At the opening of the campaign Clare’s Dragoons were sent to Ulster in charge of Sir James Cotter. There they formed part of the numerous and well-appointed force commanded by Lord Mountcashel and destined to reduce Enniskillen. On the 26th of July, 1689, they were encountered, near Lisnaskea, by two troops of horse and two companies of foot, directed by Captain Martin Armstrong. An ambush was prepared for them, and Armstrong, attacking them with his horse, made a feint to retire as if in disorder. They, pursuing their opponents, fell into the ambuscade, and, while the enemies’ foot poured a volley into their midst, they were set upon by the horse, and almost cut to pieces. The next year the regiment was called out under the name of Clare’s Dragoons, and it was engaged at the Boyne. There it acted badly, its conduct being the more disgraceful because of the superior style in which the other regiments of James’ cavalry fought at that battle. In the December of 1690, they were quartered at home, and, as on account of their misconduct there at a former time they had been severely punished, Sir Theobald Butler, James’ Solicitor General, wrote to Sir Donogh O’Brien, the high sheriff, a letter, apologising for again sending them into the county of Clare, and suggesting that they should be quartered as the high sheriff should appoint, with injunctions that they were to suffer condign punishment for any outrage they may perpetrate against those upon whom they might be billeted. [4] Whatever the faults of Clare’s Dragoons may have been while in the condition of raw recruits, their shortcomings were afterwards, in many a field, “from Dunkirk to Belgrade,” gloriously expiated.
