On 20 April 1792, the French National Convention declared war on Austria. In this War of the First Coalition (1792–1798), France ranged itself against most of the European states sharing land or water borders with her, plus Portugal and the Ottoman Empire. Coalition forces achieved several victories at Verdun, Kaiserslautern, Neerwinden, but these were countered by French victories at Tourcouring (1794), Dunkirk, and Haguenau. For the French, the Rhine Campaign of 1795 proved especially disastrous, although they had achieved some success in other theaters of war (see for example, War of the Pyrenees (1793–1795).
