The "Daily Mail" newspaper recruited Lady Sarah after one of its correspondents, Ralph Hellawell, was arrested by the Boers as he tried to get out of the besieged town of Mafeking to send his dispatch. She was in the right place at the right time to step into the journalistic breach, having moved to Mafeking with her husband, Lt.-Col. Gordon Chesney Wilson, at the start of the war, where he was "aide-de-camp" to Col. Robert Baden-Powell, the commanding officer at Mafeking. Baden-Powell asked her to leave Mafeking for her own safety after the Boers threatened to storm the British garrison. This she duly did, and set off on a madcap adventure in the company of her maid, travelling through the South African countryside. Eventually, she was captured by the Boers and returned to the town in exchange for a horse thief being held there.
