During the night Marshal Soult retreated towards _Toulouse_, followed on the 21st of March by the allies, who continued their advance, until on the 26th they arrived in presence of the French army. The town of _Toulouse_ is surrounded on three sides by the Canal of Languedoc and the Garonne; on the left of that river, the suburb, which the enemy had fortified with strong field-works in front of the ancient wall, formed a good _tête-de-pont_. The city itself was only accessible from the south, and its strong though old-fashioned walls had been rendered more defensible by redoubts, and by an exterior line of entrenchments on a strong and rugged range of heights, about two miles in length beyond the canal. On the 28th the enemy’s troops were driven within the suburb of St. Cyprien, and several attempts were made to attack them by crossing the Garonne above Toulouse. Operations were, however, impeded by the floods and rapidity of the river, until the 3d of April, when the third, fourth, and sixth divisions, with three brigades of cavalry, under Marshal Beresford, passed over by a pontoon bridge fifteen miles below Toulouse; but the crossing of the remainder of the army was again impeded by the rising of the river, which caused the removal of the bridges, until the 8th, when the Marquis of Wellington crossed, and advanced within five miles of Toulouse; Lieut.-General Sir Rowland Hill, with two divisions, remaining on the left bank. In the battle of _Toulouse_, which began about six o’clock in the morning of the 10th of April, it was the good fortune of the THIRTY-SIXTH to commence the attack of the sixth division. The Marquis of Wellington’s plan of attack was for Marshal Sir William Beresford, who was on the right of the Ers with the fourth and sixth divisions, to cross that river at the bridge of Croix d’Orade, to gain possession of Montblanc, and to march up to the left of the Ers to turn the enemy’s right, while Lieut.-General Don Manuel Freyre, with the Spanish corps under his command, supported by the British cavalry, attacked the front.
