim for it and try to find footing on the reef.

“’Tis no use showing a white flag and offering to surrender,” he said to himself while the sweat ran down his face. “We fired on them and we rammed their ship.”

There was a life-raft on the deck-house roof, and he was about to order it shoved overside in order to send Nora Forbes and Miss Hollister ashore in charge of Van Steen and the mate. It was a forlorn hope, because the gun-boat would most likely fire at anything seen afloat. Just then Jack Gorham climbed to the bridge and respectfully saluted the captain.

“We are up against it, Jack,” said O’Shea. “The Spaniard yonder is taking his time. He will anchor bow and stern and then shoot us to splinters. I will be grateful if ye will lend the mate and young Van Steen a hand with the ladies. If ye can fetch the beach, take to the woods and try to find the camp of General Gomez.”
