In this awkward dilemma the king resolved to cut his way through the French, superior as they were, and regain communication with their magazines and their auxiliaries at Hanau. But Noailles was closely watching their movements; and, being aware of what was intended, took instant measures to prevent the retreat. He immediately advanced from their front to their rear, threw two bridges over the Main at Selingenstadt, and despatched his nephew, the Duke de Gramont, to secure the defile of Dettingen, through which the English must pass in their retreat. He also raised strong batteries on the opposite bank of the Main, so as to play on the English as they marched along the river. These preparations being unknown to the English, and still supposing Noailles' principal force lay between them and Aschaffenberg, instead of between them and Dettingen, on the 27th of June, at daybreak, the king struck his tents, and the march on Dettingen began. George showed a stout heart in the midst of these startling circumstances, and the soldiers, having the presence of their king, were full of spirits. George took up his position in the rear of his army, expecting the grand attack to come from that quarter; but presently he beheld his advanced posts repulsed from Dettingen, and the French troops pouring over the bridge of the Main. He then perceived that Noailles had anticipated their movements, and, galloping to the head of his column, he reversed the order of his march, placing the infantry in front and the cavalry in the rear. His right extended to the bosky hills of the Spessart, and his left to the river. He saw at once the difficulty of their situation. Gramont occupied a strong position in the village of Dettingen, which was covered by a swamp and a ravine. There was no escape but by cutting right through De Gramont's force--no easy matter; and whilst they were preparing for the charge, the batteries of the French on the opposite bank of the Main, of which they were previously unaware, began to play murderously on their flank. With this unpleasant discovery came at the same instant the intelligence that Noailles had secured Aschaffenberg in their rear with twelve thousand men, and was sending fresh reinforcements to De Gramont in front. Thus they were completely hemmed in by the enemy, who were confidently calculating on the complete surrender of the British army and the capture of the king.
