'The Moors being vexed, knowing it was impossible to make their approaches against Tangier above ground, resolved to effect it by drawing lines and working underneath the earth; which stratagem of war, it is supposed, they learnt from several French and Spanish mercenaries whom they keep in pay: this practice they were before quite ignorant of.'--The public journals also speak indignantly of some English who clandestinely imported 1500 barrels of gunpowder to the enemy, and say, ''Tis too often the custom of our nation to give away their swords, and fight with their teeth, and furnish our foes with means to cut our own throats.' Numerous losses sustained by the garrison, together with the increased force of the assailants, rendered it requisite to send reinforcements to the relief of the former. For this purpose a detachment left Ireland in the spring of 1680, consisting of four companies of the Royal Regiment of Foot; twelve other companies of the same regiment followed in the same year; five companies of the Foot Guards also sailed for the same destination under the Earl of Mulgrave. In addition to the above reinforcements, a new regiment was raised in 1680, of which _Charles Fitz Charles, Earl of Plymouth_, (a natural son of King Charles II.) was appointed Colonel, and embarked on this service. This latter corps was called 'the Second Tangier Regiment,' and is now the 4th, or King's Own Regiment. It has been stated that the Duke of Marlborough was initiated at Tangier in the first rudiments of war. The same theatre for the display of British valour and enterprise was at this time chosen by several other volunteers, among whom were Charles Lord Mordaunt, the afterwards celebrated Earl of Peterborough, and others of rank and celebrity. In the year 1680 the Earl of Inchiquin vacated his appointment on being made Governor of Jamaica. Colonel Sir Palmes Fairborne[12], of the Queen's Regiment, who succeeded to the command of the fortress on the departure of the Earl of Inchiquin, was, in consequence of his gallant and meritorious services, confirmed in the appointment by his Majesty. The demise of this brave officer, however, occurred before the commission for his appointment was signed; he was wounded in an action with the Moors on the 24th of October, 1680, and died three days after, leaving the charge of the garrison to Lieutenant-Colonel Edward Sackville, of the Coldstream Foot Guards[13]. On the 27th of October the garrison attacked the enemy's lines with determined bravery, and the Queen's Regiment is reported to have '_behaved to admiration_[14].' Considerable loss was however sustained by the English; 'not above fifty men were left in one of the battalions of Lord Inchiquin's Regiment (the Queen's): the English and Scotch behaved as brave and gallant men, and the Gentlemen Volunteers have alike proved themselves men of courage.'
