Napoleon abdicated on 6 April 1814, but news did not reach the south of France until after Wellington’s Anglo-Portuguese and Spanish army had fought a battle against Marshal Nicolas Soult’s French army at Toulouse.
Wellington had defeated Soult at Orthez on 27 February. The 4th and 7th Divisions of Wellington’s army, commanded by Lord Beresford, entered Bordeaux without a fight on 12 March. The mayor, Jean-Baptiste Lynch, grandson of an Irish Jacobite, and many of the locals supported the Bourbon King Louis XVIII. Wellington encountered little opposition from partisans in south west France. Ralph Ashby comments that:
The area was hardly a Bonapartist stronghold to begin with…Bourbon sympathies ran higher than elsewhere in France.
More importantly, Wellington was the one Allied army commander who kept a tight rein on his troops. Looting was absolutely forbidden, on pain of hanging…Wellington took care of his supply lines, and paid for requisitions in full.
The 7th Division remained at Bordeaux, but Beresford and the 4th Division rejoined the army on 18 March. whereupon it resumed its pursuit of Soult across south west France. On 20 March Soult managed to evade an attempt to pin his army against the Pyrenees at Tarbes. Two of the roads east were cut, but the French held the one to Toulouse for long enough to escape.
Jac Weller points out that Wellington had a number of problems: he would be outnumbered if Soult could combine with Marshal Louis Gabriel Suchet’s army, which was in Catalonia; operating in enemy territory, he had poor maps and lacks the accurate intelligence that he had received in Spain and Portugal; and he was not fully informed about the course of the campaign further north.
Toulouse was on the east of the Garonne, a wide river. It contained a large arsenal and was surrounded by thick walls, but it lacked outworks, meaning that Wellington’s siege train could breach its walls if the guns could get close enough. The suburb of St Cyprien, to the west of the river, was fortified.
Crossing the Garonne was difficult. The first attempt was made at Portet five miles south of Toulouse after dark on 27 March. It had to be abandoned because the pontoon bridge was 80 feet too short to cross the river there.
The Garonne narrowed three miles further south above its junction with the Ariège. On 30 March the pontoon bridge was laid there, and 13,000 men under Sir Rowland Hill crossed. However, they could not cross the Ariège because there was no bridge across it and no other pontoon. Moreover, there was no road capable of carrying wheeled transport to Toulouse.
The second attempt had to be abandoned, with the troops returning across the pontoon. The French did not discover the first attempt at all, and did not find out about the second one until a day later. Soult sent two divisions, with two more in reserve, to confront Hill once he had crossed the Ariège, but the lack of roads prevented the French advancing. Soult concluded that the British move had been a feint.
Wellington now realised that he could only cross the Garonne north of Toulouse. A suitable spot was found, and 18,000 men under Beresford crossed on 4 April. The pontoon bridge was barely wide enough to cross the river at this point. It was broken after heavy rain caused the river to rise, isolating the troops who had crossed. They were, however, in a strong defensive position, and Soult did not attack them. Sir Charles Oman says that he thought that most of Wellington’s army had crossed the Garonne. By 7 April the river had fallen, and the bridge had been repaired.
Wellington’s 49,000 men began the assault on Toulouse and its 42,000 defenders on 10 April. Hill’s corps was to demonstrate at St Cyprien to the west of the Garonne. On the other side of the river Sir Thomas Picton’s 3rd Division and Karl von Alten’s Light Division were to threaten the Toulouse. The main attack was to be made further north, against the Calvinet ridge, which looked down on the city.
The Calvinet would be attacked from the north by two Spanish divisions under General Manuel Freire, supported by Portuguese artillery, and from the east by the 4th and 6th Division commanded by Beresford. Beresford’s troops had to march further in order to get into position, so Freire was ordered to wait until they were ready.
The attack did not go to plan. Hill’s demonstration was well executed, but failed to fool Soult, who moved troops from St Cyprien to the Calvinet. Picton pushed on too far, taking unnecessary casualties for no benefit. Freire launched his attack before Beresford was in position.
Wellington, seeing Freire’s move, sent orders to Beresford to attack the Calvinet immediately rather than waiting to get into the originally planned position, even though this meant that his troops would be attacking a strongly defended part of the ridge. Freire’s assault had been beaten back by the time that Beresford received this order, so he ignored it and continued with the original plan, which was to attack the ridge at a more weakly defended point.
Beresford’s troops advanced towards the ridge, beat off a French counter-attack, and took part of the ridge with relatively light casualties. Beresford waited until his artillery had been brought up before resuming the assault. His men took the rest of the ridge with help from a further attack by Freire. It was forced back, but helped Beresford by distracting a large number of French troops.
Soult still held Toulouse, but his positions were vulnerable to artillery fire from the Calvinet, and his supplies would last only a month. Wellington expected him to counter-attack on 11 April, but Soult, concerned that enemy cavalry was moving to cut him off, decided to retreat to Carcassonne.
Both side claimed to have won the Battle of Toulouse. Wellington took the city, but suffered more casualties: his army lost 655 killed, 16 missing and 3,887 wounded against French casualties of 322 killed, 541 missing and 2,373 wounded. Peter Snow writes that Wellington ‘described his rather dubious victory as a “very serious affair with the enemy in which we defeated them completely.”‘
It was very unfortunate that the poor communications meant that such a bloody battle was fought after Napoleon’s abdication. On Soult 17 April he received formal notification of Napoleon’s abdication. He signed an armistice the same day, which required the French to evacuate fortresses in Spain, but not those in France. However, two further actions took place before these orders reached every garrison.
On 14 April General Pierre Thouvenot, the French garrison commander at Bayonne, ordered his troops to sally out against the enemy troops blockading the fortress, although he had been informally informed of Napoleon’s abdication by then. British casualties were 150 killed, 457 wounded, excluding men captured, and 236 captured: many of the prisoners were also wounded, amongst them Sir John Hope, the commander of the blockading force. The French lost 111 killed, 778 wounded and 16 missing.
The garrison of Barcelona sallied against their besiegers two days later, but in this case they were unaware of Napoleon’s abdication.
Thouvenot eventually surrendered on April 27 after receiving a copy of Soult’s armistice the day before.Oman argues that the sally would have achieved nothing even if the war was continuing, noting that Wellington called Thouvenot ‘a blackguard’.
The Napoleonic War was now apparently over, but it was to resume a year later.
