On 17th April, seeing that the force from Rhodesia under Colonel Plumer was not sufficiently strong to fight its way through, and that the expedition that had been sent there by way of Beira could hardly, in spite of the tremendous exertions that were being made, be depended upon to join Plumer in time, Lord Roberts ordered that a flying column of mounted troops, under the command of Colonel Mahon of the 8th Hussars, should start from Kimberley not later than the 4th of May. Yorke, after leaving Lord Roberts, at once returned to his quarters and told his host that he was going to Kimberley, and should probably not return to Bloemfontein, but should rejoin the army on its way up the country. "Are you going to take your man with you?" "No, sir, I shall have to travel fast, and may have to ride for my life. I shall take my best horse. If you will kindly allow me to leave the other in your stable, my man can bring him on when the army moves." "That I will gladly do, but you must let me lend you a better mount than the one you are taking. I have two in my stable of which you can take your choice. I think either of them is as good as any in the state--or, I should say, in the colony, as, since your general's proclamation, we are all British subjects." "I could not think of accepting your kind offer, sir." "But I insist upon it, Mr. Harberton. Indeed you will be doing me a service, for since the war began I have had no use for my horses at all, and they sadly want exercise. A month's hard work will be of real benefit to the animal; and I should benefit too, for time was when I did not mind how fiery a horse was, but now that I am getting on in life I am not fond of having to fight with my mount." "I am extremely obliged to you, sir; but I do not see how I shall be able to send it back again to you." "When you get to Johannesburg you can leave it with Mr. Chambers, he and I will arrange how it is to be returned. In fact, as soon as matters are settled down I shall certainly go there myself. Do not let that trouble you in any way." Yorke gratefully accepted the offer. Both of his own horses had felt the hard work to which they had been subjected, that which Hans rode more than his own; for the latter had been kept hard at work since their arrival at Bloemfontein, and was certainly not fit to start on a journey of many hundred miles. Both horses could, without difficulty, go on at the rate the army was likely to advance, especially after having another ten days' rest at Bloemfontein.
