The army arrived before _Toulouse_ on the 27th of March, and on the 31st, a pontoon bridge being laid at St. Roques, the brigade crossed the Garonne, and seized the bridge on the Arriege, at Cintagabelle. The roads were found so bad in this direction that no further attempt was made, and the troops being recalled, the pontoon bridge was removed to Grenade, a town below Bayonne, and there laid down on the 4th of April. On this day Ponsonby's, with two other brigades of cavalry, and three divisions of infantry, crossed the river, the brigade being quartered at Grissolles, and having a strong piquet on the road to Montauban. In the course of the night the river rose so considerably, that the bridge was obliged to be removed, and the communication was cut off; Soult, however, made no attack, but employed himself in strengthening his position, which covered Toulouse. On the 8th of April the current subsided, and the pontoons were again laid down. On the 9th the troops were passing the river, and on Easter Sunday (the 10th), Soult was attacked in his position. In this attack the brigade, then commanded by Colonel Lord Charles Manners, was at different periods employed in supporting the Spanish forces, the hussar brigade, and General Clinton's division. It was not a cavalry action, and the only casualties were--Captain Burn, one trumpeter, four privates, wounded: two horses killed. The enemy abandoned his entrenchments before dusk, and took post behind the canal. The KING'S OWN were rewarded for their conduct on this occasion with the royal permission, dated 20th September, 1821, to bear the word "TOULOUSE" on their guidons. Marshal Soult retired down the canal on the 12th towards Carcasonne, and on the 13th, hostilities were terminated by the arrival of the news of the abdication of Napoleon, and of the accession of Louis XVIII. to the throne of France; Marshals Soult and Suchet, after a short delay, gave their assent to the new order of affairs, and a line of demarcation between the armies was agreed upon. The KING'S OWN went into quarters at Lanta and Caraman, and remained there until the end of May.
