But that war brought something more to the British Army even than two famous Scottish regiments. For Mackay had noticed that at Killiecrankie his Scotsmen had not had time to fix the clumsy plug-bayonets into the muzzles of their muskets, and had consequently been unable to meet the Highland charge. He therefore ordered bayonets to be made so that they could be screwed on to the outside of the barrel, thus enabling the men to fire with bayonets fixed. So finally was accomplished the blending of pike and musket into a single weapon, a great era in the history of the art of war.[233] But while recruiting officers were beating their drums through the market towns of England, and Mackay was toiling in pursuit of the Highlanders, Protestant Ireland was standing desperately at bay against King James at Londonderry and Enniskillen. There is no need for me to recall the triumph of the unconquerable defenders of Derry; and it would be pleasanter, were it possible, to pass over the somewhat discreditable behaviour of the Army in relation to their relief. Five days, indeed, before the city was invested two English regiments, the Ninth and Seventeenth Foot, had arrived in the bay, but had been persuaded by the treacherous governor, Lundy, to return and to leave Derry to its fate. Colonels Cunningham and Richards, who commanded these corps, were both of them superseded on their arrival in England; but no further help came until on the 15th of June General Kirke sailed into Lough Foyle with the Second, Ninth, and Eleventh Foot. Even then he would not stir for six whole weeks, when he received positive orders from home to relieve the city. [Sidenote: July 31.] Meanwhile all operations of the Irish Protestants that were not wholly defensive were directed from Enniskillen, which was filled with refugees from Munster and Connaught. With extraordinary energy these Protestants organised a body of horse and another of foot, with which they kept up an incessant harassing warfare against the insurgent Irish. On Kirke's arrival they applied to him for reinforcements. These he refused to give; but he sent them arms and he sent them officers, one of whom, Colonel Wolseley, equalled at Newtown Butler Dundee's feat of Killiecrankie, of beating trained soldiers with raw but enthusiastic levies. After this action the force of the Enniskilleners was reorganised into two regiments of dragoons and three of foot, which are represented among us to this day by the Fifth Royal Irish Dragoons, now Lancers, the Sixth Enniskillen Dragoons, and the Twenty-seventh Enniskillen regiment of the infantry of Line.
