It was upon October 30th that Sir George White had been thrust back into Ladysmith. On November 2nd telegraphic communication with the town was interrupted. On November 3rd the railway line was cut. On November 10th the Boers held Colenso and the line of the Tugela. On the 14th was the affair of the armoured train. On the 18th the enemy were near Estcourt. On the 21st they had reached the Mooi River. On the 23rd Hildyard attacked them at Willow Grange. All these actions will be treated elsewhere. This last one marks the turn of the tide. From then onwards Sir Redvers Buller was massing his troops at Chieveley in preparation for a great effort to cross the river and to relieve Ladysmith, the guns of which, calling from behind the line of northern hills, told their constant tale of restless attack and stubborn defence. But the task was as severe a one as the most fighting General could ask for. On the southern side the banks formed a long slope which could be shaved as with a razor by the rifle fire of the enemy. How to advance across that broad open zone was indeed a problem. It was one of many occasions in this war in which one wondered why, if a bullet-proof shield capable of sheltering a lying man could be constructed, a trial should not be given to it. Alternate rushes of companies with a safe rest after each rush would save the troops from the continued tension of that deadly never ending fire. However, it is idle to discuss what might have been done to mitigate their trials. The open ground had to be passed, and then they came to--not the enemy, but a broad and deep river, with a single bridge, probably undermined, and a single ford, which was found not to exist in practice. Beyond the river was tier after tier of hills, crowned with stone walls and seamed with trenches, defended by thousands of the best marksmen in the world, supported by an admirable artillery. If, in spite of the advance over the open and in spite of the passage of the river, a ridge could still be carried, it was only to be commanded by the next; and so, one behind the other, like the billows of the ocean, a series of hills and hollows rolled northwards to Ladysmith. All attacks must be in the open. All defence was from under cover. Add to this, that the young and energetic Louis Botha was in command of the Boers. It was a desperate task, and yet honour forbade that the garrison should be left to its fate. The venture must be made.
