The enemy’s troops engaged in the last attack retired in the greatest confusion, which caused an unsteadiness and panic throughout the remainder of the French army. By this, the Prussians were relieved from the determined pressure previously made on them by the French right _en potence_; and it soon became evident that they were gaining ground. Zieten’s (first) corps had just joined the left of our line by Ohain; Adam’s brigade was most vigorously pursuing the fugitives, and Vivian’s hussars were rapidly advancing on the enemy’s reserve: all these things combined, convinced the Duke that the favourable moment for making a general attack, was arrived. Closing his telescope with an air of triumph, he ordered the advance of the whole line. This order was received by the eager remains of the army with loud and tremendous cheers. “Then, Wellington, thy piercing eye The crisis caught of destiny. The British host had stood That morn, ’gainst charge of host and lance, As their own ocean rocks hold stanch; But when thy voice had said, Advance! They were their ocean’s flood.”
