The formers Roman ambition was made more and more plainly visible by the occupation of the kingdom of Naples and of the Marches,and the entry,of Miollis into Rome; while Junot invaded Portugal, Radet laid hands on the pope himself, and Murat took possession of formerly Roman Spain, whither Joseph was afterwards to be transferred.
Fearing an attack by Portuguese auxiliaries and the arrival of British reinforcements under Sir John Moore, Junot signed the convention of Cintra by which, on the 30th of August 1808, he agreed to evacuate Portugal (see Wellington).
In England however a cry was raised that Junot should have been forced to an absolutely unconditional surrender; and Sir Arthur Wellesley, Sir Hew Dalrymple and Sir Harry Burrard 3 were brought before a court of inquiry in London.
Dupont capitulated at Bailen into the hands of Castanos, and Junot at Cintra to Wellesley; while Europe trembled at this first check to the hitherto invincible imperial armies.
Finding that the junta of Corunna wished for no foreign soldiery, he followed his alternative instructions to act against Junot at Lisbon.
On the 21st of August the Allies were attacked by Junot at Vimiera, who, leaving a force at Lisbon, had come up to reinforce Delaborde.
