He managed to stagger inside the citadel just as the Huascar let fly with one of her 40-pounder guns, the shell from which struck full upon the very spot on the deck where he had been standing ten seconds previously, ripping a huge hole in the iron sheathing with which it was covered, and then exploding right over the engine-room hatch, which luckily was protected by a bomb-proof grating.

When Jim had at length cleared his eyes of dust and powder he delivered his message to the captain and was about to leave, but Condell requested him to remain, saying that he might want to make use of him. Montt was in the conning-tower, carrying out Condell’s orders as to the working of the engines, while the skipper himself watched carefully through the narrow observation-slit in the citadel, waiting for the moment when he might begin to open an effectual fire upon the enemy.

At length the moment arrived. The Covadonga had come up level with the Peruvian monitor, and the Union, being obliged to circle to seaward as she found herself in shoal water, was about three-quarters of a mile astern, although still firing incessantly. Condell gave one last look round and then shouted “Fire!” through the voice-tube which led to the gunboat’s little turret. Immediately there came a deafening roar and a tremendous concussion, as the two 70-pounders hurled forth their shells at the Huascar, and a dense cloud of white smoke drifted down upon the conning-tower, filling it with acrid fumes and momentarily blotting out the view.

When it cleared away it was seen that it had been a most lucky discharge, for one shell had struck full upon the monitor’s military mast, causing it to fall lengthwise along the ship, partly wrecking the funnel and a number of ventilators, while the other had apparently penetrated an open gun-port and thus reached some part of the ship’s boiler-room, for columns of steam were seen issuing from every available opening on the monitor’s midship section.

“Load again, men; load again!” cried Douglas, quite forgetting himself in the excitement of the moment.

“Another discharge like that, and we shall have the fellow completely crippled. Hurrah for the gallant little Covadonga!”

He was recalled to his senses by a short, sharp laugh from Condell, who remarked, with a grim smile: “Surely, Señor Douglas, you are not going to take away the command of my ship from me, are you?”

Jim, of course, promptly apologised, explaining that it was owing to the excitement that he had forgotten himself, but Condell told him to think no more of it, as it was the sort of spirit that he liked to see a young man display. There was little time for conversation, however, for the Huascar, as though in revenge for the damage inflicted by her puny enemy, again discharged her whole broadside—or at least so much of it as was still capable of being fired; and the marksmanship was so excellent that every missile again struck the Covadonga, while at the same moment the Union again started firing with her bow-guns, and a 100-pounder shell struck the gunboat full upon the stern, blowing a huge hole in it, killing four men, and shooting away the ensign-staff and flag.

When the smoke cleared away Douglas saw that their flag was gone, and at the same time heard the sound of cheering coming across the water from the Huascar—the Peruvians were under the impression that the gunboat had struck! But they were soon to be undeceived, for Jim rushed out of the conning-tower and down below, presently reappearing with another ensign under his arm. He then ran aft and proceeded to fix the spare staff, under a perfect hail of rifle-bullets from the monitor and corvette, and, having done so, ran up the flag amid cheers from the Covadonga. Then he went forward once more to his place in the conning-tower, which he reached just as Condell gave orders for the battery of 70-pounders to be fired again.

“Bravely done, gallantly done, my young friend,” said the skipper, as Jim made his appearance; “I won’t forget that action of yours if we come through all right.”
