It may well be asked how for so long a period as seventeen days the British could tolerate a force to the rear of them when with their great superiority of numbers they could have readily sent an army to drive it away. The answer must be that Lord Roberts had despatched his trusty lieutenant, Kitchener, to Aliwal, whence he had been in heliographic communication with Wepener, that he was sure that the place could hold out, and that he was using it, as he did Kimberley, to hold the enemy while he was making his plans for their destruction. This was the bait to tempt them to their ruin. Had the trap not been a little slow in closing, the war in the Free State might have ended then and there. From the 9th to the 25th the Boers were held in front of Wepener. Let us trace the movements of the other British detachments during that time.
Brabant’s force, with Hart’s brigade, which had been diverted on its way to Kimberley, where it was to form part of Hunter’s division, was moving on the south towards Wepener, advancing through Rouxville, but going slowly for fear of scaring the Boers away before they were sufficiently compromised. Chermside’s 3rd division approached from the north-west, moving out from the railway at Bethany, and passing through Reddersberg towards Dewetsdorp, from which it would directly threaten the Boer line of retreat. The movement was made with reassuring slowness and gentleness, as when the curved hand approaches the unconscious fly. And then suddenly, on April 21st, Lord Roberts let everything go. Had the action of the agents been as swift and as energetic as the mind of the planner, De Wet could not have escaped us.
