The Night "Lady Roberts" Was Stolen: The Battle of Helvetia
In the pitch-black, mist-shrouded hours of December 29, 1900, one of the most audacious raids of the Second Boer War unfolded on the high escarpment of the Eastern Transvaal.
By late 1900, the conventional war was technically over, but the guerrilla phase was just beginning to burn. High above the tracks near Machadodorp sat Helvetia—a vital British stronghold guarding the strategic railway link to Lydenburg. It was a well-garrisoned post, heavily fortified and boasting a massive, prized piece of British military pride: a 4.7-inch naval artillery gun affectionately named Lady Roberts.
