Rundle, who for two months had been painfully, but not with unnecessary deliberation, pushing his force up the right bank of the Caledon, was at first ordered by Hunter to watch Slabbert's Nek, but on a report that the Boers were about to come out through Commando Nek, he was sent back. The movement, though justified on the assumption that the report, which came on good authority, was correct, was unfortunate, as it left the key of the gate at Slabbert's Nek in the enemy's hands, and allowed De Wet to escape. De Wet had assigned to himself the initial movement of the withdrawal, and left the rest of the programme to develop itself without him. Roux was put in charge of the Brandwater Basin. De Wet was an unpopular leader. His attempts to leaven the commandos with a little of the military spirit were resented. He had from the first, with only partial success, set his face against the incumbrance of wagons which marched with every commando. On the way to Sannah's Post he had cashiered a commandant named Vilonel for disobeying his orders with regard to transport. His nomination of Roux did not give satisfaction. The partisans of other leaders protested, and it was determined to settle by election the question of the Chief Command. In the meantime, the management was in the hands of a triumvirate composed of Roux, Olivier, and Martin Prinsloo. In the chaos, the commandos which De Wet had arranged should break out remained in the trap and simplified Hunter's task. In succession, Retief's Nek, Slabbert's Nek, and Commando Nek were taken, the latter by Rundle, who on July 28 joined Hunter at Fouriesburg. Witnek had been abandoned by the Boers, who now had only Naauwpoort Nek and the scarcely practicable Golden Gate open to them. The Nek was closed by Hunter on July 27, and a position outside the Golden Gate, but not the Gate itself, was occupied. The greater part of the Boer force was now practically sealed up in the Basin. A Council of War was held to elect a new chief commandant. Had the vote been taken ten days earlier the situation might possibly have been saved, but the belated proceedings which displayed the weakness of a democratically organized army, and which, in the absence of representatives of the commandos not on the spot, were of doubtful validity, only added to the existing confusion. Prinsloo, however, seems to have been informally chosen.
