They were found to have originally been British and had been captured by the Boers in the aftermath of the Jameson Raid. Aftermath The way was now clear for the British detachment at Dundee to fall back on the main British force, but Sir George White feared that 10,000 Boers from the Orange Free State were about to attack Ladysmith, and ordered the force at Elandslaagte to fall back there. The British were tired and many officers had been killed, and the retreat became a disorderly scramble. The detachment at Dundee was once again isolated, and was forced to make an exhausting detour before they could reach safety. The Boer forces re-occupied Elandslaagte two days later. General Kock was captured by the British and died from his wounds shortly after the battle. Also captured in the battle was Adolf Schiel, a German officer who had lived in South Africa since 1878. Schiel, who held the commission of Lieutenant Colonel, led a German commando in the battle. Schiel returned to Germany after the war, but died from wounds he had received at Elandslaagte in 1903. Among the British dead was Colonel John James Scott-Chisholme, commander in the Imperial Light Horse. He was killed while leading from the front and encouraging his men by waving a coloured sash. The Battle was also notable for being the first and last battle of the volunteer Hollanderkorps. The Hollanderkorps was a group of ca. 150 Dutch volunteers which had been established a mere month earlier. During the battle the Hollanderkorps suffered 9 fatalities, including Herman Coster, along with fellow officer Cars Geerts de Jonge and seven soldiers: P.J. van den Broek, H. van Cittert, J.A. Lepeltak Kieft, Jan Moora, J.Th. Rummeling, M. Schaink, and F.W. Wagner. A further 35 of the Hollanders were taken prisoner by the British. Among the prisoners was Willem Frederik Mondriaan (brother of the Dutch artist Piet Mondrian) who was wounded in the battle. Although he was able to crawl away from the battlefield he was taken prisoner by the British shortly after. He was later sent to Saint Helena as a prisoner of war, returning to South Africa in 1903. Cornelis Vincent 'Cor' van Gogh, the brother of the Dutch artist Vincent van Gogh, also fought in the battle where he was wounded and taken prisoner. He died shortly after. The Boer generals were deeply unhappy with the Hollanderkorps' performance,
