with St. Vincent’s naval force to seize the Portuguese ships. They could
also provide assistance if the Portuguese decided to flee for Brazil. The
disembarkation was to be swift, to prevent the Portuguese from prepar-
ing any possible resistance. Once the troops were landed and deployed in
a position of safety the Portuguese must place their ships ‘in such a state
as to be capable of being immediately removed on the approach of an
enemy’. If the Portuguese argued landing troops would violate their neu-
trality and provide the French and Spanish with a pretext for an attack,
Rosslyn was to state ‘the neutrality of that country is at an end from the
moment that a design of invading its territory & subverting its govern-
ment is openly announced by one of the belligerent parties’. The Talents
were implementing a strategy of pre-emptive intervention because they
could not wait ‘for the actual execution of such a menace before we take
measures for averting or lessening the evil. And experience has but too
plainly shown in too many instances with what facility the French gov-
ernment finds or make pretences for such measures when once an-
nounced’. If the Portuguese did not want help, Simcoe would proceed to
the Mediterranean.

On the same day Windham penned this extensive and exhaustive
explanation of British policy, the Admiralty sent additional instructions
to St. Vincent by the Kingfisher (18). This sloop had been detached from a
force under Rear Admiral Sir Thomas Louis, comprising the Canopus (if
ready) (80), Malta (84), Captain, Ganges, Theseus, Repulse, (74s) and the Re-
sistance frigate (38), with transports containing the troops and victuallers,
which was to join with St. Vincent off the Tagus. St. Vincent was to
communicate to Louis appropriate orders regarding the projected pro-
ceedings at Lisbon. Once the objects had been achieved or as soon as
Louis could be spared, St. Vincent was to direct him to proceed with the
ships under his command, excepting the Resistance, which St. Vincent was
to add to his command, to join with Collingwood off Cadiz.

On 12 August, almost as an afterthought, Windham wondered
whether the government should inform Sousa of the government’s
plans. Howick, upon questioning from the Portuguese minister, admitted
Rosslyn had left England, but Windham, quite wisely, thought it not
‘desirable to tell him all that was intended’.

The same day, taking advan-
tage of contrary winds preventing the convoy from rounding the Downs,
Windham wrote to Rosslyn and Simcoe advising them they would
probably find St. Vincent already in the Tagus. As they would arrive be-
fore the troops, Rosslyn was instructed to communicate his arrival to St.
