 			<p>The evening had been golden; but, after all, the day was to close in cloud and tempest. Imperial needs, imperial ambitions, involved the country in the South African War. There were checks, reverses, bloody disasters; for a moment the nation was shaken, and the public distresses were felt with intimate solicitude by the Queen. But her spirit was high, and neither her courage nor her confidence wavered for a moment. Throwing her self heart and soul into the struggle, she laboured with redoubled vigour, interested herself in every detail of the hostilities, and sought by every means in her power to render service to the national cause. In <time datetime="1900-04">April 1900</time>, when she was in her eighty-first year, she made the extraordinary decision to abandon her annual visit to the South of France, and to go instead to Ireland, which had provided a particularly large number of recruits to the armies in the field. She stayed for three weeks in Dublin, driving through the streets, in spite of the warnings of her advisers, without an armed escort; and the visit was a complete success. But, in the course of it, she began, for the first time, to show signs of the fatigue of age.<a href="endnotes.xhtml#note-421" id="noteref-421" epub:type="noteref">421</a></p>
 			<p>For the long strain and the unceasing anxiety, brought by the war, made themselves felt at last. Endowed by nature with a robust constitution, Victoria, though in periods of depression she had sometimes supposed herself an invalid, had in reality throughout her life enjoyed remarkably good health. In her old age, she had suffered from a rheumatic stiffness of the joints, which had necessitated the use of a stick, and, eventually, a wheeled chair; but no other ailments attacked her, until, in <time datetime="1898">1898</time>, her eyesight began to be affected by incipient cataract. After that, she found reading more and more difficult, though she could still sign her name, and even, with some difficulty, write letters. In the summer of <time datetime="1900">1900</time>, however, more serious symptoms appeared. Her memory, in whose strength and precision she had so long prided herself, now sometimes deserted her; there was a tendency towards aphasia; and, while no specific disease declared itself, by the autumn there were unmistakable signs of a general physical decay. Yet, even in these last months, the strain of iron held firm. The daily work continued; nay, it actually increased; for the Queen, with an astonishing pertinacity, insisted upon communicating personally with an ever-growing multitude of men and women who had suffered through the war.<a href="endnotes.xhtml#note-422" id="noteref-422" epub:type="noteref">422</a></p>
