Bonaparte, after having been crowned King of Italy, and having added Genoa to his empire, proceeded to Boulogne and reviewed his army; and immediately afterwards marched against the forces of Russia and Austria, to crush at once the coalition forming against his interests, in which the British cabinet was taking a decided part. At the same time the French troops were withdrawn from Hanover, which country they had seized on soon after the resuming of hostilities in 1803. On the 21st of October the glorious victory at Trafalgar was won by the fleet, which gave Great Britain the uncontrolled sovereignty of the sea: and on the 27th of that month the first battalion of the KING'S OWN embarked at Ramsgate for Hanover. Having landed at Cuxhaven on the 19th of November, it marched up the country and was cantoned at Blumenthal, where it was formed in brigade with the twenty-third and twenty-eighth regiments under Major-General Honourable E. Paget; the British troops in Hanover designed to co-operate with the continental powers being under the orders of Lieut.-General Lord Cathcart. Meanwhile the Austrians had been overpowered by Bonaparte, who had taken possession of Vienna; and the united Austrian and Russian armies were defeated in the beginning of December at Austerlitz, which established the preponderance of French power. In a subsequent treaty concluded at Vienna, it was stipulated, that Hanover should be occupied by the Prussians, and the British troops under Lord Cathcart retreated to Bremen and embarked for England. [Sidenote: 1806] The first battalion of the KING'S OWN landed at Yarmouth in February, 1806, and marched to Woodbridge barracks; from whence it proceeded in May to Colchester: the second battalion was quartered at Chelmsford. [Sidenote: 1807] The influence of French councils at the court of Denmark, with the expectation that its navy would be employed by Bonaparte against Great Britain, occasioned the British court to resolve to obtain possession of the Danish fleet either by treaty or force, and to retain it until the conclusion of the war. An armament was fitted out for this service, and the first battalion of the KING'S OWN embarked at Harwich on the 25th of July, to form part of the land force under the orders of Lieut.-General Lord Cathcart. The Danish government not acceding to the proposed conditions, the army landed on the island of Zealand, and took up a position before _Copenhagen_, the KING'S OWN being formed in brigade with the twenty-third regiment, under the orders of Major-General Grosvenor. After a bombardment of three days the city surrendered, and the fleet was given up. The KING'S OWN, commanded by Lieut.-Colonel Wynch, occupied the citadel, where Lord Cathcart fixed his head-quarters. On the evacuation of Copenhagen, the KING'S OWN re-embarked, and after landing at Deal on the 6th and 7th of November, marched to Colchester. The second battalion had, in the mean time, proceeded to Jersey.[32]
