 Because it only pertains to wars involving any of the Coalition parties, not all wars counted amongst the French Revolutionary and Napoleonic Wars are considered "Coalition Wars".For example, the French invasion of Switzerland (1798, between the First and Second Coalition), the Stecklikrieg (1802, between the Second and Third Coalition) and the French invasion of Russia (1812, between the Fifth and Sixth Coalition) were not "Coalition Wars", since France fought against a single opponent.The main European powers who forged the various anti-French Coalitions were Great Britain, Russia, Austria and Prussia, although except for Great Britain not all of them were involved in every Coalition.
