 France considered both the extant Dutch fleet and the large Dutch shipbuilding capacity very important assets, but after the Battle of Trafalgar gave up its attempt to match the British fleet, despite a strong Dutch lobby to this effect.After the incorporation of the Netherlands in the French Empire in 1810, Britain finished seizing all the Dutch colonies.With the signing of the Anglo-Dutch Treaty of 1814, Britain returned all those colonies to the new Kingdom of the Netherlands, with the exception of the Cape, Ceylon, and part of Dutch Guyana.
