During the morning of the 27th July, the troops had been marching on the different points marked for their occupation, and had taken ground hitherto unmolested by the enemy; but at noon Mackenzie’s division was suddenly and furiously assailed by two heavy columns, which attacked the wood and convent. Partially surprised, the 87th and 88th regiments were thrown into a momentary confusion; and the French penetrated between the two brigades which formed the division. Immediately, by the exertions of their officers, the 31st, 45th, and 60th rifles were brought forward, and these regiments covered their companions, while they retired from the wood into the plain, retreating in beautiful order along the heights on the left of the position which they were directed to occupy. The enemy continued their attack, and it had now extended partially along the whole line, growing more animated as the evening began to fall. The left, where the British stood, at once appeared the grand object of the marshals. They directed a strong force against it, forming their infantry into columns of battalions, which advanced in double quick, supported by a furious cannonade. Mackenzie’s division having retired a little, and, at the moment, forming a second line, the brunt of the assault fell upon a smaller brigade under General Donkin, then in possession of the height. The French, though they came on with imposing bravery, were checked in front; but from the weakness of his brigade, Donkin’s flank was turned on the left, and the hill behind crowned by the enemy. But that success was momentary. Hill instantly led up the 48th, 29th, and 1st battalion of detachments. A close and murderous volley from the British was followed by a charge. The French were forced from the position with great loss; and the ridge was again carried by a wing of the 29th with the bayonet. There was a brief space of quiet; but determined to win the key of the position, though darkness had now set in, the French in great force once more rushed forward to wrest the height from its defenders, and in the gloom the assailants and the assailed nearly touched each other. The red flash of a well-delivered volley disclosed to the British the dark array that threatened them. The order was given to advance, and again the British bayonet drove the columns down the hill. No fighting could have been more desperate than that which marked this night attack. A feint had been made by Lapisse upon the Germans in the centre, while, with the _élite_ of their infantry, Ruffin and Vilatte ascended the heights, which, at every loss, they seemed more resolute in winning. A terrific slaughter ensued. Could it be otherwise? So desperately was this night fighting maintained, and the regiments were so closely engaged, that in the _mêlée_, some of the men fought with clubbed muskets.
