On the 10th of December the Dutchman Viljoen, who was a prisoner, was exchanged for Lady Sarah Wilson. The story of this enterprising lady is one of remarkable interest. In the beginning of the siege she left Mafeking and rode to Setlagoli Hotel, where she arrived on the same night. No sooner was she asleep than the rattle and roar of musketry commenced. This was afterwards discovered to be the gallant fight of Lieutenant Nesbitt on the armoured train, which has been described in the opening story of the siege. Poor Nesbitt, it may be remembered, was taken prisoner. Lady Sarah, a day or two after the fight, rode to the scene of the engagement and photographed the wreck. Later on, this intrepid lady moved from Mosuti to the care of a colonial farmer, and with great difficulty and much expenditure of energy and coin, she managed to induce the natives to provide her with information. All this time she and her friends were subject to the insults of the Boers. At one period she was declared to be the sole survivor of Mafeking, in hiding in the disguise of a woman. At another, she was believed to be the wife of one of the British generals. Others declared that the extraordinary lady was a member of the Royal Family, who was acting as spy on the doings of the Boers in the Colony. After moving to Vryburg, life for her became more exciting still. A young Boer passed her off as his sister, and some loyalists in the town gave her shelter, and helped her to obtain official despatches and news. But her state was far from comfortable, for most of her excursions had to be made under the shadow of night, and her days were spent enclosed in a room at the hotel. When Lady Sarah desired to leave the town, her exit was not so easy. The magistrates had issued orders that no one was to leave, and but for the kindness of her "brother Boer," she might not have been able to depart. Their journey was commenced at four in the morning, while it was still dark, and before leaving the town they had to submit to a search of their car, lest it should contain any contraband of war.
