Lord Roberts expressed his satisfaction at the brilliant work performed by the Welsh Regiment in the storming of Alexander Kopje, a feat in which they displayed consummate skill as well as amazing pluck. Some heroic actions took place during the day, particularly in connection with the supply of ammunition, which ran short owing to the necessity of relieving the infantry for their heavy march, of fifty rounds apiece. Some dastardly ones were also practised by the Boers, who, finding themselves in a perilous situation, the artillery in front and a squadron of mounted infantry hovering on their flank, hoisted a white flag and threw up their hands in token of surrender. Naturally the British accepted the sign, and, while they were approaching the Dutchmen, some others of their number hastened to pour a volley into the British ranks. Lord Roberts himself having been a witness of this treacherous act, remonstrated with the Boer leaders, and ordered that in future if such action were repeated the white flag should be utterly disregarded. The following protest was made by the Commander-in-Chief:-- "To their Honours the State Presidents of the Orange Free State and South African Republic. "Another instance having occurred of a gross abuse of the white flag, and of the signal of holding up the hands in token of surrender, it is my duty to inform your Honours that if such abuse occurs again, I shall most reluctantly be compelled to order my troops to disregard the white flag entirely. "The instance occurred on the kopje east of Driefontein Farm yesterday evening, and was witnessed by several of my own staff-officers as well as by myself, and resulted in the wounding of several of my officers and men. "A large quantity of explosive bullets of three different kinds was found in Cronje's laager, and after every engagement with your Honours' troops. "Such breaches of the recognised usages of war and of the Geneva Convention are a disgrace to any civilised Power. "A copy of this telegram has been sent to my Government, with a request that it may be communicated to all neutral Powers."
