THREE:From the air, to an observer who had no idea that his craft had been used, all should seem natural, Larry decided as he and Dick, with Sandy��s discarded garments, and with the caretaker ruefully grumbling, chose a place of concealment.The ships being got afloat again, on the 12th of April Parker sailed away with the main body of the fleet, leaving the St. George (with Nelson) and a few other ships to repair their damages. Sir Hyde Parker went in quest of the Swedish fleet, which consisted only of six ships, and which had taken refuge behind the forts of Karlskrona. Parker sent in a flag of truce, informing them of the armistice with Denmark, and demanding an answer as to the intentions of Sweden. Gustavus, the King of Sweden, hastened to Karlskrona, and on the 22nd informed the English admiral that he was ready to treat with an envoy accredited to the Northern Powers. Admiral Parker then proceeded towards the Gulf of Finland to attack the Russian fleet, but was soon overtaken by a dispatch boat from the Russian ambassador at Copenhagen, announcing that the Emperor Paul had been murdered by his courtiers, and that his son, Alexander, had accepted the proposals of Britain to treat. Parker considered the news of Paul's death as tantamount to the conclusion of peace, and proposed sailing down the Baltic again; but Nelson, who had joined him at Karlskrona, thought very differently. He had blamed Parker's slowness and easiness all through the affair of Copenhagen, and he now wanted to push on to Revel, and destroy the Russian fleet before the ice allowed it to retire into Cronstadt. Sir Hyde Parker refused; and the fleet was on its way down the Baltic when an order came recalling Parker and giving the command to Nelson. He immediately put about and proceeded to Revel, but the thaw had allowed the Russian fleet to get into Cronstadt. Nelson, however, opened communications with the Emperor Alexander, and proposed to land and terminate a convention with him at once. Alexander, not liking to have Nelson's fleet too near, declined the proposal in terms of courtesy, and Nelson took his leave in no complimentary mood. The emperor thought it best to send after him Admiral Tchitchagoff, to assure him that Alexander regretted that any misunderstanding had ever taken place between Russia and Britain; that all the British subjects seized by Paul should be immediately liberated, all their property restored, and that the Czar would be glad to see Nelson at St. Petersburg in any style which he liked to assume. But Nelson had now resolved to return at once to Britain, his shattered health ill bearing the severity of the northern climate; nor was his presence necessary, for on the 17th of June, two days before Nelson went on board the brig which took him to Britain, Lord St. Helens, who had proceeded to St. Petersburg as ambassador, had signed a convention, by which all subjects of dispute between the two countries were ended. Denmark and Sweden came into the convention as a matter of course.
