Soon afterwards, Bonaparte quitted the island of Elba, in violation of his engagements, and regained the throne of France, when the powers of Europe took arms against the usurper, and his veteran legions were overpowered in the field of Waterloo by the allied army under Field Marshal His Grace the Duke of Wellington, on the 18th of June, 1815. To replace the losses of the British army at Waterloo, additional forces were sent to the continent, and the second battalion of the TWELFTH regiment, which had returned to England a few months previously from Ireland, embarked for Flanders on the 27th of June, under the command of Colonel Julius Stirke; it landed at Ostend and advanced to Paris, where the campaign was terminated by the restoration of the Bourbon dynasty to the throne of France. Peace being again established in Europe, the battalion returned to England in December. In June, 1815, the rifle company of the first battalion proceeded to Bengal, and formed part of a field brigade assembled for service; it, however, returned to the Mauritius in November. [Sidenote: 1816] In January, 1816, the second battalion again proceeded to Ireland. [Sidenote: 1817] The first battalion continued to form part of the garrison of the Mauritius during the year 1816, and the first six months of 1817; on the 1st of July of the latter year, a serious fire broke out at Port Louis, when the exertions of the garrison to extinguish the flames, called forth the admiration and thanks of the inhabitants, which were communicated to the troops by the governor. Transports having arrived to convey the regiment to Europe, a general order was published, in which it was stated, 'Major-General Sir Edward Butler, in taking leave of the TWELFTH regiment, feels himself highly gratified in stating, that its conduct, during its services in this island, has, in every particular, been such as to meet with his highest approbation, and he begs to assure Lieut.-Colonel Forssteen, the officers, non-commissioned officers, and men of the TWELFTH regiment, that they carry with them his warmest wishes for their prosperity and welfare.' The regiment sailed from Port Louis on the 25th of July, arrived at Portsmouth on the 10th of November, and afterwards proceeded to Cork, where it landed on the 26th of December, after an absence from Europe of nearly twenty-two years. A representation of the distinguished services of the regiment in the Travancore country, and other parts of India, with its gallantry at the capture of the islands of Bourbon and Mauritius, procured for it the royal authority to bear the word "INDIA" on its colours. [Sidenote: 1818] From Cork the regiment marched to Athlone, where it arrived on the 9th of January, 1818; and joined the second battalion, which was stationed at that place. [Sidenote: 1820]
