Freire made a great show of reluctance before finally conceding. Then Arthur moved on to address the matter of the advance on Lisbon. Somerset produced Arthur’s map of the region and spread it out across the cool tiles in the shaded courtyard. Arthur indicated the coastal route leading from Leiria to the capital.

‘This is the route I intend to follow. It is open country and the enemy might well take advantage of the fact to use his cavalry to harass my advance, but until the army is reinforced I must remain in contact with the British fleet following us along the coast. If we combine our forces, we should be able to cope with anything the French can put into the field against us between here and Lisbon.’

The Portuguese general looked at the map and tapped another route, further inland.

‘He says that this is the best route. There are hills here that will conceal the advance. It is safer. He insists we should take this road,’ the guide translated.

‘Out of the question,’ Arthur replied at once. ‘It’s too far from the coast. If it’s mountainous it will only slow down my wagons and artillery. I am taking the coastal road. Tell him.’

Freire was adamant that he would march through the hills and re-join the British outside Lisbon to take part in the liberation of the capital. Then, rising to his feet, Freire announced that he was fatigued and the interview was over. He would give orders for his light infantry to join the British column.With a curt bow, he turned and disappeared inside the house.

Arthur stared after him for a moment. ‘Charming fellow.’

‘Quite,’ Somerset said softly. ‘I just hope this is not typical of the co-operation we can expect from our new allies, sir.’

‘So do I.’ Arthur took a deep breath and smiled. ‘Well, at least we have some extra men to strengthen our army. Pass the word to Colonel Trant. I believe he has some mastery of the local tongue. He can command the Portuguese contingent. Now roll up the map and let us go and hunt the French. Even if our allies prove difficult I am sure we may at least rely on the enemy to be obligingly consistent.’

The British army continued marching south under the blazing sun. To their left, across a small plain, lay the hills where General Freire’s column was supposed to be marching parallel to them, but there was never any sign of Portuguese patrols and Freire might as well be on the moon, Arthur reflected bitterly.To the right lay the sea, and some miles out the British fleet, under reduced sail, kept pace with the army. The sea was calm and sparkled seductively in the sunlight, so that the soldiers were constantly tormented by the prospect of a refreshing swim in the sea, and muttered sourly about the easy life of a sailor.
