On their approach, the enemy beat a parley. They desired to march out with arms and baggage. Schomberg refused, and the siege began. The trenches were opened, the batteries were raised, and the cannon thundered against the walls of the old town. Several breaches were made. The attacks were pursued with great vigour for four days, when a general assault was made. The besieged hoisted the white flag. After a parley, it was arranged that the Irish should surrender the place, and march out with their arms, and as much baggage as they could carry on their backs.
Carrickfergus was not taken without considerable loss to the besiegers. Lieutenant Briset, of the Flemish Guards, was killed by the first shot fired from the castle. The Marquis de Venours was also killed while leading the Huguenot regiments to the breach. Rapin distinguished himself so much during the siege that he was promoted to the rank of lieutenant. He was at the same time transferred to another regiment, and served under Lieutenant-General Douglas during the rest of the campaign.
More troops having arrived from England, Schomberg marched with his augmented army to Lisburn, Drummore, and Loughbrickland. Here the Enniskillen Horse joined them, and offered to be the advanced guard of the army. The Enniskilleners were a body of irregular horsemen, of singularly wild and uncouth appearance. They rode together in a confused body, each man being attended by a mounted servant, bearing his baggage. The horsemen were each mounted and accoutred after their own fashion, without any regular dress, or arms, or mode of attack. They only assumed a hasty and confused line when about to rush into action. They fell on pell-mell. Yet they were the bravest of the brave, and were never deterred from attacking by inequality of numbers. They were attended by their favourite preachers, who urged them on to deeds of valour, and encouraged them "to purge the land of idolatry."
Thus reinforced, Schomberg pushed on to Newry. The Irish were in force there, under command of the Duke of Berwick. But although it was a very strong place, the Irish abandoned the town, first setting fire to it. This news having been brought to Schomberg, he sent a trumpet to the Duke of Berwick, acquainting him that if they went on to burn towns in that barbarous manner, he would give no quarter. This notice seems to have had a good effect, for on quitting Dundalk the retreating army did no harm to the town. Schomberg encamped about a mile north of Dundalk, in a low, moist ground, where he entrenched his army. Count Rosen was then at Drogheda with about twenty thousand men, far outnumbering the forces under Schomberg.
About the end of September, King James's army approached the lines of Dundalk. They drew up in order of battle. The English officers were for attacking the enemy, but Schomberg advised them to refrain. A large party of horse appeared within cannon shot, but they made no further attempt. In a day or two after James drew off his army to Ardee, Count Rosen indignantly exclaiming, "If your Majesty had ten kingdoms, you would lose them all." In the meantime, Schomberg remained entrenched in his camp. The Enniskilleners nevertheless made various excursions, and routed a body of James's troops marching towards Sligo.
Great distress fell upon Schomberg's army. The marshy land on which they were encamped, the wet and drizzly weather, the scarcity and badness of the food, caused a raging sickness to break out. Great numbers were swept away by disease. Among the officers who died were Sir Edward Deering, of Kent; Colonel Wharton, son of Lord Wharton; Sir Thomas Gower and Colonel Hungerford, two young gentlemen of distinguished merit. Two thousand soldiers died in the camp. Many afterwards perished from cold and hunger. Schomberg at length left the camp at Dundalk, and the remains of his army went into winter quarters.
Rapin shared all the suffering of the campaign. When the army retreated northward, Rapin was sent with a party of soldiers to occupy a fortified place between Stranorlar and Donegal. It commanded the Pass of Barnes Gap. This is perhaps the most magnificent defile in Ireland. It is about four miles long. Huge mountains rise on either side. The fortalice occupied by Rapin is now in ruins. It stands on a height overlooking the northern end of the pass. It is now called Barrack Hill. The Rapparees who lived at the lower end of the Gap were accustomed to come down upon the farming population of the lowland country on the banks of the rivers Finn and Mourne, and carry off all the cattle that they could seize; Rapin was accordingly sent with a body of troops to defend the lowland farmers from the Rapparees. Besides, it was found necessary to defend the pass against the forces of King James, who then occupied Sligo and the neighbouring towns, under the command of General Sarsfield.
Schomberg was very much blamed by the English Parliament for having effected nothing decisive in Ireland. But what could he do? He had to oppose an army more than three times stronger in numbers than his own. King William, Rapin says, wrote twice to him, "pressing him to put somewhat to the venture." But his army was wasted by disease, and had he volunteered an encounter and been defeated, his whole army, and consequently all Ireland, would have been lost, for he could not have made a regular retreat. "His sure way," says Rapin, "was to preserve his army, and that would save Ulster and keep matters entire for another year. And therefore, though this conduct of his was blamed by some, yet better judges thought that the managing of this campaign as he did was one of the greatest parts of his life."
Winter passed. Nothing decisive had been accomplished on either side. Part of Ulster was in the hands of William; the remainder of Ireland was in the hands of James. Schomberg's army was wasted by famine and disease. James made no use of his opportunity to convert his athletic peasants into good soldiers. On the contrary, Schomberg recruited his old regiments, drilled them constantly, and was ready to take the field at the approach of spring.
His first achievement was the capture of Charlemont, midway between Armagh and Dungannon. It was one of the strongest forts in the north of Ireland. It overlooked the Blackwater, and commanded an important pass. It was surrounded by a morass, and approachable only by two narrow causeways. When Teague O'Regan, who commanded the fort, was summoned to surrender, he replied, "Schomberg is an old rogue, and shall not have this castle!" But Caillemotte, with his Huguenot regiments, sat down before the fortress, and starved the garrison into submission. Captain Francis Rapin, cousin of our hero, was killed during the siege.
