The warfare of the next few months was confined to the reduction of the Prussian fortresses which had not yet fallen into the hands of the French. Dantzig surrendered after a long and difficult siege; the little town of Colberg upon the Pomeranian coast prolonged a defence as honourable to its inhabitants as to the military leaders. Two soldiers of singularly different character, each destined to play a conspicuous part in coming years, first distinguished themselves in the defence of Colberg. Gneisenau, a scientific soldier of the highest order, the future guide of Blücher's victorious campaigns, commanded the garrison; Schill, a cavalry officer of adventurous daring, gathered round him a troop of hardy riders, and harassed the French with an audacity as perplexing to his military superiors as to the enemy. The citizens, led by their burgomaster, threw themselves into the work of defence with a vigour in striking contrast to the general apathy of the Prussian people; and up to the end of the war Colberg remained uncaptured. Obscure as Colberg was, its defence might have given a new turn to the war if the Government of Great Britain had listened to the entreaties of the Emperor Alexander, and despatched a force to the Baltic to threaten the communications of Napoleon. The task was not a difficult one for a Power which could find troops, as England now did, to send to Constantinople, to Alexandria, and to Buenos Ayres; but military judgment was more than ever wanting to the British Cabinet. Fox had died at the beginning of the war; his successors in Grenville's Ministry, though they possessed a sound theory of foreign policy, [138] were not fortunate in its application, nor were they prompt enough in giving financial help to their allies. Suddenly, however, King George quarrelled with his Ministers upon the ancient question of Catholic Disabilities, and drove them from office (March 24). The country sided with the King. A Ministry came into power, composed of the old supporters of Pitt, men, with the exception of Canning and Castlereagh, of narrow views and poor capacity, headed by the Duke of Portland, who, in 1793, had given his name to the section of the Whig party which joined Pitt. The foreign policy of the new Cabinet, which concealed its total lack of all other statesmanship, returned to the lines laid down by Pitt in 1805. Negotiations were opened with Russia for the despatch of an English army to the Baltic; arms and money were promised to the Prussian King. For a moment it seemed as if the Powers of Europe had never been united in so cordial a league. The Czar embraced the King of Prussia in the midst of his soldiers, and declared with tears that the two should stand or fall together. The Treaty of Bartenstein, signed in April 1807 pledged the Courts of St. Petersburg, Stockholm, and Berlin to a joint prosecution of the war, and the common conclusion of peace. Great Britain
