In addition to the furious cannonade to which they were subjected, the foremost of PICTON's British Battalions, more especially the 42nd and 44th Regiments, were exposed to a rapid and destructive fire, which, as soon as the Enemy's Cavalry had been withdrawn, was opened upon them by the French troops advancing from the inclosures of Gemioncourt. To check this, Skirmishers were thrown forward, but from the want of sufficient ammunition, they could reply but very feebly to the fire of their opponents, who, not suffering the same disadvantage, were picking them off as fast as they could load. Their line soon became fearfully thinned, and finally their ammunition was totally exhausted, to which circumstance the Officer on whom the command of them had devolved (Lieutenant RIDDOCK, 44th Regiment) called the attention of Sir DENIS PACK, who ordered him to close his men to their centre and to join his own Regiment. He had just executed the first part of the Order, when the French Cavalry having rallied and reformed, renewed their attacks upon the British Squares. Squadrons of _Cuirassiers_ and Lancers, in their onward course, swept past Lieutenant RIDDOCK and his party, while others intercepted his direct line of retreat. He instantly formed four deep, and with his front rank at the charge, he made good his way through the Enemy's Cavalry, as far as the south face of the Square formed by the 44th Regiment; which, however, was so hotly pressed at the moment as to be unable to receive him, whereupon he ordered his men to lie down close to their bayonets, until a favourable opportunity should offer for their admission within the Square. A repetition of the former scene on this part of the Field now took place, and the attacks, which were conducted with similar impetuosity, were met by a resistance equally undaunted. As if to overawe the Square formed by the Royals and 28th British Regiments, the French Cavalry now made a simultaneous attack upon three of its faces, and these consisted mainly of the latter Corps. PICTON, who was again in the Square, upon perceiving the approach of this apparently overwhelming force, suddenly and emphatically exclaimed, "28th! remember Egypt!" They answered him with a loud cheer, and reserving their fire until the Cavalry had approached within a few yards of the Square, their muskets were coolly and deliberately levelled at their assailants, who in the next moment were hurled back in wild disorder, horses and riders tumbling over one another, and creating indescribable confusion. Similar in their results were all the attacks made upon the other British Squares, which maintained their ground with the same unshaken steadiness and gallantry.
