In 1899, during the Second Boer War, Lambton stopped at Mauritius, and on his own initiative picked up a battalion of soldiers stationed there. Knowing that the British forces at Ladysmith urgently needed more powerful guns, Lambton led a naval brigade to the rescue with four twelve-pounders and two other guns. The enthusiastic response in Britain to the "heroes of Ladysmith" was enormous and made Captain Hedworth Lambton a well-known public figure. He went on to be Commander of the Third Cruiser Squadron in the Mediterranean Fleet and then Commander-in-Chief of the China Station.
