‘If you had permitted me to finish,’ Arthur responded coldly, ‘I would have said that Elvas will be defended by General Leite’s brigade. He’s one of the best of the Portuguese officers and I am confident that he will stand his ground - if the enemy should be unwise enough to attempt any attack from the east. The enemy will come from the north. Have no doubt about that. However, before Masséna can invade Portugal he will need to take the fortresses at Ciudad Rodrigo and Almeida as they guard the route along which he will advance. General Herrasti, the governor of Ciudad Rodrigo, has written to inform me that he has a strong garrison and plenty of supplies. He can hold out until he is relieved by a Spanish army.’ Arthur smiled. ‘I know we have not had the best of experiences at the hands of our Spanish allies . . .’

Several of the officers who had served at Talavera muttered their agreement.

‘However,’ Arthur continued, ‘they may act with a greater sense of urgency since their compatriots will be in danger. But let us assume the worst. Ciudad Rodrigo will fall. We can only hope that it delays the French advance long enough for us to improve Almeida’s defences. There too we must attempt to delay Masséna, until we have cleared the land in front of the defensive lines at Torres Vedras and completed the fortifications.’ Arthur looked round the courtyard to make sure he had every officer’s close attention. ‘The opening stages of this campaign require us to buy as much time as possible. Every day we can delay the enemy is a day gained for the improvement of our defences. Every French soldier lost in assaults on the frontier fortresses is one fewer that our men will have to face. I will be blunt with you, gentlemen: we cannot win this campaign in the conventional sense. We cannot march to battle and face Masséna on an open field and hope to defeat him. He outnumbers us, and his cavalry are some of the finest in Europe. We could not stop them flanking us. Our cavalry is far too weak to oppose the enemy horse.

‘Our goal is not to lose the campaign. If we achieve that, then we win.’ Arthur smiled sardonically. ‘Though the newspapers and other croakers in England may not be quite so accepting of this definition of victory. Do not expect to be the recipient of fine titles, pensions and other such spoils of war, gentlemen.’

His audience responded with a mixture of smiles and laughter. The newspapers and letters from England that reached the Peninsula were all too full of the opinion that Lord Wellington’s army was doing nothing in Portugal, and the soldiers should be withdrawn.
