On receiving, on June 9, the news of this untoward event, Junot determined to prevent Caraffa’s troops on the Tagus from following the example of their countrymen. Before they had fully realized the situation, or had time to concert measures for a general evasion, he succeeded in disarming them. Caraffa himself was summoned to the quarters of the commander-in-chief, and placed under arrest before he knew that he was suspected. Of his regiments some were ordered to attend a review, others to change garrisons; while unsuspectingly on their way, they found themselves surrounded by French troops and were told to lay down their arms. All were successfully trapped except the second cavalry regiment, the ‘Queen’s Own,’ whose colonel rode off to Oporto with his two squadrons instead of obeying the orders sent him, and fractions of the infantry regiments of Murcia and Valencia who escaped to Badajoz after an ineffectual pursuit by the French dragoons. But 6,000 out of Caraffa’s 7,000 men were caught, disarmed, and placed on pontoons moored under the guns of the Lisbon forts, whose commanders had orders to sink them if they gave any trouble. Here they were destined to remain prisoners for the next ten weeks, till the English arrived to release them after the battle of Vimiero. The imminent danger that Caraffa’s force might openly revolt, and serve as the nucleus for a general rising of the Portuguese, was thus disposed of. But Junot’s position was still unpleasant: he had only some 26,500 men with whom to hold down the kingdom: if once the inhabitants took arms, such a force could not supply garrisons for every corner of a country 300 miles long and a hundred broad. Moreover, there was considerable probability that the situation might be complicated by the appearance of an English expeditionary army: Napoleon had warned his lieutenant to keep a careful watch on the side of the sea, even before the Spanish insurrection broke out. All through the spring a British force drawn from Sicily was already hovering about the southern coast of the Peninsula, though hitherto it had only been heard of in the direction of Gibraltar and Cadiz. Another cause of disquietude was the presence in the Tagus of the Russian fleet of Admiral Siniavin: the strange attitude adopted by that officer much perplexed Junot. He acknowledged that his master the Czar was at war with Great Britain, and stated that he was prepared to fight if the British fleet tried to force the entrance of the Tagus. But on the other hand he alleged that Russia had not declared war on Portugal or acknowledged its annexation by the Emperor, and he therefore refused to land his marines and seamen to help in the garrisoning of Lisbon, or to allow them to be used in any way on shore. Meanwhile his crews consumed an inordinate amount of the provisions which were none too plentiful in the Portuguese capital.
