If Bonaparte had indeed suffered a serious defeat then he would be hard pushed to reinforce the army under Marshal Soult that was facing Arthur. Which was just as well, since Soult already had nearly as many men, and more artillery and cavalry, than Arthur. A few years before, Arthur would have been far more cautious about taking the war on to enemy soil before his lines of communication were securely guarded. As things stood, the enemy still held Pamplona, and Marshal Suchet and his army were still in the field in the region of Valencia. However, Suchet showed little sign of stirring from what had become his personal fiefdom, and the garrison of Pamplona was under siege by a Spanish army. Accordingly, Arthur felt the risks were acceptable. In any case, his political masters in London had allowed the allied army’s swift advance and spate of victories to go over their heads and had insisted that Arthur proceed with an invasion of France.

Thus it had always been during the war in the Peninsula, he sighed wearily as he crossed the bridge and entered the town gate of St-Jean-de-Luz, touching the brim of the oilskin covering his cocked hat in response to the salutes of the sentries. His caution and careful planning had ensured British success, so far. His country was grateful to him, and his army trusted him, the latter being by far the more valued by Arthur. No amount of titles, spoils of war and parliamentary votes of thanks ever made a better general of a man, nor a better man of a general, he reflected.

He stopped a civilian for directions to the mairie where Somerset had been sent to set up the army’s headquarters. The man briefly registered a look of surprise when Arthur addressed him in French, but he seemed almost unconcerned by the presence of so many English soldiers in his town. He turned and pointed towards the end of the street, where it appeared to open on to a small square. Arthur thanked him and walked his horse on. As he clopped into the square he noted with approval that a number of provosts were patrolling the area, keeping a watchful eye on the soldiers to ensure that they did not breach Arthur’s orders concerning respectful treatment of French civilians and their property. More than ever he was dependent upon the goodwill of the locals. The allied army was no longer liberating a people from an invader. Now the allies were the invaders and Arthur knew it was vital that his men did nothing that might provoke the French civilians.

Arthur entered the mayor’s reception chamber and handed his coat and hat to a corporal standing at the door. As soon as he saw that his commander had arrived Somerset rose from his desk and hurried over to greet him.

‘The battle reports indicate we have taken every one of our objectives, sir. The first news from our cavalry patrols is that Soult is retreating towards Bayonne.’
