In Code of Honour, Peter Branicki, now a major in Napoleon Bonaparte's Army of Italy, and always in the company of his irascible and brash companion, Regimental Sergeant Major Raoul Aguirre, continues his adventures, fighting against the might of the Austrian Hapsburg Empire in Italy. The defeat of the Austrian white-coats allows a brief respite, but another conflict soon looms as Napoleon prepares to meet Field Marshal Würmser's massive army as it surges out of the Tyrol. But intent on relieving the siege of Mantua, will Würmser break through the French defences and will he succeed in another vital mission; escorting England's Golden Cavalry of St George? Only Peter and Raoul stand in his way.
