I have been going through my old MSS notes in a bid to find all the relevant information I once collected for my novel in one place. In the process I found the following: a poem, possibly written by Lord Carlisle, either after the peace preliminaries that became the treaty of Amiens were signed in the autumn of 1801 or (more likely) early 1803 before war broke out between Britain and France again.
Carlisle was a member of Lord Grenville’s parliamentary faction. The Grenvilles considered the Peace of Amiens to be a disaster for Britain. Britain pledged to hand back all her wartime conquests except for Trinidad and Ceylon, to restore Egypt to the Ottoman Empire and to give Malta back to the Knights of St John. In return France was to evacuate Italy and her Portuguese territories, but the Grenvilles were unequivocal in their opinion that Britain had made all the sacrifices. The Prime Minister, Henry Addington, they considered to be foolish and inept. The poem has to be read with this in mind.
“Dialogue between Mr Addington and Bonaparte”
With a friendship most hearty
To you great Bonaparte
I open my pitiful case.
If by Peace you don’t aid me,
By the God who has made me,
I shan’t keep a moment my place.
And wherefore thus sad in tone
My good Mr. Addington;
I wish you to govern yr. Nation.
I’ll do all that I can,
To preserve such a Man
As yourself, in that high situation.
Only Give me my share,
(What you’ll very well spare)
All Italy, Holland, & Spain.
With Switzerland too,
Tis a trifle to you,
While you keep the rule of the Main.
Lord for this my dear Chief,
I should hang like a thief:
O grant me an Island, or two!
A free port , that with ease,
You may shut when you please,
And something for Jenky  to chew.
Well, I’ll give you Ceylon,
Tis a hundred to one
That this may prove dust for your rabble;
Trinidad may impose,
So dont turn up your nose,
I know you don’t venture to squabble. 
Did not Hawkesbury state,
(Many thanks to his prate),
How all nations refused you their aid.
Then to War if you’re led
Pitt jumps over your head:
And a fine piece of work you’ll have made.
But I smell all the trick,
Pitt expects us to break:
And that he’ll have to manage the war.
But I know how to fit him; 
Take my Peace, and then quit him;
Let your place, not the terms be your care.
 Over the course of 1802 and early 1803, Napoleon declared himself President of the Cisalpine Republic [Italy] and sent troops into Switzerland. He also remodelled the Dutch government. Much of this was in contravention to Amiens, and also to previous treaty engagements with Austria (Luneville, 1801)
 The Cape of Good Hope. Amiens made this into a free port
 Robert Bankes Jenkinson, Lord Hawkesbury, the Foreign Secretary. Later Lord Liverpool.
