The destruction of the southern batteries left Copenhagen exposed to bombardment, and the Danes, unable to resist, yet afraid to offend the tsar by submission, prolonged the time from day to day till news arrived which removed all occasion for hostility. Unknown to either of the combatants, the Tsar Paul, the life and soul of the northern confederacy, had been murdered on the night of March 23, ten days before the battle, and with his death the league was practically dissolved. When Nelson advanced further into the Baltic, he found no hostile fleet awaiting him, and the new tsar, Alexander, adopting an opposite policy, entered into a compromise on the subject of maritime rights. The battle of the Baltic is considered by some to have been Nelson's masterpiece. It won for him the title of viscount and for his second in command, Rear-Admiral Graves, the gift of the ribbon of the Bath, but the admiralty, for official reasons, declined to confer any public reward or honour on the officers concerned in it. At the same time, the French occupation of Egypt was drawing towards its inevitable close. Kléber, who was left in command by Bonaparte, perished by the hand of an assassin, and Menou, who succeeded to the command, was not only a weak general, but was prevented from receiving any reinforcements by the naval supremacy of Great Britain in the Mediterranean. On March 21, 1801, the French army was defeated at the battle of Alexandria by the British force sent out under Sir Ralph Abercromby, who was himself mortally wounded on the field. His successor, General Hutchinson, completed his work by taking Cairo, before the arrival of General Baird, who had led a mixed body of British soldiers and sepoys from the Red Sea across the desert to the Nile. The capitulation of Alexandria soon followed. In September the French evacuated Egypt, the remains of their army were conveyed to France in English ships, and Bonaparte's long-cherished dreams of eastern conquest faded away for ever--not from his own imagination, but from the calculations of practical statesmanship.
