Arthur looked at his brother in surprise.‘Why, Richard, have you any idea of the distances involved? Even the best supplied and disciplined of armies would be broken by such a campaign. Believe me, such an undertaking would dwarf the marches our forces had to make in India. Nor would Bonaparte be able to conduct his operations for long. Any invasion of Russian soil would have to be complete by the time autumn came for fear of being caught in the Russian winter.’ Arthur shook his head. ‘I can’t think for a moment that Napoleon would be so rash as to lead his army against the Tsar. It would be sheer madness to attempt it.’ He paused and sipped his coffee before continuing. ‘Let us assume that he makes peace with Russia. Then Britain alone remains at war with France. The Royal Navy makes French invasion unlikely, and our lack of manpower makes British invasion of the continent an impossibility. So we have a stalemate. For the present. Fortunately Bonaparte has committed a grievous error in banning trade between the continent and Britain. He has caused great resentment amongst his allies and subject territories. In time that will play into our hands. Meanwhile, we must offer the European powers some hope.’

‘It would make a fine change from offering them money,’ Richard interrupted sourly. ‘Pitt nearly bankrupted the country with the vast sums we handed over to our allies. And much good it did us.’

‘I’m afraid that Britain will still have to finance any allies we may find in the future. But there are other means to inspire them. Since you mentioned Pitt, let me tell you of a viable scheme I suggested to him not long before he died. A way to keep the war open on land. One that would vex Bonaparte, and prove that he was not quite so invincible as his propaganda machine makes out.That is to wage war in the Iberian Peninsula.’

‘Spain and Portugal? How would that profit Britain?’

‘While Spain is an ally of France she is a legitimate target for hostility. Spain is also weak militarily and even a modestly sized British army could create havoc. Perhaps enough to force Napoleon to send forces to assist his Spanish allies. And thereby provide the means for us to demonstrate that French soldiers and French generals can be defeated. News of such defeats would be music to the ears of other continental powers.’

‘That may be,’ Richard agreed. ‘But what if Napoleon himself took to the field in Spain? What if he inflicted a crushing defeat on your modestly sized British army? Then such an intervention would only serve to enhance his reputation, diminish ours and discourage any potential allies.’
