Now the blows that ought to have been described as staggering redoubled as shell after shell struck the cruiser's armoured plating, while to the louder detonations of the 6in. and the 4.7in. guns was added the sharp bark of the 6- and 12-pounders. The air that eddied furiously through the apertures in the conning-tower was foul with the acrid fumes, while fragments of glowering metal even found their way into the steel shell. Suddenly one of the quartermasters who was standing in reserve at the after end of the tower spun round, and blindly fumbling with his outstretched hands, sank lifeless to the deck. As he did so he grasped one of the levers, thrusting it downward as he fell. Instinctively Gerald turned, disengaged the man's grasp, and replaced the lever; but the mischief was but partly averted. The funnel, windscreens, and the sliding hatches that concealed the boats were beginning to raise themselves above the deck, and, caught by the withering blast, the thin steel plating was riddled like paper. Then did Captain Brookes shift his position; but it was not on account of the damage caused by the lifeless quartermaster. The _Olive Branch_ was drawing within the danger zone of her own Z-rays. Separating the pointers and springing back to his post, the captain put the helm hard over. Round swung the _Olive Branch_, listing dangerously outwards as he described a short curve with undiminished speed; and at that moment the British cruisers, freed from the irritating influence of the Z-rays, threw their searchlights upon the daring fugitive. Having gained an offing, Captain Brookes shaped a course to the south'ard, thus presenting the whole broadside as a tempting target to the _Niobe_. Eight of her 6in. guns thundered on the irresistible _Olive Branch_ with but little effect, though she reeled as the missiles smashed against her lofty sides. A round from one of the latter's weapons could pulverise the 11,000 tons unarmoured cruiser, yet even in the heat of this one-sided encounter Captain Brookes kept his word. Then the running fight soon became a hopeless stern-chase, and fifteen minutes after leaving Talcahuano Harbour the report of the last gun died away in long-drawn reverberations like the growl of a beast of prey. Giving the helm in charge of the remaining quartermaster, and ordering a lieutenant to take command of the conning-tower, Captain Brookes began a tour of inspection. It was too dark to see the amount of damage done on deck, for the arc lamps had been totally destroyed, but below the glow of the incandescent lights showed that the _Olive Branch_ had not come scathless out of the fray.
