At the time the French troops were debouching from Ligny, Colonel STÜLPNAGEL's (the Twelfth) Brigade was posted in front of Sombref; and Colonel ROHR had just pushed forward towards Ligny with the 2nd Battalion of the 6th Kurmark Landwehr, when he perceived three French Cavalry Regiments advancing against the Right Wing of the Brigade; whereupon he gradually retired, and the whole Brigade threw itself into Sombref, just as the French Cavalry made an attack at the entrance of the Village, and captured the two guns of the Battery No. 12, which had been posted there. Major DORVILLE faced about the rear division of the 6th Kurmark Landwehr Cavalry, and gallantly attacked the French Cavalry, in the hope of checking their progress; but the lances of his brave followers were shivered against the cuirasses of their opponents, and for a moment the former could only defend themselves with their broken poles. The Prussian Infantry, however, hastened forward in support; the French were driven out of the Village; and one of the lost guns was retaken. Every exertion was now made to secure the possession of Sombref. General BORCKE (Ninth Brigade) sent thither two Battalions of the 1st Kurmark Landwehr; which, during this movement, fired upon the flank of the Enemy's Cavalry as the latter fell back. The defence of the entrance into the Village from the side of Ligny was confided to the 2nd Battalion of the 6th Kurmark Landwehr, under Colonel ROHR. About this time, General JÜRGASS received Orders to cover with his Cavalry (of the Second Corps) the retreat of the Prussian Infantry from St Amand la Haye and Wagnelé. General BRAUSE, perceiving that the Enemy had attacked Colonel MARWITZ' Cavalry Brigade, on his right, and endangered his communication with the rear, hastened with the Fusilier Battalions of the 22nd Regiment (which had continued in reserve in rear of St Amand la Haye) towards the high road, upon which the greater part of the Seventh Brigade had by this time been collected. The Prussians, on retiring from St Amand la Haye, were closely followed by the French. The 1st Battalion of the 14th Regiment was still in the Hamlet of St Amand when it received the Order to retire. During its retreat it was attacked whilst in a hollow way. It immediately showed a front on each flank, and succeeded in driving back the Enemy. General JÜRGASS now sent forward the 4th Squadron of the Brandenburg Hussars to attack the Enemy's _Tirailleurs_, who were beginning to advance from out of St Amand la Haye. The latter were immediately forced back upon the Village. Somewhat later, however, the French _Tirailleurs_ poured forth in greater numbers from out of Wagnelé, and threw themselves upon the Right Flank of the retreating troops. A _mêlée_ ensued, in which General JÜRGASS was shot in the shoulder. * * * * *
