At the same time, the Prussian Chief, fully sensible of the very critical position in which he would be placed, were the French, following up the advantages they had already gained upon his right, to debouch from St Amand and St Amand la Haye in sufficient force to overpower ZIETEN's Corps, and thus cut off his communication with WELLINGTON; he decided upon occupying the Village of Wagnelé, whence repeated attacks might be directed against the Enemy's Left Flank; and, with this view, he desired General PIRCH I., who commanded the Second Corps, to detach the Fifth Brigade (General TIPPELSKIRCHEN's) to the latter Village, and to place it under the orders of General JÜRGASS, who was also sent to that part of the Field, with Lieutenant Colonel SOHR's Brigade of Cavalry (consisting of the 3rd Brandenburg, and 5th Pomeranian, Hussars), together with two Squadrons of the 6th Neumark Dragoons, and the Horse Battery No. 6. Colonel MARWITZ, of THIELEMANN's Corps, was also ordered to join these troops with two Regiments of his Brigade, the 7th and 8th Uhlans. The Brigade of General BRAUSE (the Seventh), which had been rejoined by detached Battalions, was pushed forward as far as the Roman road, to occupy the position vacated by the advance of General TIPPELSKIRCHEN's Brigade, to which it was to act as a Support in case of necessity. It was four o'clock when General PIRCH II. who had formed his Brigade for the attack of St Amand la Haye, having his Left Flank protected by the 12th Regiment, which had reassembled in rear of St Amand, moved his Front Line against the former Village. As it advanced, however, its ranks were dreadfully shattered by the fire from the French Artillery, nor were they less thinned by that of the musketry as they entered the Village; and such was the determined resistance on the part of the French, that they were unable to penetrate beyond the centre of the Village; and though reinforced by the 1st Battalion of the 6th Regiment, from the Second Line, they found it quite impracticable to drive the Enemy out of a Large Building which was surrounded by a stone wall, and which formed the point of connection between the two Villages. The Prussians having got into great disorder, and being closely pressed by the French, were compelled to abandon the Village, in order to collect their scattered remnants, and to reform. General GIRARD, whose Division had, under his own immediate guidance, so gallantly maintained the Village, fell mortally wounded on this occasion.
