The capture of New Orleans appearing impracticable, a temporary road was constructed through the morass, and the regiments having reached the lake by a night march, embarked in boats and returned to the fleet. An attack on Mobile was afterwards resolved on, and the KING'S OWN were engaged in the siege of _Fort Bowyer_, which commanded the entrance to the harbour; this place surrendered on the 12th of February, and the second American regiment of the line having marched out with the honours of war, delivered its arms and colours to the KING'S OWN. Further hostilities against the Americans were, however, prevented by a treaty of peace, and the FOURTH being ordered to return to England, arrived on the 16th of May at Portsmouth, from whence they sailed to the Downs; and having landed on the 18th, were stationed in Deal barracks. On the extension of the Order of the Bath, in the beginning of this year, Lieut.-Colonel FRANCIS BROOKE and Brevet Lieut.-Colonels JOHN PIPER and ALURED DODSWORTH FAUNCE, of the KING'S OWN, were nominated Companions of that Order. On the arrival in England of the surviving officers and men of the KING'S OWN from these difficult enterprises in America, they found Europe involved in another war. Bonaparte had violated the treaty of 1814; he had quitted Elba; had invaded France with a few guards; had been received with acclamations by the French army; and while Louis XVIII. fled to Flanders, Napoleon had re-ascended the throne of France. The nations of Europe declared war against the usurper; and the KING'S OWN were immediately ordered to proceed to Flanders to engage in the approaching contest. The effective men of the second battalion were added to the first battalion, which again embarked for foreign service on the 10th of June, and having landed at Ostend on the 12th, proceeded up the country. Bonaparte attacked the advanced-posts of the army commanded by Field-Marshal His Grace the Duke of Wellington in the middle of June; and the KING'S OWN, by forced marches, arrived at the position in front of the village of _Waterloo_ on the morning of the 18th of June, about an hour before the battle commenced.
