This first threatening outlook was materially modified by the arrival the same day of the six naval guns from Durban, two of which were of power equal to the Boers' heavy pieces, and all of a range superior to those previously at White's disposal. By the 3rd of November a second long gun had been placed by the besiegers some 8,000 yards--between four and five miles--south-east of the town, upon Mount Umbulwani; from which, and from an eminence known indifferently as Lombard's Kop and as Little Bulwana, three miles to the northward, and also east of {p.193} the place, the worst of the heavy gun fire upon the town itself, as distinguished from the lines of defence, seems to have proceeded. On the 28th the Boers had established within 5,000 yards--less than three miles--of the western defences a third 40-pounder, to which, we learn from Joubert's despatches, his gunners with grim military humour gave the name of "Franchise"--in mockery, doubtless, of the British Government's demands on behalf of the Uitlanders. It may be mentioned here that throughout the war the Boers have shown a remarkable facility in transporting these heavy cannon, placing them with surprising rapidity in positions unexpected by their opponents. On the 29th the besieged could count twenty-six guns in place upon the lines of attack; but of these, at that time, only the three specified were guns "of position," to be reckoned as units of a siege train. The British defensive works, when finally established, measured in circuit some sixteen miles. The range of the heavier hostile guns, as revealed by their early practice, compelled an extension to this degree, in order to hold them back beyond easy {p.194} command of the town. Fortunately this perimeter, which would indicate the enclosed area to have a diameter of from five to six miles, could be manned without overtaxing the numbers of the garrison. At the moment of investment the British force fit for duty was 572 officers and 12,924 men; total, 13,496. Of these, during the siege, 88 officers and 732 men were killed or wounded; but sickness and want of food had so far further reduced the numbers that on the day of relief there were of effectives only 403 officers and 9,761 men, and of these it was significantly added that "they are the only troops fit to do even a two-miles march."[17] [Footnote 17: London _Weekly Times_, April 27, 1900.
