THREE:It was the aim of Prince Charles to get between Fredericks encampment at Chrudim and his French allies, under Marshal Broglio, at Prague. When discovered by Frederick, the Austrian army was on the rapid march along a line about fifteen miles nearly southwest of Chrudim. It thus threatened to cut Fredericks communication with Prague, which was on the Moldau, about sixty miles west of the Prussian encampment. The310 forces now gathering for a decisive battle were nearly equal. The reader would not be interested in the description of the strategic and tactical movements of the next two days. The leaders of both parties, with great military sagacity, were accumulating and concentrating their forces for a conflict, which, under the circumstances, would doubtless prove ruinous to the one or the other. A battle upon that open plain, with equal forces, was of the nature of a duel, in which one or the other of the combatants must fall.Frederick, finding that he could not rely upon the Saxons, sent to Silesia for re-enforcements of his own troops. Brünn could not be taken without siege artillery. He was capturing Moravia for the King of Poland. Frederick dispatched a courier to his Polish majesty at Dresden, requesting him immediately to forward the siege guns. The reply of the king, who was voluptuously lounging in his palaces, was, I can not meet the expense of the carriage. Frederick contemptuously remarked, He has just purchased a green diamond which would have carried them thither and back again. The Prussian king sent for siege artillery of his own, drew his lines close around Brünn, and urged Chevalier De Saxe, general of the Saxon horse, to co-operate with him energetically in battering the city into a surrender.305 The chevalier interposed one obstacle, and another, and another. At last he replied, showing his dispatches, I have orders to retire from this business altogether, and join the French at Prague.
