further compelling the British to sign the Treaty of Amiens with France, establishing a tenuous peace. Start date and nomenclature No consensus exists as to when the French Revolutionary Wars ended and the Napoleonic Wars began. Possible dates include 9 November 1799, when Bonaparte seized power on 18 Brumaire, the date according to the Republican Calendar then in use; 18 May 1803, when Britain and France ended the one short period of peace between 1792 and 1814; or 2 December 1804, when Bonaparte crowned himself Emperor. British historians occasionally refer to the nearly continuous period of warfare from 1792 to 1815 as the Great French War, or as the final phase of the Anglo-French Second Hundred Years' War, spanning the period 1689 to 1815. Historian Mike Rapport (2013) suggested using the term "French Wars" to unambiguously describe the entire period from 1792 to 1815. In France, the Napoleonic Wars are generally integrated with the French Revolutionary Wars: . German historiography may count the War of the Second Coalition (1798/9–1801/2), during which Napoleon seized power, as the Erster Napoleonischer Krieg ("First Napoleonic War"). In Dutch historiography, it is common to refer to the seven major wars between 1792 and 1815 as the Coalition Wars (coalitieoorlogen), referring to the first two as the French Revolution Wars (Franse Revolutieoorlogen). Napoleon's tactics Napoleon was, and remains, famous for his battlefield victories, and historians have spent enormous attention in analysing them. In 2008, Donald Sutherland wrote: The ideal Napoleonic battle was to manipulate the enemy into an unfavourable position through manoeuvre and deception, force him to commit his main forces and reserve to the main battle and then undertake an enveloping attack with uncommitted or reserve troops on the flank or rear. Such a surprise attack would either produce a devastating effect on morale or force him to weaken his main battle line. Either way, the enemy's own impulsiveness began the process by which even a smaller French army could defeat the enemy's forces one by one. After 1807, Napoleon's creation of a highly mobile, well-armed artillery force gave artillery usage increased tactical importance. Napoleon, rather than relying on infantry to wear away the enemy's defences, could now use massed artillery as a spearhead to pound a break in the enemy's line. Once that was achieved he sent in infantry and cavalry. Prelude Britain was irritated by several French actions following the Treaty of Amiens.
