Once Beresford’s rewritten report was safely on its way to London and the general had returned to Lisbon, Arthur directed his attention to the siege of Badajoz. On first hearing the news of the battle at Albuera he had sent for the main column, ordering that a small covering force be left behind to keep the defenders of Ciudad Rodrigo bottled up behind their walls for as long as possible. Due to the heavy losses at Albuera, Beresford’s command was too weak to continue the siege on its own and Arthur was reluctantly compelled to concentrate all his strength against Badajoz.

General Beresford and his engineers had bungled their initial attempt to capture Fort San Cristobal. The approach trenches crossed open ground and had not been dug deeply enough, so that they filled with water and mud every time it rained. They also provided inadequate shelter from enemy fire and Beresford had lost hundreds of men to the blasts of grapeshot and bursts of mortar shells as they laboured to dig their way towards the fort. The difficulties facing the allied army were compounded by the lack of decent siege guns. The guns stripped from the walls of Elvas dated back two centuries and lacked accuracy, calibre and ammunition. The batteries that had been constructed for the guns were too far from the fort and as a result it was a chance shot that ever actually struck the areas targeted for breaches.

Had there been sufficient time Arthur would have given the order to abandon the attempt on the fort and turned the army’s efforts towards the walls of Badajoz itself. However, the network of spies run by his quartermaster general, John Waters, had reported that Marshal Masséna had been replaced by Marshal Marmont, who was already marching his army south to join forces with Soult for another attempt to relieve the garrison at Badajoz. The French would be able to muster more than sixty thousand men against Arthur’s fifty thousand, a third of whom were Portuguese and Spanish. Such odds were not favourable, and unless Badajoz could be reduced quickly then the allied army would be obliged to withdraw.

As the sun rose over the rolling Spanish countryside, bathing it in a dusty orange hue, Arthur glanced down at his pocket watch.

‘Ten to six,’ he muttered.
