After the surrender of Carrickfergus, the regiment advanced with the army to Dundalk, and the Duke Schomberg, believing King James's forces were more than double his own in numbers, formed an entrenched camp. The situation of this camp was particularly unfavourable; the ground was low, and the weather proving wet, the infantry regiments lost many men from disease. The TWELFTH sustained a very serious loss in non-commissioned officers and soldiers; and on the morning of the 28th of October their commanding officer, the gallant Colonel Henry Wharton, died. This officer is represented by historians as possessing a noble disposition, refined understanding, and lofty sentiments of honour, which, added to a tall graceful person, and a gallant bearing, occasioned him to be admired and beloved by the officers and soldiers of his regiment. Story states,--'Colonel Wharton was a brisk, bold man, and had a regiment that would have followed him anywhere, for the officers and soldiers loved him, and this made him ready to push on upon all occasions.... He was of a comely handsome person, gifted with a rare understanding.' Colonel Sir Thomas Gower died on the preceding day, and the remains of these two officers were interred, on the 30th of October, in a vault in Dundalk church, their regiments attending and firing three volleys. King William promoted the lieutenant-colonel of the regiment, RICHARD BREWER, to the colonelcy, by commission dated the 1st of November, 1689. On the 7th of November the regiment struck its tents and marched towards Armagh; and it was employed on various services during the winter. [Sidenote: 1690]
