In Britain, Fulton met the Duke of Bridgewater, Francis Egerton, whose canal, the first to be constructed in the country, was being used for trials of a steam tug. Fulton became very enthusiastic about the canals, and wrote a 1796 treatise on canal construction, suggesting improvements to locks and other features.
The French then focused on the Austrians for the remainder of the war, the highlight of which became the protracted struggle for Mantua. The Austrians launched a series of offensives against the French to break the siege, but Napoleon defeated every relief effort, scoring victories at the battles of Castiglione, Bassano, Arcole, and Rivoli.
The next phase of the campaign featured the French invasion of the Habsburg heartlands. French forces in Southern Germany had been defeated by the Archduke Charles in 1796, but the Archduke withdrew his forces to protect Vienna after learning about Napoleon's assault.
