eleven o'clock
Wolfe hoped that , if he attacked one of the redoubts , the French would come down to defend it , and that a battle might be so brought on ; or that , if they did not do so , he might find a spot where the heights could be stormed with some chance of success . At low tide , it was possible to ford the mouth of the Montmorenci , and Wolfe intended that the troops from his camp , on the heights above that river , should cross here , and advance along the strand to cooperate with Monckton 's brigade , who were to cross from Point Levi . On the morning of the 31st of July , the Centurion , of 64 guns ; and two armed transports , each with 14 guns , stood close in to one of the redoubts , and opened fire upon it ; while the English batteries , from the heights of the Montmorenci , opened fire across the chasm upon the French lines . At eleven o'clock , the troops from Point Levi put off in their boats , and moved across the river , as if they intended to make a landing between Beauport and the city . For some hours , Montcalm remained ignorant as to the point on which the English attack was to be made , but became presently convinced that it would be delivered near the Montmorenci , and he massed the whole of his army on that flank of his position . At half-past five o'clock the tide was low , and the English boats dashed forward , and the troops sprang ashore on to the broad tract of mud , left bare by the tide ; while , at the same moment , a column 2000 strong moved down from the height towards the ford at the mouth of the Montmorenci . The first to land were thirteen companies of Grenadiers , and a detachment of Royal Americans , who , without waiting for the two regiments of Monckton 's brigade , dashed forward against the redoubt at the foot of the hill .
