From Naples, General MacDonald moved north to assist Moreau in June. Trapped between two armies, Suvorov took the bold decision to concentrate his whole force against MacDonald, beating the French at the Trebbia River, close to the spot of Hannibal's great victory in 218 BC. Marching back to the north, the indomitable soldier chased the whole French Army of Italy back towards the Riviera, taking the powerful fortress of Mantua on 28 July.
