Such was the condition into which an army and navy, once illustrious through the victories of Marlborough and Blake, were reduced by the aristocratic imbecility of the Newcastles, Bedfords, and Cumberlands. This last princely general had, in fact, put the climax to his career. He had placed himself at the head of fifty thousand confederate troops, in which there were no English, except the officers of his own staff, to defend his father's Electorate of Hanover. But this ruthless general, who never won a battle except the solitary one of Culloden, against a handful of famished men, was found totally incompetent to cope with the French general, d'Estrées. He allowed the French to cross the deep and rapid Weser, and continued to fall back before them as they entered the Electorate, until he was driven to the village of Hastenbeck, near Hameln, where the enemy overtook and defeated him. He then continued his retreat across the desolate Lüneburg Heath, to cover Stade, near the mouth of the Elbe, where the archives and other valuable effects of Hanover had been deposited for safety. At this time Richelieu succeeded to the command of d'Estrées in this quarter, and he continued to drive Cumberland before him, taking Hameln, Göttingen, and Hanover itself, and soon after Bremen and Verden. Thus were Hanover and Verden, which had cost England such millions to defend, seized by France; nor did the disgrace end here. Cumberland was cooped up in Stade, and compelled, on the 8th of December, to sign a convention at Closter-Seven, by which he engaged to send home the Hesse and Brunswick troops, and to disperse the Hanoverians into different quarters, not to serve again during the war. Meanwhile, Frederick of Prussia was waging a tremendous war with France, Russia, and Austria. To disable Austria before her allies could come up to her aid, he suddenly, in April, made an eruption into Bohemia. His army threaded the defiles of the mountains of the Bohemian frontier in different divisions, and united before Prague, where Marshal Braun and Prince Charles of Lorraine met him with eighty thousand men, his own forces amounting to about seventy thousand. A most obstinate and sanguinary conflict took place, which continued from nine in the morning till eight at night, in which twenty-four thousand Austrians were killed, wounded, or taken prisoners, and eighteen thousand Prussians. The Prussians were destitute of pontoons to cross the Moldau, or their writers contend that not an Austrian would have escaped. But Marshal Daun advancing out of Moravia with another strong army, to which sixteen thousand of the fugitives from Prague had united themselves, Frederick was compelled to abandon the siege of Prague, and march to near Kolin, where he was thoroughly defeated by Daun, with a loss of thirteen thousand of his bravest troops.
