The British Left Cavalry Column continued its retreat, which was towards the little Bridge of Thuy, by deep narrow lanes, converted by the tremendous pour of rain into perfect streams. VIVIAN withdrew the 10th and 18th Hussars from the position he last occupied, but on their approaching the Genappe an interruption occurred in consequence of VANDELEUR's Brigade not having effected its passage across the Bridge; and the delay became so great that he was induced to put about the 18th Hussars, with a view to their affording a Support to the 1st German Hussars, should they require it. In a short time after this, VANDELEUR's Brigade resumed its progress: the 10th Hussars followed; and, as the 1st Hussars, with which Regiment VIVIAN himself was at the moment, continued to maintain a vigorous and effective skirmish, he ordered the 18th to resume its retrograde movement; having previously directed that some men of the 10th Hussars should be dismounted on reaching the opposite bank of the Genappe, and be prepared with their carbines to defend the passage, should the retreat of the remainder of the Brigade be severely pressed. After skirmishing some time, VIVIAN despatched a Squadron of the 1st German Hussars to the Bridge, and the moment he began to do so, the French Cavalry again pushed forward with so much boldness and rapidity as to interpose between the Left Squadron and the main body of the Regiment, and to compel that Squadron to pass the Genappe lower down than the Bridge over which the Brigade passed the little stream. Having ascertained that all was ready, VIVIAN galloped down the road to the Bridge with the remainder of the 1st German Hussars. The French followed them, loudly cheering, but as soon as the Hussars cleared the Bridge, and the Enemy's Dragoons reached it, some of the dismounted men that had been formed along the top of the opposite bank, in rear of a hedge, overlooking the Bridge and a hollow way, through which the road led from it up the ascent, opened a fire upon the foremost of the French Lancers that had come up to the other end of the Bridge, while the remainder of the 10th, and the whole of the 18th Hussars, were drawn up along the rising ground or bank. The good countenance here shown by VIVIAN's Brigade, combined with the soft and miry state of the ground after the thunderstorm had set in, completely checked the pursuit by the Enemy's Cavalry, which now turned towards the high road.
