Candidate passages:
The book covers the time period between April 1809, and 1815, the climax of the conflict at the battle of Waterloo.
At the start of the novel, Napoleon is facing increasing pressure as his marshals are repeatedly defeated by Arthur Wellesley, leading the allied armies of Britain and Spain.
The plot of the novel revolves around Napoleon's wars in central Europe, and failed invasion of Russia, as his armies rapidly lose men and their reputation for invincibility.
Running parallel to this story, Arthur Wellesley is leading the allied forces to victory in the Peninsula War, before invading Southern France.
The novel ends with Napoleon and Wellington finally meeting in battle, at Waterloo. 
Napoleon had hardly succeeded in putting down the revolt in Germany when the Tsar of Russia himself headed a European insurrection against Napoleon.
To put a stop to this, to ensure his own access to the Mediterranean and exclude his chief rival, Napoleon made an effort in 1812 against Russia.
Despite his victorious advance, the taking of Smolensk, the victory on the Moskva, and the entry into Moscow, he was defeated by the country and the climate, and by Alexander's refusal to make terms.
After this came the lamentable retreat in the harsh Russian winter, while all Europe was concentrating against him.
Pushed back, as he had been in Spain, from bastion to bastion, after the action on the Berezina, Napoleon had to fall back upon the frontiers of 1809, and then—having refused the peace offered to him by Austria at the Congress of Prague (4 June–10 August 1813), from a dread of losing Italy, where each of his victories had marked a stage in the accomplishment of his dream—on those of 1805, despite Lützen and Bautzen, and on those of 1802 after his defeat at Leipzig, when Bernadotte – now Crown Prince of Sweden – turned upon him, General Moreau also joined the Allies, and longstanding allied nations, such as Saxony and Bavaria, forsook him as well.
Following his retreat from Russia, Napoleon continued to retreat, this time from Germany.
After the loss of Spain, reconquered by an allied army led by Wellington, the rising in the Netherlands preliminary to the invasion and the manifesto of Frankfort (1 December 1813) which proclaimed it, he had to fall back upon the frontiers of 1795; and then later was driven yet farther back upon those of 1792—despite the campaign of 1814 against the invaders.
Paris capitulated on 30 March 1814, and the "Delenda Carthago", pronounced against Britain, was spoken of Napoleon.
The Empire fell with Napoleon's abdication at Fontainebleau on 11 April 1814.
After a brief exile at the island of Elba, Napoleon escaped, with a ship, a few men, and four cannon.
The King sent Marshal Ney to arrest Napoleon.
Upon meeting the army sent to arrest him, Napoleon dismounted and walked into firing range, saying "If one of you wishes to kill his Emperor, here I am!"
But instead of firing, they went to join Napoleon's side shouting "Vive l'Empereur!"
Napoleon recaptured the throne temporarily in 1815, reviving the Empire in what is known as the Hundred Days.
However, he was defeated by the Seventh Coalition at the Battle of Waterloo.
He surrendered himself to the Coalition and was exiled to Saint Helena, a remote island in the South Atlantic, where he remained until his death in 1821.
After the Hundred Days (just less than a third of a year), the Bourbon monarchy was restored, with Louis XVIII regaining the throne of France, while the rest of Napoleon's conquests were disposed of in the Congress of Vienna. 
According to a popular myth, the dish was first made after Napoleon defeated the Austrian army at the Battle of Marengo at Marengo south of Turin, Italy, when his chef Dunand foraged in the town for ingredients (because the supply wagons were too distant) and created the dish from what he could gather.
According to this legend, Napoleon enjoyed the dish so much he had it served to him after every battle, and when Durand was later better-supplied and substituted mushrooms for crayfish and added wine to the recipe, Napoleon refused to accept it, believing that a change would bring him bad luck.
This colorful story, however, is probably myth; Alan Davidson writes that there would be no access to tomatoes at that time, and the first published recipe for the dish omits them.
The more plausible explanation for the origin of the dish is that it was created by a restaurant chef to honor Napoleon's victory. 
Great Britain broke the Peace of Amiens and declared war on France in May 1803.
Napoleon set up a camp at Boulogne-sur-Mer to prepare for an invasion of Britain.
By 1805, Britain had convinced Austria and Russia to join a Third Coalition against France.
Napoleon knew the French fleet could not defeat the Royal Navy in a head-to-head battle and planned to lure it away from the English Channel.
The French Navy would escape from the British blockades of Toulon and Brest and threaten to attack the West Indies, thus drawing off the British defence of the Western Approaches, in the hope a Franco-Spanish fleet could take control of the channel long enough for French armies to cross from Boulogne and invade England.
However, after defeat at the naval Battle of Cape Finisterre in July 1805 and Admiral Villeneuve's retreat to Cádiz, invasion was never again a realistic option for Napoleon.
As the Austrian army marched on Bavaria, he called the invasion of Britain off and ordered the army stationed at Boulogne, his "Grande Armée", to march to Germany secretly in a turning movement—the Ulm Campaign.
This encircled the Austrian forces about to attack France and severed their lines of communication.
On 20 October 1805, the French captured 30,000 prisoners at Ulm, though the next day Britain's victory at the Battle of Trafalgar meant the Royal Navy gained control of the seas.
Six weeks later, on the first anniversary of his coronation, Napoleon defeated Austria and Russia at Austerlitz.
This ended the Third Coalition, and he commissioned the Arc de Triomphe to commemorate the victory.
Austria had to concede territory; the Peace of Pressburg led to the dissolution of the Holy Roman Empire and creation of the Confederation of the Rhine with Napoleon named as its "Protector".
Napoleon would go on to say, "The battle of Austerlitz is the finest of all I have fought."
Frank McLynn suggests Napoleon was so successful at Austerlitz he lost touch with reality, and what used to be French foreign policy became a "personal Napoleonic one".
Vincent Cronin disagrees, stating Napoleon was not overly ambitious for himself, that "he embodied the ambitions of thirty million Frenchmen". 
Mameluke swords were carried as dress or levée swords by officers of most light cavalry and hussar, and some heavy cavalry regiments in the British Army at various points during the 19th century, starting in the period after Waterloo.
The current regulation sword for generals, the 1831 Pattern, is a Mameluke-style sword, as were various Army Band swords.
There are a number of factors which influenced the fashion for Mameluke swords in the British Army.
Napoleon raised a number of Mameluke units during his Egyptian campaigns in the French Revolutionary Wars, leading to the adoption of this style of sword by many French officers.
In the post-Napoleonic period French military fashion was widely adopted in Britain.
The Duke of Wellington carried a Mameluke sword from his days serving in India and throughout his career.
After he defeated Napoleon his status as a national hero, Commander-in-Chief of the Forces, and then prime minister gave his tastes considerable weight.
The United States Marine Corps sword, discussed above, has been suggested as also being influential.
The 1831 Pattern General Officers' Sword is, indeed, very similar to the USMC Mameluke that pre-dated it.
