The loss of the regiment was limited to two serjeants and seven rank and file wounded; the Duke of York expressed his approbation of its conduct in orders. The FOURTEENTH Regiment was employed at the siege of _Valenciennes_, under the Duke of York, and on the 25th of July, it furnished a detachment to take part in storming the horn-work. Lieut.-Colonel Doyle being appointed to the command of one of the attacking columns, obtained permission to place at the head of his party, one hundred volunteers of the FOURTEENTH Regiment, and having assembled the corps, he said, "Soldiers, one hundred volunteers from among you are to lead the column that I am to command _upon a service of the greatest danger_; I have thought it right to state this before I call upon you; such of you as volunteer this dangerous enterprise, recover arms:" when every man brought his musket to the "_recover_." The colonel was much affected by this display of devotion, and said, "Soldiers, I thank you from my heart; where all are equally desirous of facing the greatest danger, I cannot look, or wish, for volunteers. Officers, call out the first ten men for duty in each company." On the 26th of July the following general order was issued.-- "His Royal Highness the Commander-in-chief returns his thanks to Major-General Abercrombie, Colonel Leigh, and Lieutenant-Colonel Doyle, for the gallantry they showed on the attack last night." Haying been constantly exposed to the cannon of the town for seven weeks, the men had acquired great steadiness under fire, the attack was made with signal intrepidity and resolution, and the out-works were carried in gallant style. The regiment had one serjeant and three rank and file killed; one officer, one serjeant, and fourteen rank and file wounded; the flank companies also lost seven men. Three days afterwards the garrison capitulated, and this important fortress was delivered up to the Duke of York. After the surrender of Valenciennes the British troops marched towards Cambray, and they subsequently separated from the Austrians, taking with them a few Imperial regiments, for the purpose of undertaking the siege of Dunkirk. On arriving at Menin, it was ascertained that the French had driven the Dutch from _Lincelles_; that post was recaptured by the British Foot Guards under Major-General Lake, on the 18th of August. The FOURTEENTH Regiment was one of the corps ordered to support the Foot Guards, and was left in possession of the village, after its capture, until that post was restored to the Dutch.
