In one hospital, where there were five hundred beds, there were seventeen hundred sick. Upwards of a thousand men died, but there were some seven thousand cases, and those who recovered were so debilitated by the effects of the disease that they were unfit for further service, and had to be sent down to the Cape or Port Elizabeth, and then to England. The seeds of this terrible scourge had been sown by the polluted waters drunk at Paardeberg. By some grievous oversight the War Office had neglected the advice of those who urged upon it the necessity of sending out a special corps to attend to sanitary points. Had this recommendation been attended to, the lives of some four thousand or five thousand men, and of over twenty thousand sent home incapacitated for work, would have been saved. Gatacre's force were able after De Wet's departure to move up to the Orange River, repairing the railway as they advanced. On arriving at Bethulie Bridge, the general found that, although that magnificent railway viaduct had been destroyed, the road bridge was still intact. It was known, however, to be mined, and there was a strong Boer force on the other side ready to blow it up the instant the British ventured upon it. It was saved, however, by the daring action of Lieutenant Popham, of the Derbyshire Regiment, and of Captain Grant, of the Sappers. The former, with two men, crept along the bridge at night and removed the detonators, took away the dynamite from under the farther span, and carried it off under a heavy fire, opened by the Boers as soon as they found that the mines were being tampered with. But there still remained heavy charges in the piers, and although the Boers could not explode these in the ordinary way, as they were commanded by our rifle-fire, they might have effected it by directing a shell-fire against them. Captain Grant, therefore, completed Popham's work by going across, removing the charges, and dropping them into the river. As the reconstruction of the railway-bridge was a work that would occupy months rather than weeks, the preservation of the road-bridge was a matter of vital importance. Gatacre's force marched across it after the enemy had been shelled out from their position on the other side, and advanced along the line of railway. The cavalry pushed forward to Springfontein, and there met two battalions of Guards sent down by train from Bloemfontein--and thus the whole line of railway was in our possession.
