Three years after its return to France, a war broke out between England and Holland; and in the succeeding year Louis XIV. took part with the Dutch against England, when DOUGLAS' regiment was again ordered to quit the French service, and to return to England: it accordingly landed at Rye, in Sussex, on the 12th of June, 1666, and mustered eight hundred men.[50] The Roman Catholics in several counties in Ireland were, at this period, in a state of insurrection; and in a short time after the arrival of the regiment from France, it was ordered to proceed to Ireland, where it appears to have remained upwards of twelve months. [Sidenote: 1668] [Sidenote: 1670] After the conclusion of the peace of Breda in 1668, the insurrections in Ireland having been suppressed, the regiment was again sent to France; and in an order issued by Louis XIV. in 1670, respecting the rank of regiments, it appears one of the first.[51] [Sidenote: 1672] A war commenced in 1672 between the French monarch and the States General of Holland; King Charles II. of England also declared war against the Dutch; and a British force, commanded by the Duke of Monmouth, was sent to France to co-operate with the army of Louis XIV. in an attack upon Holland. DOUGLAS' Regiment had, in the meantime, been augmented to sixteen companies, and when the army took the field, it formed two battalions; and was in the division of the army commanded by Marshal Turenne. Several fortified towns were captured by the main army; and in June, DOUGLAS' Regiment, being encamped in the vicinity of Nimeguen, was detached with several other corps under the Comte de Chamilly to besiege _Grave_. The attack on the town commenced towards the end of June, and in the early part of July the governor surrendered. A number of the subjects of the British crown, who had entered the service of Holland, being found in garrison, they were permitted to engage in the service of Louis XIV., and were received as recruits in DOUGLAS' Regiment.[52] In August the regiment was withdrawn from the vicinity of Grave, and ordered to join the forces under Marshal Turenne. [Sidenote: 1673] In 1673 eight thousand British troops served with the French army, and were engaged in the siege of _Maestricht_, in which service they evinced signal gallantly; and in repulsing a sally of part of the garrison, the Duke of Monmouth, Captain Churchill (afterwards the great Duke of Marlborough), and twelve private men of the English Life Guards (a squadron of which corps was serving with the French army), highly distinguished themselves.[53] The town surrendered on the 2nd of July.
