Ladysmith, and its relief, as a symbol in the Boer War is a rather complex and murky story. When the war started, the Brits were pretty cocky they’d win easily and hands down. Instead, in the early days in Natal, the Boers easily whipped a Brit force sent out from Ladysmith and the Brit commanding general, Lieutenant General Sir George White, pulled back into Ladysmith, where the force got trapped and besieged. This gave the Boers the strategic initiative. The Brits sent out reinforcements, named General Sir Redevers Buller, to command. But having to relieve Ladysmith became Bullers’ top priority. It was a tough job, as Ladysmith was behind a river overlooked by mountains. The Boers had good defensive lines and rapid firing Mausers, which they knew how to use. Trying to break through, the Brits lost several famous battles, Spion Cop among them.
When the Brits finally relieved Ladysmith, privately many English officers were exasperated at White. They thought the Ladysmith garrison force had just quit on the war and White had just lost his nerve. It all was a bit like Rosecrans, the Battle of Chickamauga, and the siege of Chattanooga in the Civil War. Buller lost his job and his career was ruined. But for morale and propaganda reasons all this was hushed up and the Relief of Ladysmith became a myth, with White elevated to the status of hero.
