‘So why did you put your name to it?’

‘I was ordered to, sir. By General Dalrymple. My signature is a mere form.’

‘I see. And did you agree with the terms of the armistice, as ratified at Cintra?’

Arthur swallowed nervously, but strained to keep his face calm, and his voice unflustered. ‘There is no simple answer, sir. The object of the campaign was to capture Lisbon and eject French forces from Portugal. The treaty achieved that with no loss of life. To that extent I approved of the treaty.’

‘However?’ Dundas prompted.

‘However, I contend that we should have accepted a few more casualties and pursued and destroyed Junot’s army, and thereby damaged wider French morale and inspired our allies. In addition, I think the terms agreed were over-generous to our enemy and have damaged the reputation of Britain. Having defeated Junot, it was absurd to permit his army to be returned to France, rather than be taken into captivity.’

Dundas narrowed his eyes. ‘You are a master of understatement, General Wellesley. However, I feel it only fair to inform you that Sir Hew Dalrymple is unequivocal in ascribing the blame for the treaty to you.’

Arthur felt a cold chill of anger grip his heart.‘I fail to see how I can be held to account for the treaty. If General Dalrymple refused to heed any of my advice in the conduct of the campaign, I am certainly not answerable for the consequences.’

Dundas looked away and conferred quietly with the other panel members, making a few more notes on the papers before him.At length he turned back to Arthur and continued questioning him on more precise details for the next hour, after which Arthur was permitted to leave.

For the next week other officers were called before the inquiry, and then the panel retired to consider the evidence and write their report.As Arthur waited, he made preparations to return to Dublin with Kitty and the children to resume his civilian duties at the castle, but he could not help considering his prospects.At best, he would be cleared of any blame, but he knew that the stigma of the Cintra treaty might stick to his name for many years to come, unless he had the chance to fight again and win a victory that would expunge his part in the armistice.At worst, he faced public censure and would be stripped of his post of Chief Secretary, with no hope of achieving high office at any future date.
