With three Military Crosses, three Croix de guerre, a Legion d'honneur and a papal knighthood for his heroics during the Second World War, Sir Tommy Macpherson is the most decorated living soldier of the British Army.

Yet for 65 years the Highlander's story has remained untold. Few know how, aged 21, he persuaded 23,000 SS soldiers of the feared Das Reich tank column to surrender, or how Tommy almost single-handedly stopped Tito's Yugoslavia annexing the whole of north-east Italy. Twice captured, he escaped both times, marching through hundreds of miles of German-held territory to get home.

Still a schoolboy when war broke out, Tommy quickly matured into a legendary commando, and his remarkable story features a dizzyingly diverse cast of characters, including Winston Churchill, Field Marshal Montgomery and Charles de Gaulle.
