Baden-Powell returned to South Africa before the Second Boer War and was engaged in further military actions against the Zulus. Although instructed to maintain a mobile mounted force on the frontier with the Boer Republics, Baden-Powell amassed stores and established a garrison at Mafeking. The subsequent Siege of Mafeking lasted 217 days. Although Baden-Powell could have destroyed his stores and had sufficient forces to break out throughout much of the siege, especially since the Boers lacked adequate artillery to shell the town or its forces, he remained in the town to the point of his intended mounted soldiers eating their horses. The town had been surrounded by a Boer army, at times in excess of 8,000 men.
