Arthur was sorely tempted to refuse. He had had no hand in drafting the terms of the armistice, and some of the clauses were far too generous to the enemy. But if he refused it would only cause further ill will between him and his superior. He nodded, and took the pen offered to him by General Kellermann.Then the French officer slid the documents across the table and indicated the space beneath his own signature. Arthur dipped the nib in the ink, composed his hand and signed his name with neat, deliberate strokes. When he had finished he laid the pen down and sat back as the documents were whisked away. Kellermann handed one to Dalrymple and folded the other to tuck inside his coat as he stood up.

‘I must return to General Junot and tell him the good news.’

Dalrymple and Arthur rose to their feet and exchanged handshakes with the French officer before Kellermann strode out of the tent, mounted his horse, and galloped away. As Arthur watched him go, he could not help doubting the wisdom of what his commander had agreed to. But at least the French would quit Portugal. Once Portugal was established as a base of operations the British army could turn its attention to Spain, and the next, far more ambitious, phase in the campaign to eject the French from the Peninsula.

A week later General Junot surrendered the Portuguese capital to the British. Dalrymple, reinforced by Sir John Moore and another fifteen thousand troops, moved south to occupy the city. There was a brief celebration in the streets as the inhabitants cheered the departure of the French garrison, but joy soon turned to disbelief and anger when it became apparent that the ‘property’ that the enemy were taking with them, with British consent, included gold and silver plate from Lisbon’s churches and other loot taken from the royal palaces and homes of the wealthy. It was a bad business, and Arthur, who had signed the armistice, began to dread the manner in which it would be received in London. Worse still was the mood in the army. The plodding nature of Dalrymple, and the common knowledge that he had permitted the French to get the better of him, soured the mood of officers and common soldiers alike.The fact that they continued to report to Arthur in the first instance caused understandable resentment in his superiors. Arthur felt himself to be in a peculiar bind. On the one hand he had proved himself to be a fine commander who had the respect and affection of his men, which meant that it was impossible for him to serve with the army in a subordinate role. On the other, he did not wish to quit in case senior officers complained that he was unwilling to serve where he did not command.
