"Yes. Don't worry," replied Lennox shortly. "Here, quick!" he cried excitedly. "Take your glass and look straight away yonder to the left of the laager we took." "Eh? Yes! All right. I see. Here, send word to the chief. They're coming on fast now; three clouds of them. Reinforcements. Why don't those fellows make the big gun begin to talk?" "Because they can see what I can, Bob," cried Lennox joyously. "Look again. Lance-tips glittering in the sun. Our men. Hurrah! Strong bodies of cavalry. Why, Bob, they'll catch the enemy in the open now. The siege is up. Hush! Don't shout." "Why, man? It will encourage the lads." "And warn the enemy that help is coming. Five minutes more ignorance will be worth anything to the relief force. I'll go to the chief at once." There was no need. Almost at that moment the colonel had caught sight of the lance-tips through his glass; but quite ten minutes more--minutes crowded with excitement--elapsed before the attacking party were aware of the danger in their rear, and then came the terrible reverse. Boers began running back to where their ponies were being held out of rifle-shot, but running in vain, for the British cavalry were there first, spurring their steeds and stampeding the ponies, sending them in all directions prior to charging through and through the retreating parties, and keeping up the pursuit until recalled. Others of the relief force had meanwhile been aiming at the three laagers, into which the infantry dashed, the first warning of this received at the kopje being through the cessation of the shelling, for the guns were either silenced or put out of action, the whole of the Boer force literally melting away. It was one of the most brilliant episodes of the war; and that night, the supplies having come up, the relief party were hoarse with cheering the men whom they dubbed British heroes, and all was festivity and joy. No, not all; for during the long watches of that night, with the stars looking piercingly through the cold, clear air, parties were out, British and Boer, searching far and wide, and the ambulance-wagons creaked and rattled with their terrible loads, while Doctor Emden, the doctors of the relief expedition, and those working for the Boers were busy till morning. It was Lennox and his comrade who, being still only invalids, had the forethought to make their way at sunrise to where the doctor had been working all the night, and they found him lying utterly exhausted upon an old greatcoat, fast asleep. Lennox touched him gently, and he sprang up. "Yes, all right," he said; "I'll come. How many this time?--Eh? What! you, my dear boys? Hurt?" "No, no, doctor; drink this," said Lennox gently, and he held out a steaming tin.
