Near Okanjande the first great development in General Botha's final strategy occurred. The northern advance was being conducted as follows. Brigadier-General Brits, on the left, remained at Otjitasu, leaving it on June 30. General Botha, with his command, in the centre, was holding to the narrow gauge Karibib-Otavi-Tsumeb-Grootfontein Railway, and General Myburgh's column to the right. Brigadier-General Brits now branched away to Otjitasu, making for Outjo, Okanknejo, and across the Etoscha Pan to Namutoni. The other columns moved on, trekking night and day, as in the great advance across the Namib Desert. Headquarters made Okaputa on June 29; paused the next day, and on July 1 the Staff, leaving Okaputa at 8 o'clock in the morning, reached Otavi and Otaviafontein at 4.30 p.m., close on the heels of an engagement at Osib between the Germans and Brigadier-General Manie Botha, who had pushed on with the Orange Free State Brigade at 6.30 the previous evening, June 30. This engagement took place in the now intensely thick bush country. In defeating the enemy, at a cost of a dozen casualties, Brigadier-General Manie Botha succeeded in securing the finest water supply the Union Forces had yet seen, and so swift and resolute was the fighting of the burghers that the enemy fled to their last strong-hold northward towards Tsumeb. Before striking the enemy in this action the Free State Brigade, and their accompanying batteries from the 2nd South African Mounted Riflemen, had trekked forty-two miles in sixteen hours without halt for any kind of a rest. Behind them, in support, came the force, consisting of the 6th Mounted Brigade, with the 1st South African Mounted Riflemen Batteries, who did a similar trek, through thickest bush, covering almost fifty miles in twenty hours. And the animals had come through from Karibib--almost two and a half degrees of latitude south. At the same time as Brigadier-General Manie Botha had left Okaputa, Brigadier-General Lukin, with the 6th Mounted S.A.M.R. Brigade, had left Omarasa. We had therefore a perfect network of highly mobile forces advancing on the German position somewhere north. Away on the right, from Windhuk and Okahandja through the Waterberg, was Brigadier-General Albert's column. On his left was Brigadier-General Myburgh. Nearer the railway was Brigadier-General Manie Botha. Next came the Commander-in-Chief with Headquarters Staff and Bodyguard; and, further, General Lukin. For the time being Brigadier-General Brits, on the extreme left, had disappeared. [Illustration: The Last Phase.
