T
HE PORTUGUESE CRISIS OF 1807

ceed, providing a full explanation of government policy while consider-
ing all circumstances that might arise. If Portugal shut her ports, but
there were no other hostile measures, Strangford was to remain in Lis-
bon. If anything did arise that made his residence in Lisbon inexpedient
he was to leave for England. If the Regent adhered to his promises to
evacuate Lisbon and asked for Strangford to accompany him, he was to
accompany the Portuguese and act as minister to that court in Brazil.

Canning forwarded a copy of the convention particularly directing
Strangford’s attention to the 2
nd
Article, which ‘stipulates for military aid
from this country to protect the embarkation at Lisbon’. Without guaran-
tees of safety from the Portuguese ‘it is impossible that either a military or
even a naval force of His Majesty’s should be safely trusted in the Tagus’.
Canning had received assurances from Sousa that Portugal would not
consent to ‘any measure unfriendly to the interests of this country’, but
was unsure whether João would resist the demand to shut the ports, par-
ticularly as Sousa had signed the statement of intent declaring the Regent
would close the ports if it was thought France could be appeased. If Por-
tugal did shut the ports, Canning realised all Europe would be closed to
British commerce and he would be ‘compelled to treat them all as one
common enemy’. He thought the Portuguese experience of apparent
danger followed by salvation, as had recently happened in 1806, instilled a
large degree of complacency in the court. If João did evacuate, Canning
mused, it might be possible to establish a Regency Council which, with
British assistance, could organise the defence of the country.

On 22 October Canning informed Strangford an expedition would
sail for Madeira as soon as the Portuguese closed the ports. Next day he
detailed an ‘abundance of rumours…of the most alarming nature’, in-
cluding reports of French troops marching through Spain, that an em-
bargo had been laid on British shipping and the Portuguese navy was
ceded to France. Despite these rumours Canning had ‘on the faith of the
Prince Regent’s letter, of your Lordship’s dispatches, and of M de
Souza’s readiness to give every security that treaty could give, proceed in
the course in which we set out and I have accordingly signed the Con-
vention’. He was worried Sousa had not received official instructions on
two points: the admission of British goods into Brazil, which had been
promised in the convention, and the nature of instructions sent to Ma-
deira. With regard to the evacuation Strangford was to work together
with Almeida. It was ‘the one point to press: and almost equally whether
the Prince is forced to it by the advance of the French army, or is en-
